Whirlpool Dryer Thermostat Not Working — Causes & Repair Parts
Whirlpool dryer showing thermostat not working? Here are the 5 most common causes, how to diagnose each, and 10 OEM-compatible repair parts available with fast US shipping.
Common Causes of Thermostat Not Working in Whirlpool Dryers
- Heating element burned out (electric): The heating element coil breaks open and stops producing heat. Most common dryer repair.
- Thermal fuse blown: A blown thermal fuse interrupts the heating circuit even if the dryer drum turns.
- Gas valve solenoid failure (gas dryers): The solenoid valve opens to allow gas flow. Failed solenoids prevent ignition.
- Igniter failure (gas dryers): The igniter glows red-hot to light the gas. A cracked or dead igniter stops heat production.
- Cycling thermostat defective: The cycling thermostat regulates drum temperature. An open thermostat kills the heat circuit.
How to Diagnose Your Whirlpool Dryer
- Unplug the dryer before any inspection — electric dryers use 240V, which is lethal.
- Check and clean the lint trap — should be done after every load to maintain airflow.
- Inspect the exhaust duct from the dryer to the exterior vent for kinks, blockages, or crushed sections.
- Test the thermal fuse with a multimeter for continuity — a blown fuse reads open circuit and must be replaced.
- Test the door switch: open the door, press the plunger with your finger, and listen for a click.
- Check the drive belt by opening the cabinet — a broken belt will be visible inside the drum area.
- For gas dryers: verify the gas supply is on and igniter glows orange within 30 seconds of starting.
