Professional Washing Machine Troubleshooting: Common Faults, Problems & Solutions
Washing machines are essential household appliances that make daily life considerably easier. However, when they malfunction, the inconvenience can be significant. Whether you’re dealing with excessive detergent suds, water flooding your laundry room floor, or a machine that simply refuses to start, understanding common washing machine problems can save you time, money, and frustration.
In Nairobi, Kenya, washing machine repair services are readily available, but having basic troubleshooting knowledge empowers you to identify issues quickly and determine whether you need professional assistance or can handle the repair yourself. This comprehensive guide covers the most frequent washing machine problems, their causes, and practical solutions to get your appliance running smoothly again.
Understanding When to Call a Professional vs. DIY Repairs
Before diving into specific problems, it’s important to understand which repairs you can safely attempt yourself and which require professional expertise. Simple issues like cleaning filters, checking hoses, or adjusting load balance are typically safe for homeowners to handle. However, electrical components, motor repairs, transmission issues, and anything involving complex disassembly should be left to certified technicians.
Safety First: Always disconnect your washing machine from the power source before attempting any troubleshooting or repairs. Water and electricity are a dangerous combination, and taking proper safety precautions can prevent serious injury or death.
“Regular maintenance can prevent up to 80% of common washing machine problems. Monthly cleaning and quarterly inspections significantly extend appliance lifespan and performance.”
Problem #1: Washing Machine Won’t Turn On
One of the most frustrating washing machine issues is when the appliance completely fails to respond when you attempt to start it. This problem can stem from several causes, ranging from simple power supply issues to more complex internal component failures.
Power Supply Issues
The first step in diagnosing a washing machine that won’t turn on is verifying that the appliance is receiving electrical power. Using a multimeter, test the outlet voltage to confirm electricity is flowing to the machine. If the outlet shows no voltage, check your home’s electrical panel for tripped circuit breakers.
Washing machines draw significant power, especially during heating cycles, which can occasionally trip breakers. If you find a tripped breaker, reset it and attempt to start the machine again. However, if the breaker trips repeatedly, this indicates a more serious electrical problem that requires immediate attention from a qualified electrician.
If the breaker isn’t tripped but the outlet still lacks power, the problem lies with the outlet itself. Turn off the corresponding breaker and contact a licensed electrician to replace the faulty outlet and investigate the underlying cause. Never attempt electrical repairs without proper training and tools.
Motor Overheating Protection
Modern washing machines feature thermal protection systems that automatically shut down the motor if it overheats. This safety feature prevents motor damage and potential fire hazards. When the motor overheats, the machine will refuse to start until it cools to a safe temperature, which typically takes 30 minutes to an hour.
If your motor overheats occasionally, it may not indicate a serious problem. However, frequent overheating suggests underlying issues such as overloaded wash cycles, restricted ventilation around the machine, bearing problems, or motor bearing wear. Persistent overheating requires professional diagnosis to identify and resolve the root cause before permanent motor damage occurs.
Faulty Lid Switch
Washing machines incorporate safety mechanisms that prevent operation when the lid is open. The lid switch is a small plastic component located beneath the lid that must be activated for the machine to run. This prevents injuries from hands entering a spinning drum.
Inspect the lid switch for damage, wear, or improper positioning. Sometimes debris or detergent buildup can prevent the switch from making proper contact. Clean the switch area and ensure nothing obstructs its activation. If the switch appears broken or fails to click when the lid closes, replacement is necessary and relatively inexpensive.
Timer Knob Alignment
Some washing machine models, particularly older units, require precise timer knob alignment with control panel graphics. If the knob sits even slightly out of position, the machine interprets this as an incomplete setting and refuses to start.
To test this theory, advance the timer to the next position and attempt to restart the machine. If it starts after adjusting the timer, the issue was simply misalignment. Take care in future to ensure the timer knob fully engages each setting position.
Problem #2: Washing Machine Not Draining Properly
Drainage problems range from minor inconveniences to major flooding disasters. When your washing machine fails to drain, water remains in the drum after the cycle completes, potentially soaking your laundry and creating puddles on your floor. Understanding the drainage system helps you diagnose and resolve these issues efficiently.
Drain Hose Complications
The drain hose is often the culprit in drainage problems. This flexible tube carries water from your washing machine to your home’s drainage system, and various issues can obstruct or impede its function.
Clogs and Blockages: Remove the drain hose and visually inspect its interior for blockages. Lint, small clothing items, and detergent residue commonly accumulate inside the hose, restricting water flow. Use a garden hose to flush stubborn clogs, forcing water through from both ends to dislodge debris.
Kinks and Bends: Check the entire length of the drain hose for kinks or sharp bends that restrict water flow. Even slight kinks can significantly reduce drainage capacity, causing water to back up into the machine. Straighten any kinks and ensure the hose maintains smooth, gradual curves.
Lint Filters: Many drain hoses feature inline lint filters that trap debris before it enters your home’s plumbing. These filters require regular cleaning to maintain proper drainage. Locate and clean these filters monthly to prevent blockages.
Installation Height Issues: The drain hose must be positioned above the water level in the washing machine tub to prevent back-siphoning. If the hose sits too low, water can flow back into the machine even as it attempts to drain. Additionally, ensure the hose isn’t sealed into the standpipe, as this can create vacuum conditions that slow or prevent drainage.
Standpipe Requirements: Your home’s standpipe should be at least 1.25 inches in diameter and no taller than 96 inches. Standpipes outside these specifications can cause drainage problems that no amount of machine maintenance will resolve.
Drain Pump Failures
The drain pump actively moves water from the washing machine tub through the drain hose. When this component fails or becomes jammed, drainage problems inevitably follow.
Foreign Object Jams: Coins, pens, small toys, and especially socks frequently find their way into the drain pump, jamming the impeller and preventing operation. You’ll often hear a humming sound as the motor attempts to turn the jammed pump. To inspect the pump, drain the tub manually, disconnect the hoses, and check for foreign objects in both the pump housing and inlets.
Mechanical Failures: Drain pumps contain bearings that wear over time and can seize. When bearings fail, the pump becomes extremely difficult or impossible to turn. In belt-driven systems, a seized pump can break the drive belt or even damage the motor if the issue isn’t addressed promptly. The motor continues running, creating tension on the belt until it breaks or burns through. In severe cases, this can cause the motor itself to seize.
If the pump impeller blades have broken or the pump mechanism has failed completely, replacement is the only solution. Fortunately, drain pumps are relatively affordable components, and replacement typically resolves drainage issues completely.
Excessive Detergent Use
Using too much detergent creates excessive suds that interfere with proper drainage. Modern high-efficiency detergents are highly concentrated, and using quantities appropriate for older detergent formulations results in far too many bubbles.
Excessive suds prevent water from draining efficiently, as the foam occupies space and creates resistance in drainage pathways. If you notice excessive suds during the wash cycle, reduce the amount of detergent you use. Follow manufacturer recommendations carefully, adjusting for water hardness and load size.
Problem #3: Washing Machine Won’t Spin or Agitate
When your washing machine fills with water but fails to spin or agitate, your clothes remain soaking wet and dirty. This problem stems from various mechanical and electrical issues that prevent the drum from moving as designed.
