By: Whirlpool
Part Number: OEM18028221
Manufacturer Part Number: WP4451042

The Thermal Fuse is an OEM part for Whirlpool ovens. It is designed to monitor the oven's temperature and automatically cut off power to the heating elements if the temperature exceeds a certain threshold. It acts as a failsafe to prevent excessive heat buildup and potential damage to the oven or surrounding areas.

Causes of a faulty oven thermal fuse can include a power surge, overheating, or electrical component failure. These factors can result in the thermal fuse blowing; interrupting the power supply to the heating elements and preventing further operation of the oven.

Symptoms of a bad oven thermal fuse may include:

  • Oven not heating up at all
  • Error codes or error messages displayed on the oven's control panel
  • Oven appears to be powered off

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.
For the 248F thermal fuse with the insulated female spade and plug order WP4456654.
