15 Common Whirlpool Dryer Problems and How to Fix Them

9 Reasons Why a Whirlpool Dryer Doesn’t Start

8 Reasons Why Your Whirlpool Dryer Won’t Spin

1. Faulty Heating Element

A common issue with Whirlpool dryers is a faulty heating element, which can cause them to stop producing heat. To diagnose this problem:

  • Unplug the dryer and locate the heating element at the back.
  • Inspect for visible damage like breaks or burn marks.

Test continuity with a multimeter:

  • A reading close to zero ohms indicates it’s working.
  • An infinity reading or no reading means it’s failed.

Replacing the heating element requires technical skills. If unsure, seek professional help. Visually inspecting and testing with a multimeter can help diagnose and address issues with Whirlpool dryer heating.

2. Thermal Fuse Issues

  • A common problem with Whirlpool dryers not heating is a faulty thermal fuse, a safety device that prevents overheating.
  • Factors like clogged ventilation or electrical issues can cause thermal fuse failure.
  • Blown thermal fuse disrupts power to the dryer’s heating component, causing it to stop producing heat.

Steps to Fix

  1. Use a multimeter to test continuity; absence indicates blown fuse.
  2. Locate and access the thermal fuse near the blower housing or heat source assembly.
  3. Disconnect power, remove necessary parts, and detach wires from the faulty fuse.
  4. Replace with a new fuse matching Whirlpool model specifications, following manufacturer guidelines.
  5. Reassemble parts, reconnect power, and test dryer to ensure proper heating.

3. Faulty High-Limit Thermostat

When Whirlpool dryers fail to heat, a common culprit is a faulty high-limit thermostat, a safety device monitoring internal temperature. Troubleshoot using a multimeter to test continuity. Gas dryers may also face issues with gas valve solenoids, affecting heat production.

High-Limit Thermostat

  • Acts as a safety device to prevent overheating.
  • Test for continuity with a multimeter; replace if defective.

Gas Valve Solenoids

  • Control gas flow for ignition and heat.
  • Check for proper function and replace if faulty.

Ensure gas supply to the dryer is adequate and follow safety precautions when attempting repairs. Addressing these issues restores efficient heating in Whirlpool dryers without professional assistance.

4. Malfunctioning Cycling Thermostat

A malfunctioning cycling thermostat can cause a Whirlpool dryer to stop heating properly. This thermostat regulates the dryer drum’s temperature by controlling the heating element. If it’s faulty, it may fail to activate the heating element, resulting in no heat production. Common issues include getting stuck open or closed, leading to either no heat or overheating.

  • Start by unplugging the dryer and accessing the cycling thermostat in the control panel.
  • Inspect it for visible damage like burning or corrosion.
  • If damaged, replace it with a new one suitable for your dryer model.
  • Use a multimeter to test its functionality if no visible damage is present.

When troubleshooting Whirlpool dryer heating issues, ensure caution and proper tools. Consulting a repair professional is recommended if unsure about DIY fixes. Addressing problems with cycling thermostats restores proper heat circulation, ensuring efficient drying performance.

5. Igniter Problems (Gas Dryers)

Gas dryers rely on an igniter to create heat for drying clothes. Igniter issues are common reasons for a Whirlpool dryer not heating properly.

  • Igniter may wear out or become damaged over time.
  • Faulty igniter may fail to glow or ignite due to broken filament or loose connection.
  • Replacing the faulty igniter is usually necessary for restoring proper heating functionality.

Using a multimeter to test continuity can diagnose igniter problems. No continuity reading indicates igniter defect, necessitating replacement. Caution is essential when handling gas components; seek professional assistance if unsure.

6. Defective Gas Valve Solenoid (Gas Dryers)

A common reason for a Whirlpool gas dryer’s inadequate heating is faulty gas valve solenoids. These components regulate gas flow to the burner assembly, and when defective, they hinder heat production. Here’s how to troubleshoot and address this issue:

DIY Fixes

  • Unplug the dryer and shut off the gas supply.
  • Access the burner assembly and locate the gas valve solenoids.
  • Test solenoids with a multimeter for continuity.
  • If defective, order replacements and install following manufacturer instructions.

