4.89 (64)
By: Whirlpool
Part Number: OEM18024936
Manufacturer Part Number: WP3390719

The Thermal Fuse is an OEM part for Whirlpool dryers. It is a critical safety component designed to protect the dryer from overheating by blowing and cutting off power if the temperature exceeds safe limits. This disposable, one-time fuse is essential for preventing potential fire hazards and ensuring the appliance operates within safe temperatures.

Symptoms of a bad Thermal Fuse include:

  • The dryer not starting or suddenly stopping during a cycle
  • No heat being produced while the dryer is running
  • Unexplained cessation of all dryer functions

Causes of a bad thermal fuse can stem from restricted airflow due to lint buildup, a malfunctioning heating element that causes excessive temperatures, or other electrical issues within the dryer.

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

Answer

Hello Terra. The thermal fuse WP3390719 should read closed for continuity. If it were bad, the dryer would not run. Check and make sure you have 240 volts coming to the dryer. Check and make sure the unit is not set to Air Fluff. You will need to test both wires going to the heater (isolated) and see where your loosing power at. You will trace the wire that is dead and see if it is the motor 279787 or the timer WP8299771. You can test these with a multi-meter MA-DM1. They should read closed for continuity. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