Overloaded or Unbalanced Loads
Before suspecting mechanical failure, rule out the simplest cause: an improperly loaded washing machine. Overloading forces the drum beyond its designed capacity, preventing proper rotation. Even if clothes fit inside the drum, exceeding weight limits triggers safety mechanisms that prevent spinning.
Similarly, unevenly distributed clothes create balance problems. Modern washing machines feature sensors that detect imbalance conditions and stop the spin cycle to prevent damage. If clothes bunch on one side of the drum, the resulting off-balance condition prevents spinning.
To resolve load issues, remove some items if you’ve overloaded the machine, or redistribute clothes evenly throughout the drum. Clothes should move freely within the drum without being packed tightly. As a general rule, fill the drum no more than three-quarters full to allow adequate movement and proper cleaning.
Lid Switch and Speed Selector Problems
The lid switch serves as a critical safety component, preventing operation when the lid is open. Located inside the cabinet near the door frame, this switch must engage properly for the machine to spin. A faulty or misaligned lid switch prevents the machine from entering spin cycles.
Test the lid switch by pressing it manually with the machine turned on. If the machine starts spinning, the switch mechanism may be worn or misaligned. Replacement switches are inexpensive and relatively easy to install.
Additionally, verify that the speed selector switch is properly positioned on a specific setting rather than between settings. Some machines won’t operate if the selector sits ambiguously between two speeds.
Drive Belt Issues
Washing machines use one or more drive belts to transfer motor power to the drum. Over time, these rubber belts wear, crack, and eventually break. Signs of belt wear include visible cracking, fraying, or glazing on the belt surface. Any belt showing these symptoms should be replaced proactively before it breaks completely.
If you find a broken belt, don’t simply replace it without further investigation. Belts typically break because another component has seized or created excessive resistance. Check that all pulleys rotate freely by hand. A seized pulley will quickly destroy a new belt, leaving you with the same problem shortly after replacement.
Common causes of belt breakage include seized pulleys, damaged bearings, transmission problems, and foreign objects jamming movement. Address the root cause before installing a new belt to prevent recurring failures.
Motor and Transmission Complications
The main drive motor powers both spinning and agitating functions. In most designs, the motor directly drives spinning while using a transmission with crank-type gears and connecting rods to create the back-and-forth agitating motion.
If the splines connecting the agitator to the drive shaft strip or wear, agitation becomes weak or stops entirely while spinning may continue normally. This component wear occurs gradually through normal use and requires replacement.
Some washing machines use reversing motors that change rotation direction. If the drum spins perfectly in one direction but won’t move in the opposite direction, the motor likely needs replacement. Motor replacements represent significant repairs best left to qualified technicians.
The motor connects to the transmission through a coupler that wears over time. This plastic or rubber component absorbs shock and vibration, gradually deteriorating until it fails. Coupler replacement is relatively straightforward and much less expensive than motor or transmission replacement.
Transmission and clutch problems represent some of the most complex washing machine repairs. These components involve numerous moving parts, precise adjustments, and potential for serious injury during repair. If you suspect transmission or clutch failure, contact a professional repair service rather than attempting DIY repairs.
“Nearly 40% of washing machine no-spin issues are caused by simple overloading or imbalanced loads. Always check the basics before assuming mechanical failure.”
Problem #4: Washing Machine Leaking Water
Water leaks create immediate problems, potentially damaging floors, walls, and nearby items. While leaks seem serious, many causes are simple and inexpensive to fix. Systematic troubleshooting helps identify the leak source and appropriate solution.
Drain Hose Leaks
When leaking occurs only during the spin cycle, suspect the drain hose first. The increased water pressure during spinning can reveal weaknesses in hose connections or damage to the hose itself.
Inspect all drain hose connections for tightness, ensuring clamps are secure but not over-tightened. Examine the entire hose length for cracks, holes, or wear. Even small damage can leak significantly during high-pressure drainage. Check the hose connection point at the washing machine carefully, as this area experiences considerable stress and commonly develops leaks.
If the hose end shows damage, you may be able to cut off the damaged section and re-clamp the hose. However, if damage extends beyond the end or the hose shows multiple problem areas, replacement is more practical and reliable.
Fill Hose Problems
The fill hoses that supply water to your washing machine must remain in excellent condition to prevent leaks. These hoses experience constant water pressure and flex during machine vibration, creating conditions that promote wear and eventual failure.
Inspect fill hoses for bulges, cracks, or signs of wear. Ensure connections are secure at both the machine and wall supply points, but avoid over-tightening, which can damage connection threads or crush rubber washers.
Always use new rubber washers when reconnecting fill hoses. These small rubber rings create watertight seals, but they compress and deform over time. Old washers may appear functional but often leak under pressure. Replace them whenever hoses are removed and reconnected.
Water Inlet Valve Leaks
The water inlet valve controls water flow into the washing machine. This component can develop leaks due to mineral deposit buildup, rust, or mechanical failure. Inspect the valve area carefully for signs of water, mineral deposits, or rust.
Hard water accelerates mineral buildup inside the valve, creating rough surfaces that prevent proper sealing. If mineral deposits are visible, the valve likely requires replacement. While some technicians attempt to clean inlet valves, replacement provides more reliable long-term results.
Detergent-Related Leaks
Excessive suds can overflow the washing machine tub, creating what appears to be a leak. This problem is particularly common when using hard water with a water softener. Soft, hot water requires significantly less detergent than cold, hard water to achieve effective cleaning.
If you notice excessive suds or foam escaping from the machine, reduce your detergent quantity. Most people use far more detergent than necessary, wasting money and creating cleaning problems. Modern high-efficiency detergents are highly concentrated, requiring only small amounts per load.
Front-Load Door Seal Issues
Front-loading washing machines feature a large rubber door seal that prevents water from escaping during operation. This seal accumulates debris, detergent residue, and mold over time. As buildup increases, the door can’t seal properly, allowing water to seep out during wash cycles.
Carefully clean the door seal monthly using a mixture of white vinegar and water or a mild bleach solution. Pay particular attention to the seal folds where debris accumulates. After cleaning, leave the door open after each wash to allow the seal to dry completely, preventing mold growth.
Drain Pump Seal Failure
Drain pumps feature a shaft seal at the pulley connection point. This seal prevents water from leaking along the pump shaft. Over time, wear causes this seal to fail. Many pumps include a weep hole that allows small amounts of water to escape as the seal begins failing, providing an early warning before complete failure occurs.
Any water around the drain pump area indicates seal problems. Drain pumps can sometimes be rebuilt with new seals, but replacement is often more cost-effective and reliable, particularly for older machines.
Tub and Tub Seal Leaks
The washing machine tub itself can develop leaks, though this is less common than other leak sources. If the tub cracks from extended off-balance operation or impact damage, water will leak directly from the damaged area.
Tub leaks generally make washing machine repair uneconomical. New tubs cost nearly as much as replacement machines. You might attempt temporary repairs using marine-grade epoxy, but this provides only short-term relief at best.
The main tub seal, located where the outer tub connects to the transmission, represents one of the most challenging repairs. This seal requires extensive disassembly to access and replace. Given the labor involved, many technicians recommend evaluating whether replacement is more practical than repair, particularly for older machines.
Problem #5: Washing Machine Not Dispensing Detergent
Automatic detergent dispensers offer convenience but can malfunction due to buildup or incorrect product use. Understanding how these systems work helps you maintain them properly and resolve dispensing problems.
