How To Replace A Whirlpool Wall Oven Thermal Fuse: A Step-by-step Guide For Diyers

If your Whirlpool wall oven is not heating properly, the thermal fuse may be blown. A thermal fuse is a safety device that prevents the oven from overheating. It is a small, cylindrical device that is located near the heating element. When the oven reaches a certain temperature, the thermal fuse blows, interrupting the flow of electricity to the heating element. This prevents the oven from getting too hot and causing a fire. Replacing a thermal fuse is a relatively simple repair that can be done by most do-it-yourselfers.
