Whirlpool Duet Dryer not Heating – 7 Solutions!

Spread the love

Whirlpool manufactures a variety of dryers, including electric, gas, front-loading, and top-loading models.

If your dryer is heating slowly, it is almost certainly due to a lint blockage. If the dryer does not heat at all, the fault is most likely with the heating element or thermal fuse, which should be tested with a multimeter and replaced if found to be faulty.

This guide contains instructions and additional possible causes for your Whirlpool dryer not heating.

When the dryer stops heating, the first thing to check is the circuit breaker panel or fuse box. An electric dryer is equipped with two circuit breakers, one for heating and another for power.

Occasionally, the breaker for heating is tripped, resulting in the dryer running but not heating.

Conduct a visual inspection of your electrical panel for tripped circuit breakers or blown fuses.
Reset any circuit breakers that have been tripped and replace any blown fuses.

Additionally, the dryer’s breakers can be checked with a multimeter to ensure that each circuit is supplying the 120 volts (110 volts on some models) required for proper operation.

  • ABSENCE OF GAS

If you have a Whirlpool gas dryer, verify that the gas is turned on and properly connected.

  • BLOCKING OF THE LINT SCREEN

If your Whirlpool dryer continues to heat but at a slow rate and is generally inefficient at drying your clothes, cleaning the lint screen may resolve the heating issue.

When the lint screen is clogged, the moisture in the air is trapped in the dryer drum for an extended period of time, resulting in the dryer taking longer to dry your clothes.

A clogged lint screen can also cause lint to accumulate in other areas of your dryer, so empty it regularly.

  • Remove the lint screen and wash it in warm soapy water in the sink.
  • While the screen is drying, insert a vacuum attachment into the slot that the lint screen is designed to fit into.

Reinstall the lint screen.

  • BLOCKAGE OF VENTILATION

As with the lint trap, if the ventilation is obstructed, it will take longer for your clothes to dry.

Additionally, there is a greater risk of lint damaging other components of your dryer. If you have access to the exterior vent, you can verify that the ventilation system is operating properly by observing a warm, consistent airflow.

Cleaning the ventilation improves the heating performance of your dryer and reduces the risk of a fire starting as a result of a lint blockage.

  • Disconnect the dryer’s power supply. Turn off the gas supply to your dryer if it is a gas dryer.
  • Remove the ventilation hose from the dryer’s rear by removing the metal tape, unscrewing or unclipping it. Eliminating the panel that surrounds the ventilation area may improve access to this area.
  • Clean the ventilation hose and surrounding area.
  • Utilize a ventilation cleaning kit, vacuum attachment, or leaf blower to thoroughly clean the ventilation duct.

Reattach the ventilation hose to the dryer, being careful not to kink it and allowing air to flow freely through it.

  • MANUFACTURER’S DEFECTIVE HEATING ELEMENT (ELECTRIC DRYERS)

If your Whirlpool dryer does not heat at all, one of the most common causes is a heating element malfunction.

A heating element is made up of a coil of wire contained within a metal chamber. If the coil fails, the heating element will cease to function and must be replaced.

  • Disconnect the dryer from the electrical outlet.
  • Consult your dryer’s owner’s manual to determine the location of the heating element. Depending on the model, the front or rear access panel will need to be removed.
  • Inspect the heating element for burn marks or coil breakage. If the coil becomes damaged, the heating element must be replaced.

Conduct a continuity test on the heating element using a multimeter. If the multimeter test indicates that the heating element is defective, it must be replaced.

  • BURNED OUT THERMAL FUSE

If the heating element is functioning properly, another frequent cause of a Whirlpool dryer not heating is a blown thermal fuse.

The thermal fuse is a fire-retardant device installed in your dryer to prevent it from catching fire. When the dryer temperature reaches a preset level, the thermal fuse is tripped, and the dryer ceases to operate.

The dryer may continue to operate but without producing heat on older models. If you determine that the thermal fuse is to blame, you must determine what caused it to blow and resolve the issue.

  • Disconnect the dryer’s power supply. Turn off the gas supply to your dryer if it is a gas dryer.
    Consult your dryer’s owner’s manual to determine the location of the thermal fuse.
  • Depending on the model, either the top, front, or rear access panel will need to be removed.
  • Locate and remove the thermal fuse, which is typically located on the blower housing or near the dryer’s heat source.
  • Using a multimeter, check the thermal fuse for continuity.

Substitute a new thermal fuse for a faulty one.

  • GAS VALVE SOLENOID DEFECTIVE

Gas dryers have two or more solenoid coils for the gas valve. The coils allow gas to flow into the burner assembly. A faulty gas valve solenoid prevents the dryer from heating.

As with an electric dryer, a multimeter can be used to inspect and test the coils of a gas dryer to determine if they are defective.

Additionally, the igniter can be checked to see if it glows and then goes out, indicating that the gas valve solenoid is defective.

  • Disconnect the dryer’s power supply.
  • Turn off the dryer’s gas supply.
  • Locate the gas valve solenoid by consulting the owner’s manual for your dryer. Eliminate the corresponding access panel.
  • Coils from the gas valve solenoid should be removed.
  • Conduct a continuity test on the coils using a multimeter.
  • Replace any coils that are defective.

ADDITIONAL POSSIBLE REASONS

After ruling out the causes listed above, a problem with one of the following components may also contribute to your Whirlpool dryer not heating properly.

Each component should be tested with a multimeter and, if found to be defective, should be replaced. Before accessing the parts, disconnect the dryer from the power source and turn off the gas.

  • Igniter for Cycling Thermostats with a High-Limit Thermostat (Gas Dryers)
  • Timer with flame sensor (for gas dryers)