Dispenser Cleaning Requirements
Detergent dispensers require regular cleaning to function properly. Residue from detergents, fabric softeners, and bleach gradually accumulates in dispensers and feed lines, eventually creating blockages that prevent proper dispensing.
Clean your detergent dispenser monthly by pouring one cup of warm distilled white vinegar into each dispenser compartment. Run a complete wash cycle without clothes. The vinegar dissolves residue and flushes clogs from dispenser channels, restoring proper function.
For stubborn buildup, remove the dispenser drawer completely if possible and soak it in hot vinegar solution. Use a small brush to scrub away deposits, paying particular attention to small holes and channels where residue commonly accumulates.
Using Correct Products
Always use products specifically designed for your washing machine type. Dispensers designed for liquid products will clog when powder products are used, and vice versa. Check your owner’s manual to confirm which product forms your machine supports.
High-efficiency (HE) washing machines require HE-specific detergents. Regular detergents create excessive suds that interfere with HE machine cleaning action and can damage components. Always verify product compatibility before use.
Problem #6: Washing Machine Shaking and Moving
Violent shaking and movement during operation indicates balance or stability problems. While alarming, these issues typically have simple solutions that restore stable operation.
Leveling the Machine
Washing machines must sit perfectly level to operate without excessive vibration. An unlevel floor causes machines to rock and shake, particularly during high-speed spin cycles. The motion can damage the machine, floor, and surrounding structures.
If your floor isn’t level, place the washing machine on a 3/4-inch plywood platform. This creates a stable, level surface for the machine. Use shims under the plywood if necessary to achieve perfect leveling, though quality plywood often provides sufficient improvement without shimming.
Adjusting Washer Feet
All washing machines feature adjustable feet that allow precise leveling on uneven floors. The front feet typically include threaded adjustment mechanisms with lock nuts to secure settings. Adjust each front foot to the appropriate height, then tighten the lock nut firmly to prevent movement.
Rear feet may be adjustable like the front or feature self-leveling designs. For self-leveling rear feet, tip the machine forward onto its front feet, raising the rear feet approximately three inches off the floor. Set the machine back down, allowing the rear feet to automatically adjust to proper height.
After adjustment, verify that the machine doesn’t rock when you push on opposite corners. Any rocking indicates incomplete leveling that will cause vibration problems during operation.
Balancing the Load
Even a properly leveled washing machine will shake if the load inside becomes unbalanced. This commonly occurs when washing large items like blankets or comforters that bunch up on one side of the drum.
If your machine begins shaking during a cycle, stop it and manually redistribute the load. You may need several attempts to achieve proper balance, especially with large or heavy items. Consider washing particularly large items at a laundromat with oversized machines designed for such loads.
Avoid overloading the machine, which creates imbalance and prevents clothes from moving freely. The drum should be no more than three-quarters full, allowing clothes room to circulate during washing and distribute evenly during spinning.
“A washing machine that’s just 1 degree off level can experience up to 3 times more vibration during spin cycles, significantly increasing wear on internal components and reducing appliance lifespan.”
Problem #7: Noisy Washing Machine Operation
Unusual noises during washing machine operation often signal developing problems. While some sounds are normal, others indicate issues requiring attention before they worsen.
Gurgling Sounds
Gurgling noises during draining suggest a partial blockage in the drain system. The sound occurs as water struggles to flow past an obstruction. While the blockage may not completely prevent drainage currently, it will worsen over time and eventually cause complete drain failure and flooding.
Inspect and clean the drain hose, removing any partial blockages. Check the pump filter and drain pump inlet for debris. Addressing partial blockages now prevents future emergencies.
Clicking Noises
Clicking sounds typically indicate foreign objects in the drain system. Coins, buttons, bobby pins, and small toys commonly find their way into washing machines through clothing pockets.
Inspect the drain pump and drain pathways for foreign objects. Remove anything you find to prevent potential pump damage or complete blockage. Develop a habit of checking pockets before washing to prevent future problems.
Buzzing or Humming
A humming or buzzing sound with no drum movement indicates a jammed drain pump. The motor continues running, attempting to turn the pump, but an obstruction prevents movement. This situation can damage the pump motor if allowed to continue.
Immediately stop the machine and inspect the drain pump for obstructions. Remove any foreign objects you find. If the pump shows damage from the jam, replacement may be necessary, but often removing the obstruction restores normal function.
Grinding or Scraping
Grinding or scraping sounds during operation suggest bearing problems or drum alignment issues. These sounds indicate metal-on-metal contact that will cause progressive damage if not addressed. Such problems require professional diagnosis and repair, as they involve complex disassembly and precision component replacement.
Problem #8: Washing Machine Odors
Musty or mildew smells from your washing machine indicate mold and bacteria growth. These organisms thrive in the dark, damp environment inside washing machines, creating unpleasant odors that can transfer to your laundry.
Understanding Bio-Film Formation
All washing machines develop bio-film, a layer of decaying organic matter combined with detergent residue, minerals, and moisture. This film provides ideal conditions for mold and bacteria growth. Some machines are more prone to bio-film buildup than others, particularly front-loading designs with their tight-sealing doors.
Left untreated, bio-film odors intensify and contaminate laundry. In severe cases, the smell can spread to the entire laundry room and adjacent spaces. Regular cleaning prevents bio-film accumulation and associated odor problems.
Preventing and Treating Odors
Detergent Management: Use the correct amount of detergent for your water hardness and machine type. Excessive detergent creates residue that feeds mold and bacteria growth. Follow manufacturer recommendations carefully, and consider reducing quantities if you notice excessive suds.
Temperature Settings: Hot water dissolves bio-film and kills mold and bacteria. Run hot wash cycles periodically, even if you typically wash in cold water. Running a hot wash as your final load of the day helps sanitize the machine and reduce moisture.
Drain Pump Filter Maintenance: Clean the drain pump filter monthly. This often-neglected component traps debris and creates perfect conditions for mold growth when not maintained. Most people only clean this filter when problems develop, but monthly cleaning prevents issues.
Door and Seal Care: For front-loading machines, wipe the door seal dry after each use and leave the door open between wash cycles. This allows moisture to evaporate rather than creating a humid environment ideal for mold growth.
Machine Cleaning Cycles: Run a cleaning cycle monthly using washing machine cleaner, white vinegar, or a bleach solution. This dissolves bio-film and kills odor-causing organisms. Many modern machines include dedicated cleaning cycles that optimize water temperature and agitation for effective sanitization.
Problem #9: Washing Machine Won’t Complete Cycles
A washing machine that runs continuously beyond the normal cycle duration indicates timer malfunction. This problem wastes water, energy, and time while potentially damaging clothes through excessive washing.
Diagnosing Timer Issues
If your machine continues running indefinitely without advancing through the cycle stages or stopping when complete, the timer is likely defective. The timer controls cycle progression, signaling when to advance from washing to rinsing to spinning and finally stopping.
Access the control panel and locate the timer mechanism. Inspect the timer contacts for corrosion, scorching, or visible damage. These signs confirm timer failure and indicate replacement is necessary.
Timer Replacement
Timer replacement involves disconnecting electrical connections and mounting hardware. While not particularly complex, the numerous wire connections require careful attention to ensure correct reconnection. Taking photographs before disconnecting wires helps ensure proper reassembly.
