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.
