How to replace a wall oven thermal fuse
This wall oven repair guide explains how to replace a wall oven thermal fuse. The fuse trips to protect the wall oven from excessive heating. If the wall oven thermal fuse blows, the oven won't heat. You can reset some fuses with the press of a button; this guide explains how to replace one that can't be reset. Replace the oven thermal fuse using a manufacturer-approved replacement part.
The self-cleaning cycle sometimes causes the wall oven thermal fuse to trip; if it trips when the oven isn't self-cleaning, investigate what caused the oven to overheat before using the oven again.
Follow these basic repair steps to replace the thermal fuse in Kenmore, Frigidaire, Whirlpool, KitchenAid, Electrolux, Maytag and Amana wall ovens.
Instructions
- 01.
Disconnect electrical power
Shut off the house circuit breakers for the wall oven to completely disconnect electrical power.

Remove the wall oven from the cabinet
Set a sturdy work table or platform just in front of the oven and pad the surface of the table with a towel or cardboard to protect the table.
Open the oven door and remove the mounting screws that secure the oven to the sides of the oven cabinet. Slide the oven forward in the cabinet. You should have enough slack in the electrical conduit of the power supply; if not disconnect the power supply wiring from the junction box for the wall oven.
With someone's help, carefully lift the oven out of the cabinet and set it on the table in front of the cabinet.
Tip: Use the installation manual for your wall oven to guide you in this step.