If you’re uncomfortable working with electrical components, contact a professional technician. Timer replacement is a common repair that most washing machine service providers can complete quickly and affordably.

Complete Refrigerator Repair Guide: Common Problems & Solutions
Understanding Your Refrigerator: Why It Matters
Your refrigerator is arguably the most critical appliance in your home. Operating 24 hours a day, 365 days a year, it works tirelessly to preserve your food, reduce waste, and keep your family safe from foodborne illnesses. Unlike other appliances that you use intermittently, your refrigerator never gets a break, which makes it particularly susceptible to wear and tear over time.
Modern refrigerators are sophisticated machines containing electrical components, mechanical systems, and refrigeration technology that all must work in harmony. When something goes wrong, it can be frustrating and costly if not addressed promptly. Understanding common refrigerator problems can help you identify issues early, potentially saving you hundreds of dollars in food spoilage and emergency repair costs.
This comprehensive guide will walk you through the most common refrigerator problems, their symptoms, causes, and solutions. Whether you’re experiencing cooling issues, strange noises, or your fridge won’t start at all, this article will help you diagnose the problem and determine whether it’s a DIY fix or requires professional assistance.
When Your Refrigerator Won’t Start: Critical Components to Check
1. Defective MCB (Miniature Circuit Breaker)
One of the first things to check when your refrigerator fails to start is the miniature circuit breaker, commonly known as the MCB. This safety device is designed to protect your refrigerator and home electrical system from damage caused by electrical overloads or short circuits.
Symptoms of MCB Issues:
- Refrigerator won’t turn on at all
- No lights, sounds, or any sign of power
- Other appliances on the same circuit may also be affected
- The breaker switch in your electrical panel is in the “off” or middle position
Why MCBs Fail: MCBs can trip for several reasons, including power surges, overloaded circuits, or internal electrical faults within the refrigerator itself. Age and repeated tripping can also weaken the MCB over time, making it more sensitive to minor fluctuations.
What to Do: First, locate your home’s electrical panel and check if the breaker for your refrigerator has tripped. If it has, try resetting it by switching it fully to the “off” position, then back to “on.” If the breaker trips immediately or repeatedly, this indicates a more serious electrical problem that requires professional diagnosis. Never attempt to bypass or replace a breaker with a higher-rated one, as this creates a serious fire hazard.
2. Insufficient Electrical Current or Voltage
Refrigerators require a stable power supply to operate correctly. Most household refrigerators in many regions operate on 220-240V or 110-120V depending on your location, and any significant deviation from this can cause performance issues or prevent the unit from starting altogether.
Understanding Voltage Problems: Low voltage is more common than you might think, especially in areas with aging electrical infrastructure, during peak usage times, or in homes with inadequate wiring. When voltage drops below the required level, your refrigerator’s compressor may struggle to start or may not start at all. Conversely, voltage spikes can damage sensitive electronic components.
How to Check Voltage: To properly diagnose voltage issues, you’ll need a multimeter or voltage tester. These devices are essential diagnostic tools for any homeowner and are relatively inexpensive.
Recommended Multimeters:
- HTC Instrument MAS 830L Digital Pocket Multimeter DMM – A compact, reliable option for basic voltage testing
- Uni-T UT-33D Digital Multimeter with Continuity Buzzer – Features an audible continuity tester for easier troubleshooting
- Freshdcart DT-266 Clamp Multimeter – Ideal for measuring current draw without disconnecting wires
- Mextech DT-603 Digital Multimeter – Offers high accuracy for more precise measurements
Testing Procedure:
- Set your multimeter to the AC voltage setting appropriate for your region
- Insert the probes into the refrigerator’s outlet (be careful not to touch the metal parts)
- Read the voltage display
- Compare it to your refrigerator’s rated voltage (found on the specification plate)
If the voltage is consistently more than 10% above or below the rated voltage, contact an electrician to assess your home’s electrical system. This isn’t just a refrigerator problem—it’s a whole-house electrical issue that needs addressing.
Motor and Compressor Issues: The Heart of Your Refrigerator
3. Faulty Fan Motor
Modern refrigerators typically contain two or more fan motors: the evaporator fan motor (inside the freezer compartment) and the condenser fan motor (usually located at the back or bottom of the unit). These motors are crucial for proper air circulation and heat dissipation.
Evaporator Fan Motor Problems: The evaporator fan circulates cold air from the freezer coils throughout both the freezer and refrigerator compartments. When this motor fails, you’ll notice:
- Freezer stays cold, but refrigerator compartment warms up
- Frost buildup on the back wall of the freezer
- Unusual noises like squealing, grinding, or clicking
- The fan doesn’t run when you open the freezer door (most models stop the fan when the door opens, but you should hear it running when the door is closed)
Condenser Fan Motor Problems: The condenser fan cools the compressor and condenser coils. Signs of failure include:
- Refrigerator runs constantly but doesn’t cool properly
- Compressor feels extremely hot to the touch
- Food spoiling despite the unit running
- Unusual vibrating or rattling sounds from the bottom or rear of the fridge
Replacement Options by Brand: Different refrigerator brands often require specific replacement motors. Here are some options:
- Fan Motor for Godrej Frost Free Refrigerators (Genuine OEM parts ensure proper fit)
- Fan Motor for Samsung Refrigerators with 2-Pin Connector
- Fan Motor for LG/BPL Frost Free/Double Door Refrigerators with 3-Pin Connectors
- Fan Motor for Videocon Frost Free Refrigerators with 2-Pin Connector
- Fan Motor for Whirlpool Refrigerators
DIY vs. Professional Replacement: While replacing a fan motor is technically possible for someone with electrical knowledge, it requires accessing internal components, working with electrical connections, and potentially removing panels or shelving. If you’re uncomfortable working with electrical appliances, it’s safer to call a professional. The labor cost is typically reasonable, and you’ll have peace of mind knowing it’s done correctly.
4. Faulty Compressor: When the Heart Stops Beating
The compressor is often called the “heart” of your refrigerator because it drives the entire refrigeration cycle. This motor-driven pump compresses refrigerant gas, increasing its pressure and temperature before sending it through the condenser coils where it releases heat and condenses into a liquid.
Signs of Compressor Failure:
- Refrigerator won’t cool at all, despite running
- Clicking sound followed by silence (compressor trying to start but failing)
- Compressor feels cold to the touch when it should be warm
- Burning smell coming from the back of the refrigerator
- Continuous running without achieving proper cooling
- The unit shuts down shortly after starting
Why Compressors Fail: Compressors are built to last, often running for 10-20 years without problems. However, they can fail prematurely due to:
- Electrical surges or power fluctuations
- Lack of proper lubrication
- Dirty condenser coils causing overheating
- Manufacturing defects
- Normal wear and tear over many years
- Refrigerant leaks causing the compressor to work harder
Compressor Maintenance: While you can’t service the internal components of a compressor, you can extend its life through proper maintenance:
- Keep condenser coils clean (more on this below)
- Ensure adequate ventilation around the refrigerator
- Avoid overloading the refrigerator, which makes the compressor work harder
- Address cooling problems promptly before they strain the compressor
- Consider using a surge protector to protect against electrical damage
Repair or Replace? Compressor replacement is one of the most expensive refrigerator repairs, often costing 50% or more of a new refrigerator’s price. If your refrigerator is older than 10 years and the compressor fails, it’s usually more economical to replace the entire unit. However, if your refrigerator is relatively new and still under warranty, compressor replacement may be covered.
