The Thermal Fuse is an OEM part for Whirlpool dryers. This safety device protects the dryer from overheating by cutting off power if the dryer exceeds a certain temperature. It is crucial for maintaining safe operation and preventing potential fire hazards. This thermal fuse has 1/4-inch terminals and operates around 243 degrees F. 

Causes of a bad thermal fuse include lint buildup causing overheating, blocked ventilation, or a malfunctioning thermostat. These issues can lead to the fuse blowing to prevent further damage or risk.

Symptoms of a bad thermal fuse include:

  • Dryer not starting
  • No heat in the dryer
  • Dryer shutting off mid-cycle
  • The dryer running but not heating

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

Questions & Answers

For Whirlpool Thermal Fuse (Part Number: OEM18022719)

1 Answer

Honoree, Yes, If the heater element shorted, and the thermal fuse on the heater housing assembly WP307473 has an open circuit, the dryer will still not heat, you need to check or replace the thermal fuse as the next logical step. Good Luck.

Hello Rodney. First you will want to make sure that you are getting 240V to the unit by testing the outer outlet prongs or the terminal box on the dryer. If you are getting 240V you could have a defective element WPY308612 or a open thermostat WP3387137, WP303396. You will need a multi meter MA-DM1 to test. Here is a link you can refer to for help with using a multi meter: http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html . Thanks!