Maintenance Tips

  • Regularly clean lint traps and dryer vents to prevent airflow blockages.
  • Check the high-limit thermostat for proper function and replace if needed.

Identifying and fixing issues like faulty gas valve solenoids can restore your Whirlpool dryer’s heating efficiency. Additionally, routine maintenance helps prevent future problems and extends the appliance’s lifespan. If unsure, seek professional assistance for repairs involving gas appliances.

7. Broken Radiant Flame Sensor (Gas Dryers)

A broken radiant flame sensor can cause a Whirlpool gas dryer to not heat properly, affecting its performance. This sensor regulates gas flow to the burner assembly by detecting heat from the igniter.

  • Crucial role in regulating gas flow.
  • Detects heat from the igniter to ignite the burner and produce heat.
  • Malfunctioning sensor leads to insufficient heat generation.

To troubleshoot, use a multimeter to check for continuity and resistance in the sensor’s electrical circuit. Disconnect power, locate the sensor near the burner assembly, and test for continuity using the multimeter. If there’s no continuity or an open circuit reading, replace the sensor.

  • Use multimeter to check continuity.
  • Disconnect power and locate sensor near burner assembly.
  • If no continuity or open circuit, replace sensor.

Replacing the sensor involves disconnecting wires and removing mounting screws. Consult the dryer’s manual or seek professional help if needed. Regular maintenance like cleaning lint filters and ensuring proper ventilation can prevent heating issues.

  • Replace sensor by disconnecting wires and removing screws.
  • Regular maintenance prevents heating issues.
  • Clean lint filters and ensure proper ventilation.

8. Issues with the Ignition Coils (Gas Dryers)

When a Whirlpool gas dryer isn’t heating, a common culprit is faulty ignition coils responsible for igniting the gas. These coils can wear out over time, leading to weak sparks or no ignition at all.

  • Ignition coils ignite gas to produce heat in Whirlpool dryers.
  • Wear and tear over time can cause weak sparks or failure to ignite.
  • Weak flame or inconsistent heating may indicate ignition coil issues.

To diagnose, use a multimeter to test the igniter and gas valve solenoids for continuity. If either component lacks continuity, replacement is necessary. Regular maintenance, like cleaning lint traps and checking for clogged vents, can prevent ignition coil issues.

9. Electrical Problems

Electrical issues often lead to heating problems in Whirlpool dryers. Faulty power cords or outlets can disrupt electricity flow, causing heat inconsistency. Tripped circuit breakers or blown fuses can also interrupt power supply to heating elements. Loose or damaged wiring connections further exacerbate heating issues.

  • Faulty power cords or outlets can disrupt electricity flow.
  • Tripped circuit breakers or blown fuses interrupt power supply to heating elements.
  • Loose or damaged wiring connections compromise effective electricity transmission.

To troubleshoot, unplug the dryer and inspect wiring connections for damage or looseness. Secure connections if necessary. If issues persist, consult a professional electrician for further diagnostics and repairs. Prompt attention to electrical problems minimizes downtime due to heating disruptions in Whirlpool dryers.

10. Clogged Ventilation System

A clogged ventilation system is a common issue that can hinder a Whirlpool dryer’s heating efficiency. Lint and debris accumulation restrict airflow, leading to poor drying performance and potential overheating. To diagnose and address this problem:

  • Check the lint screen for buildup, indicating blockage.
  • Inspect the outside exhaust vent for obstructions like nests or leaves.
  • Disconnect the dryer, locate the vent hose, and clear accumulated lint using a vacuum or brush.
  • Pay attention to bends where lint accumulates more and clean thoroughly.
  • Reconnect hoses and power up the dryer after ensuring all connections are secure.