Cooling System Problems: When Cold Air Isn’t Flowing
5. Dirty Condenser Coils: A Hidden Culprit
Located at the back or bottom of your refrigerator, condenser coils are responsible for releasing heat extracted from inside the refrigerator into the surrounding air. These coils contain high-pressure, high-temperature refrigerant that must dissipate heat to complete the refrigeration cycle.
The Problem with Dirt: Over time, dust, pet hair, cooking grease particles, and other airborne debris accumulate on these coils. This layer of grime acts as insulation, preventing efficient heat transfer. When the coils can’t release heat properly:
- The compressor must run longer to achieve the same cooling
- Energy consumption increases significantly (raising your electricity bill)
- The compressor may overheat and shut down prematurely
- Overall cooling efficiency decreases
- The refrigerator may eventually stop working entirely
How to Clean Condenser Coils: This is one of the most important DIY maintenance tasks you can perform:
- Safety First: Unplug the refrigerator or turn off the circuit breaker
- Access the Coils: Depending on your model, the coils may be behind a removable panel at the back or beneath a kick plate at the bottom front
- Vacuum First: Use a vacuum cleaner with a brush attachment to remove loose debris
- Deep Clean: Use a refrigerator coil cleaning brush (available at hardware stores) to reach between the coil fins
- Vacuum Again: Remove any loosened debris
- Clean the Area: Vacuum the floor and surrounding area to prevent immediate re-soiling
- Reassemble and Restore Power: Replace any panels and plug the refrigerator back in

Regular coil cleaning can extend your refrigerator’s life by years and reduce energy costs by 25% or more.
6. Refrigerant (Coolant) Shortage: The Invisible Problem
Refrigerant, also called coolant, is the lifeblood of your refrigerator’s cooling system. This chemical compound circulates through a closed-loop system, absorbing heat from inside the refrigerator (through the evaporator coils) and releasing it outside (through the condenser coils).
Understanding the Refrigeration Cycle: In the evaporator coils (inside the freezer), low-pressure liquid refrigerant absorbs heat and evaporates into a gas. The compressor then pressurizes this gas, which flows to the condenser coils where it releases heat and condenses back into a liquid. This liquid then flows back to the evaporator through an expansion valve, and the cycle repeats continuously.
Signs of Low Refrigerant:
- Gradual loss of cooling over days or weeks
- Freezer compartment cools adequately, but fresh food section doesn’t
- Frost buildup on evaporator coils that doesn’t melt during defrost cycles
- Hissing or bubbling sounds (indicating a refrigerant leak)
- Ice buildup around the evaporator coils in unusual patterns
- Compressor runs constantly but doesn’t achieve proper temperature
Why Refrigerant Levels Drop: Unlike your car, refrigerators use a completely sealed system. Refrigerant doesn’t “run out” under normal circumstances—if it’s low, there’s a leak somewhere in the system. Common leak points include:
- Corroded or damaged coils
- Faulty connections at joints and fittings
- Punctured tubing from physical damage
- Manufacturing defects in the sealed system
Professional Repair Required: Refrigerant handling requires specialized equipment, certification, and knowledge. The process involves:
- Locating and repairing the leak
- Evacuating the remaining refrigerant properly (environmental regulations)
- Pressure testing the system to ensure the leak is fixed
- Recharging with the correct type and amount of refrigerant
- Testing for proper operation
Never attempt to add refrigerant yourself. Improper handling can damage the compressor, void warranties, violate environmental laws, and pose health risks.
Electrical Component Failures: The Brain of Your Refrigerator
7. Faulty Start Capacitor: The Spark That Starts the Engine
The start capacitor is a small but crucial component that provides the extra electrical boost needed to start the compressor motor. Think of it like the starter in your car—without it, the engine (compressor) won’t turn over.
How Start Capacitors Work: When your thermostat signals that cooling is needed, it sends power to the start capacitor. The capacitor stores electrical energy and then releases it in a powerful burst to overcome the compressor’s initial resistance and get it spinning. Once the compressor is running, a run capacitor (if equipped) helps maintain smooth operation.
Symptoms of Capacitor Failure:
- Clicking sound with no compressor start-up
- Compressor hums but doesn’t start
- Lights work but compressor won’t run
- Refrigerator starts, runs briefly, then shuts off
- Compressor feels hot but isn’t running
- Circuit breaker trips when the compressor tries to start
Why Capacitors Fail: Capacitors are consumable components with a limited lifespan, typically 5-10 years. They fail due to:
- Normal aging and degradation
- Excessive heat exposure
- Voltage fluctuations
- Power surges
- Manufacturing defects
- Overworking due to dirty coils or low refrigerant
Testing and Replacement: Testing a capacitor requires a multimeter with capacitance measurement capability and knowledge of electrical safety. Because capacitors store electrical charge even when unplugged, they can deliver a dangerous shock if not properly discharged. For this reason, capacitor replacement is best left to professionals unless you have proper training and equipment.
Replacement capacitors are relatively inexpensive (typically $20-$50), making this a cost-effective repair when performed by a technician.
8. Faulty Thermostat: The Temperature Controller
The thermostat is your refrigerator’s brain, constantly monitoring temperature and controlling when the compressor and fans operate. This temperature-sensing device ensures your food stays at safe temperatures while preventing excessive cooling that would waste energy and potentially freeze items.
How Thermostats Function: Most refrigerator thermostats use a sensing bulb filled with gas that expands and contracts with temperature changes. This mechanical movement triggers electrical contacts that turn the compressor on and off. Modern electronic thermostats use sensors and circuit boards to achieve the same goal with greater precision.
Signs of Thermostat Problems:
- Temperature fluctuations despite consistent settings
- Refrigerator runs constantly without cycling off
- Refrigerator doesn’t run at all, even with proper power
- Temperature control knob turns but doesn’t affect cooling
- Food freezing in the fresh food compartment
- Frost and ice buildup in unusual locations
- Display panel shows errors or incorrect temperatures (electronic models)
Testing Your Thermostat: You can perform a basic thermostat test:
- Turn the thermostat to the coldest setting—you should hear a click and the compressor should start within a few minutes
- Turn it to the warmest setting—the compressor should shut off
- If there’s no response to these adjustments, the thermostat may be faulty
Replacement Thermostats by Brand: Thermostats are brand and model-specific. Here are some common options:
- Thermostat Compatible with Videocon Single Door Refrigerators
- Thermostat for Godrej Single Door Refrigerators (available for both old and new models)
- Thermostat for Whirlpool Single Door Refrigerators
- Thermostat for Samsung Single Door Refrigerators
- Universal Thermostats for LG, Samsung, Godrej, Videocon, Intex, Whirlpool and other brands
- Thermostat for LG Single Door/Direct Cool Refrigerators
- Thermostat for Videocon Direct Cool/Manual Defrost models
Professional Installation Recommended: While thermostat replacement isn’t extremely complex, it requires disconnecting electrical wires, removing the control panel, and properly calibrating the new unit. Incorrect installation can lead to temperature control problems or electrical shorts. Professional installation typically costs $100-$200 including parts and labor.
