A thermal fuse is used when the overheating is a result of a rare occurrence, such as failure requiring repair (which would also replace the fuse) or replacement at the end of service life. Some flasher bulbs interrupt power when heated, while other twinkle/sparkle mini-bulbs momentarily shunt current around the filament. [citation needed]. Some thermal switches must be reset manually after they have been tripped. Thermal fuses do not reset themselves when the temperature drops like a circuit breaker would. Thermal fuses are used widely in all sorts of industrial applications. They are found in virtually every refrigerator, microwave, clothes dryer, space heater, and many more appliances found throughout the home. If the wall oven thermal fuse blows, the oven won't heat. Unlike a thermal switch which may automatically reset itself when the temperature drops, the thermal fuse is more like an electrical fuse: a single-use device that cannot be reset and must be replaced when it fails or is triggered. A cable limiter is similar to a fuse but is intended only for protection of low voltage power cables. Most of the electrical appliances use thermal fuses. Read that carefully, and it will help you determine if the fuse is broken or not. All information is provided "AS IS." If the thermal fuse is located behind the rear panel, remove the screws with the screwdriver.