Additional Common Problems and Solutions
9. Door Seal Issues
A damaged or worn door gasket allows warm air to enter continuously, forcing the compressor to run more often. Check for tears, hardening, or gaps in the seal. Clean the gasket with warm soapy water, and test the seal by closing the door on a piece of paper—if you can pull it out easily, the seal needs replacement.
10. Defrost System Failures
Automatic defrost systems prevent ice buildup, but when components like the defrost timer, heater, or thermostat fail, you’ll see excessive frost in the freezer. This frost acts as insulation, reducing cooling efficiency.
11. Drain Blockages
The defrost drain can become clogged with food particles or ice, causing water to back up and leak inside or underneath the refrigerator. Flushing the drain with hot water mixed with baking soda usually clears minor blockages.
When to Call a Professional
While some maintenance tasks are DIY-friendly, certain repairs require professional expertise:
- Any work involving refrigerant
- Compressor replacement
- Electrical repairs beyond simple component replacement
- Sealed system repairs
- Complex diagnostic procedures
- Problems covered under warranty (DIY attempts may void coverage)
Professional refrigerator repair typically costs $150-$400 depending on the problem, which is often more economical than premature replacement.

- Look for signs of fraying, burning, or damaged insulation
- Check the plug prongs for burns or corrosion
- Replace the power cord if you discover any damage
Terminal Block Testing
The terminal block is where the power cord connects to the dryer’s internal electrical system. Testing this component requires the power to be ON, so exercise extreme caution:
- Remove the power cord access panel (typically on the back of the dryer)
- With the dryer plugged in, use your multimeter to check voltage at the terminal block
- You should read approximately 240 volts for an electric dryer
- If the terminal block is faulty, replace it following these steps:
- Unplug the dryer
- Disconnect the power wires from the terminal block
- Unscrew the mounting screws
- Use a flathead screwdriver to remove the terminal block from its housing
- Install the new terminal block by reversing these steps
Door Switch Problems
The door switch serves as a safety mechanism, preventing the dryer from operating when the door is open:
Cleaning the Door Switch:
- Inspect the door gasket and switch area for lint and debris accumulation
- Clean thoroughly using a soft brush or cloth
- Use rubbing alcohol on a cotton swab to clean metal contact areas
- Ensure the door latches firmly when closed
Testing and Replacing the Door Switch:
If cleaning doesn’t resolve the issue:
- Locate the door switch (usually near the door opening)
- You may need to open the cabinet to access it, depending on your model
- Disconnect the wires from the switch
- Set your multimeter to the RX1 (resistance times one) setting
- With the door open, touch the probes to the switch terminals—you should read infinity
- Press the door switch button—the reading should change to zero
- If readings are incorrect, replace the door switch
Thermostat Malfunction
Dryers contain multiple thermostats that regulate internal temperature for different drying cycles:
Locating the Cycling Thermostat:
- The cycling thermostat is typically located in the airflow path as air exits the drum
- Common locations include inside the venting/exhaust system or on the blower wheel housing
- It’s an oval-shaped component approximately 1.5 inches long
Testing the Thermostat:
- Label and disconnect the two wires connected to the thermostat
- Allow the thermostat to reach room temperature
- Set your multimeter to RX1
- Touch the probes to each terminal
- A working thermostat will show a reading of zero (indicating continuity)
- Any other reading indicates the thermostat needs replacement
Start Switch Failure
The start switch initiates the dryer’s operation when you press the start button:
Testing Procedure:
- Remove the control knob from the start switch
- Open the control panel to access the switch
- Disconnect the leads from the switch
- Set your multimeter to RX1
- Clip the probes to the switch terminals—you should read infinity
- Press the start button while maintaining probe contact
- The reading should change to zero
- Replace the start switch if these readings are incorrect
Thermal Fuse Issues
Many modern dryers incorporate a thermal fuse as a safety feature to prevent overheating:
Understanding the Thermal Fuse:
- Located in the exhaust duct within the rear panel
- Once tripped, it cannot be reset and must be replaced
- When blown, the dryer won’t start (or may run without heating)
- Typically trips due to restricted airflow from lint buildup
Testing and Replacement:
- Locate the thermal fuse (consult your owner’s manual)
- Disconnect the wire leads
- Test for continuity with your multimeter set to RX1
- A functional fuse shows zero resistance; infinity means it’s blown
- Install a new thermal fuse if needed
- Important: Investigate and address the cause of overheating (usually lint buildup) to prevent future fuse failure
Problem #2: Dryer Making Unusual Noises
Dryers contain numerous moving parts that can produce various sounds as they wear. Different noises indicate specific problems, and identifying the sound can help pinpoint the failing component.

Drive Belt Issues
The main drive belt wraps around the drum and connects to the motor pulley:
Identifying Belt Problems:
- A worn belt creates a thumping sound as it slaps against the drum
- Inspect for cracks, fraying, or glazing
- Check belt tension—it should have minimal slack but not be overly tight
Belt Replacement:
- Access the belt by removing the front or top panel
- Release tension on the idler pulley
- Remove the old belt
- Loop the new belt around the drum with the ribbed side against the drum
- Thread the belt through the idler pulley and around the motor pulley
- Ensure proper alignment before reassembling
Gas Dryer Clicking Sounds
If you have a gas dryer and hear periodic clicking, this is typically normal:
- The sound comes from the gas valve opening and closing
- This is part of the normal ignition cycle
- Only investigate if the clicking is continuous or accompanied by other problems
Problem #3: Dryer Won’t Heat
A dryer that tumbles but produces no heat is a common issue with several potential causes. Always check the simple solutions first before investigating more complex problems.
Check Settings First
Before disassembling anything:
- Verify you’ve selected a heated drying cycle (not air dry or fluff)
- Ensure the temperature setting is appropriate for your load
- Check that the timer is functioning and advancing
- For gas dryers, confirm the gas supply valve is fully open
Thermal Fuse Testing (Critical Safety Component)
The thermal fuse prevents dryer fires by shutting down the heating system if temperatures become dangerously high:
Location and Testing:
- Find the thermal fuse in the exhaust duct area (back panel)
- It’s usually housed in white plastic and has two wire terminals
- Disconnect the wires and test for continuity with a multimeter
- A blown fuse shows infinite resistance
- Replace with an exact match for your model
Preventing Future Fuse Failure:
- Clean the lint filter after every load
- Inspect and clean the exhaust vent system annually
- Ensure adequate airflow around and through the dryer
- Never vent the dryer into an enclosed space
Heating Element Inspection (Electric Dryers)
The heating element consists of nichrome wire coils that generate heat:

- Handle the new element carefully—oils from your hands can damage it
- Take photos before disconnecting wires to ensure correct reconnection
Gas Burner System (Gas Dryers)
Gas dryers require proper burner operation for heat production:
Ignitor Inspection:
- Open the lower access panel while the dryer runs
- Observe the ignitor during a heat cycle
- A working ignitor glows bright orange or yellow
- If it doesn’t glow, check for cracks or discoloration
- Test for continuity if no visible damage is apparent
- Replace the ignitor if it’s cracked or shows no continuity
Gas Valve Coils:
If the ignitor glows but the burner doesn’t light:
- The problem is likely the gas valve coils
- These electromagnetic coils open the gas valve when energized
- They’re located on the burner assembly (black cylinders with wires)
- Test each coil for continuity
- Replace the gas valve assembly if coils are defective
Flame Quality:
- A properly burning flame should be blue
- Yellow or orange flames indicate incomplete combustion
- Adjust the air shutter or call for service if flame color is wrong
Thermostat Testing
Multiple thermostats control dryer temperature:
High-Limit Thermostat:
- Located near the heating element or on the blower housing
- Prevents overheating by cutting power to the element
- Test for continuity at room temperature (should show zero resistance)
- Replace if it shows infinite resistance
Cycling Thermostat:
- Controls temperature during normal operation
- Opens and closes to maintain set temperature
- Test at room temperature for zero resistance
- Should cycle between continuity and no continuity when heated
Temperature Switch/Selector
This control allows you to choose drying temperature:
Testing Procedure:

Power Cord Issues (Electric Dryers)
Electric dryers require substantial power (240 volts):
Important Safety Notes:
- Never use an extension cord with a dryer
- Ensure the dryer is plugged directly into a dedicated outlet
- The circuit should be rated for the dryer’s amperage requirements
Inspection:
- Unplug the dryer
- Examine the plug for burns, melting, or corrosion
- Check the cord for cuts, fraying, or damage
- Inspect the terminal block connections for burns or loose connections
- A partially damaged cord may allow the drum to turn but prevent heating
Problem #4: Dryer Takes Too Long to Dry Clothes
Extended drying times waste energy, increase wear on clothing, and signal underlying problems. Most causes are related to restricted airflow.
Lint Filter Maintenance
The lint filter is your first line of defense against reduced airflow:
Proper Maintenance:
- Clean the lint filter before or after every load
- Remove the screen and rinse with warm water monthly to remove fabric softener residue
- Use a soft brush to remove stubborn buildup
- Replace the filter if it’s damaged or warped
- Never operate the dryer without the lint filter in place
Exhaust Vent System
A clogged vent system is the most common cause of slow drying:
External Vent Inspection:
- Go outside to your dryer’s exhaust vent
- Start the dryer and hold your hand near the vent opening
- You should feel strong, warm airflow
- Weak or no airflow indicates a blockage
- Remove any visible lint, bird nests, or debris
- Ensure the exterior flapper opens fully during operation
Internal Ductwork Cleaning:
- Disconnect the dryer from the wall vent
- Use a dryer vent cleaning brush or vacuum attachment
- Clean from both ends—exterior and interior
- Consider professional cleaning if the vent is long or has multiple bends
- Clean the vent at least once per year, more often with heavy use
Vent System Best Practices:
- Keep vent runs as short and straight as possible
- Use rigid metal ducting instead of flexible plastic or foil
- Limit the number of 90-degree turns
- Ensure the vent terminates outside, never in an attic or crawlspace
- Replace crushed or damaged ductwork
Dryer Location and Ventilation
Environmental factors affect drying efficiency:
Room Temperature:
- Dryers operate most efficiently in rooms above 45°F (7°C)
- Cold ambient air reduces heating efficiency
- Consider insulating laundry rooms in cold climates
Air Circulation Requirements:
- Allow minimum 1 inch clearance in front of the dryer
- Provide at least 5 inches clearance behind the dryer
- For closet installations, ensure ventilation openings at top and bottom of door
- Adequate airflow prevents overheating and improves performance
Loading and Operation Practices
How you load and operate the dryer affects drying time:
Load Size:
- Avoid overloading—clothes need room to tumble freely
- Don’t combine heavy items (towels, jeans) with lightweight fabrics
- Dry similar fabric types together for even drying
- Small loads may not engage moisture sensors properly
Moisture Sensor Issues:
- Two metal strips inside the drum front detect moisture
- Fabric softener residue coats these sensors
- Clean sensors monthly with rubbing alcohol and cotton ball
- For small loads, use timed dry instead of automatic sensing
Fabric Softener Usage:
- Use only one dryer sheet per load
- Excess sheets block the lint filter and reduce airflow
- Consider liquid fabric softener in the washer instead
- Some newer dryers work better without dryer sheets
Proper Washing Preparation
Issues may originate before clothes enter the dryer:
- Ensure washing machine spin cycle removes excess water
- Oversudsing in the washer leaves clothes overly wet
- Use the correct amount of detergent
- Check that washer drain and spin cycles function properly
Problem #5: Drum Won’t Tumble
When the drum fails to rotate, the dryer becomes completely non-functional. This problem usually involves mechanical components rather than electrical issues.
Drive Belt Failure
The drive belt is the most common culprit when the drum won’t turn:
Symptoms:
- Motor runs but drum doesn’t rotate
- You can turn the drum easily by hand (no resistance)
- Burning rubber smell before failure

- Ensure the belt hasn’t slipped off its pulleys
Installing a New Belt:
- Loop the new belt around the drum (ribbed side toward drum)
- Thread the belt under the idler pulley
- Wrap the belt around the motor pulley
- Pull the idler pulley to create proper tension
- Manually rotate the drum several times to seat the belt
- Ensure the belt tracks centrally on all pulleys
Pro Tip: When replacing the belt, also replace the idler pulley. A worn idler pulley stresses the new belt and shortens its lifespan, potentially causing premature failure.
Idler Pulley Problems
The idler pulley maintains tension on the drive belt:
Diagnosis:
- Squealing or squeaking during operation before failure
- Visible wear, wobbling, or rough rotation
- Bearing feels rough when spun by hand
- Pulley no longer applies proper tension
Replacement Importance:
- A failed idler pulley allows the belt to slip
- Replace along with the belt for optimal performance
- Relatively inexpensive compared to repeat service calls
- Takes minimal additional time since you’re already accessing the area
Drum Support Roller Failure
Drum support rollers bear the weight of the drum and wet laundry:
Symptoms of Worn Rollers:
- Drum turns with difficulty or not at all
- Extremely loud during operation before failure
- Visible flat spots or grooves on roller surface
- Rough feel when spinning by hand
Replacement Process:
- Remove the drum from the cabinet
- Take photos of roller orientation before removal
- Remove all drum support rollers (front and/or rear)
- Clean the mounting shafts thoroughly
- Install new rollers—replace all of them simultaneously
- Lubricate roller axles if recommended by manufacturer
- Reassemble and test for smooth operation
Motor or Component Seizure
If the motor runs but strains, or doesn’t run at all, components may have seized:
Diagnostic Process:
- Remove the drive belt completely
- Check the blower fan housing for obstructions (lint, socks, debris)
- Attempt to turn the motor shaft by hand
- If extremely difficult or impossible, the motor has seized
Motor Issues:
- Seized motors typically cannot be repaired economically
- Check the motor’s start capacitor first—it’s less expensive
- Motor replacement is complex but doable for experienced DIYers
- Professional installation may be worth the cost
Testing Other Components:
- With the belt removed, turn the motor on briefly
- If the motor runs smoothly, check other components
- Try rotating the drum by hand
- Resistance indicates problems with drum rollers, idler pulley, or glides
- Since you have the dryer open, consider replacing all wear items
Problem #6: Clothes Come Out Wrinkled
Wrinkled laundry frustrates everyone and often has simple solutions that don’t require any tools.
Common Causes and Solutions
Clothes Left in Dryer Too Long:
- Remove clothes promptly when cycle ends
- Use the dryer’s signal or end-of-cycle buzzer
- Set a timer if your dryer lacks an audible signal
- Immediately fold or hang items
- Briefly run the dryer with a damp towel if items have cooled and wrinkled
Improper Cycle Selection:
- Use the permanent press cycle for wrinkle-prone fabrics
- This cycle includes a cool-down period that reduces wrinkling
- Allow wrinkle-guard features to complete their cycles
- Match cycle intensity to fabric type
Incorrect Load Size:
- Overloading prevents proper tumbling
- Clothes remain bunched and wrinkle
- Underloading can cause similar issues
- Fill the drum 1/2 to 3/4 full for best results
- Don’t dry multiple loads consecutively without removing completed loads
Mixing Fabric Types:
- Don’t combine heavy and lightweight items
- Separate by fabric weight and care requirements
- Delicate items wrinkle more easily when mixed with heavy items
- Sort laundry before washing to simplify drying
Washing Machine Issues:
- Excessive water temperature causes some fabrics to wrinkle
- Use appropriate water temperature for fabric type
- Ensure proper water levels during wash cycle
- Remove clothes from washer promptly to prevent wrinkling before drying
Fabric Softener Considerations:
- Use fabric softener to reduce static and soften fibers
- Add liquid softener to washing machine, or
- Use one dryer sheet per dryer load
- Don’t overuse—more isn’t better
Prevention Strategies
- Shake out clothes before placing in dryer
- Untwist twisted items
- Button shirts and zip zippers
- Turn clothes right-side-out if desired
- Remove clothes immediately when dry
- Fold or hang promptly
- Consider a steamer for stubborn wrinkles
Problem #7: Dryer Runs but Clothes Stay Damp
When the dryer completes its cycle but clothes remain damp, several factors may be responsible.
Moisture Sensor Problems
Modern dryers use moisture sensors to detect dryness:
Sensor Function:
- Two metal sensor strips inside the drum detect moisture through electrical conductivity
- Dry clothes = low conductivity = end cycle
- Fabric softener residue interferes with sensor accuracy
Cleaning Procedure:
- Locate sensor strips (usually inside front rim of drum)
- Dampen a cotton ball with rubbing alcohol
- Wipe sensors thoroughly until residue is removed
- Clean sensors monthly for optimal performance
- Avoid excessive fabric softener to reduce buildup
Load Size Considerations:
- Small loads may not contact sensors adequately
- Use timed dry cycle for very small loads
- Moisture sensors work best with medium to large loads
- Ensure dryer is level for proper sensor contact
Dryer Not Level
An unlevel dryer affects sensor accuracy and drum rotation:
Leveling Procedure:
- Place a level on top of the dryer (front to back and side to side)
- Adjust the leveling legs by turning them in or out
- Check that all four legs contact the floor firmly
- Recheck with level
- Test with a load to ensure proper operation
Cycle Selection Issues
Using the Wrong Cycle:
- Automatic sensors may be less effective for certain fabrics
- Heavy items like comforters need more time
- Delicate items may need lower heat but longer cycles
- Use timed dry for problematic loads
Heat Setting Too Low:
- Ensure adequate heat selection for fabric type
- Low heat extends drying time significantly
- Balance fabric care with effective drying
Airflow and Venting Review
Refer to the “Takes Too Long to Dry” section for complete airflow troubleshooting. Restricted airflow is a common cause of incomplete drying.

Thermostat Failure
Faulty thermostats can’t regulate temperature properly:
Testing High-Limit Thermostat:
- Allow thermostat to cool to room temperature
- Test for continuity using multimeter
- Should show continuity at room temperature
- Should open (no continuity) when heated above its limit
- Replace if it doesn’t function correctly
Cycling Thermostat Issues:
- Stuck in closed position allows continuous heating
- Test with multimeter for proper cycling behavior
- Replace if contacts remain closed continuously
Heating Element Short (Electric Dryers)
A grounded or shorted heating element causes uncontrolled heating:
Testing Procedure:
- Test element for continuity (should show some resistance)
- Test element to ground (should show infinite resistance)
- Any continuity to ground indicates a short
- Replace element if testing reveals a short to ground
Ventilation Obstruction
Restricted airflow causes heat buildup:
Comprehensive Check:
- Clean lint filter—even partial blockage causes overheating
- Inspect entire exhaust vent system

DISHWASHER REPAIR
How to diagnose common dishwasher problems
- Common Dishwasher Problems
From leaks, to cold water and noisy machines, we’ve broken down what might be going wrong with your dishwasher. If your dishwasher is acting up then there might be a solution that can save you from the horrors of hand washing.
- Leaks
Dishwasher leaks are usually easy enough to identify. Check the following things:
Too much detergent – make sure you’re not overloading on detergent. A soapy residue in the detergent tray will indicate that you’re being a bit too generous with your cleaning solution. Properly stacked dishes – are your dishes stacked properly? Overloading or poor stacking could be at the root of the problem. Make sure you don’t cram too much into the machine, and that all items are stacked properly in the trays.
Door seal – is the seal around the door old and worn? If so, check your owner’s manual to find out the correct part number for a replacement seal.
Pipe connections – make sure that the pipe connections at the back of your machine are in good condition and fastened correctly. In the worst case scenario your machine might have corroded at the bottom, in which case the only solution is to replace your dishwasher.
- Not Filling
If your dishes are coming out dry and dirty then your machine is not filling with water. Check under the sink and make sure the hot water stop valve is fully open. If it is, check your owner’s manual to see whether you can access the water inlet valve; this might be clogged up with debris and need clearing out.
If you’re still having some trouble with your machine, we recommend calling in a professional appliance engineer.
- Not draining
A little water left in the tub is normal, but if you’re worried about the amount of water left after each wash then check the following:
- Is your drain hose damaged?
Are your drains blocked?
If neither of these applies then you might need a new pump. Check your owner’s manual for advice on replacing your dishwasher’s pump assembly.
- Not Washing
If your plates are still dirty after a wash cycle then there’s a good chance that poor loading is the culprit.
When stacking your dirty dishes make sure you don’t just pile them into the machine. Plates may be in the way of others, meaning that the water and detergent just won’t reach them.
If the problem continues you can try adding more detergent, but if that doesn’t do the trick it’s time to pick up the phone and have a chat with an expert appliance engineer.
- Not taking the detergent
You may be putting in too much of the soapy stuff. Your dishwasher will only use the amount needed to clean the plates inside it. Use less detergent for a couple of runs and see if that helps.
- Water is cold
If you suspect the water is not heating properly:
Hold a thermometer under the hot water tap for two minutes.
Check that the water is at least 140 degrees Fahrenheit (60 degrees Celsius).
If it’s not hot enough then turn up the dial on your hot water heater.
- Excessive Noise
There are a number of factors that can result in your machine being a bit too noisy. There may be some loose or worn parts, or you could just be stacking your plates badly.
When the machine is cold, look around the inside for any hard objects such as bones, fruit stones or errant knives and forks and remove these from the machine.
Make sure the unit is on a level surface. If the noise is a ‘thump’ then your water inlet valve may be in need of replacement.
