The Dryer Thermal Fuse (Thermal Cutoff, Temperature Fuse) is a 2 by ½ inch, white, plastic safety mechanism that stops the flow of electricity to the motor circuit when a dryer overheats. If the fuse is missing or broken, your dryer will not start. A thermal fuse fails when the exhaust temperature exceeds the fuse rating, that is when the temperature rises above the temperature that the fuse is designed to handle. This can occur when a heating element is shorted, a regulating thermostat or thermister fails, or with a partially restricted exhaust vent. The fuse attaches to the blower wheel housing. It must be replaced when there is no longer continuity between the terminals. This is a one-time fuse, meaning it cannot be re-set. The replacement part features two 3/16 inch terminals.
The internal-bias thermistor (Thermistor, Dryer Thermister, Dryer Thermistor) prevents the dryer from overheating by monitoring and controlling the temperature of the inside of the dryer drum. It is located on the blower housing, next to the thermal fuse. If your thermistor is defective, drying time could be prolonged or you could get a fault code. You could also notice your dryer overheating. You can test the outlet thermistor on a multimeter, it should read 10Kohms (10,000 ohms) of resistance at room temperature. It can tolerate 10% fluctuation. If your reading indicates the part is defective, it will need to be replaced. This model is white plastic. It is sold individually.
Also known as Thermal Cut-Off kit. The thermostat acts as a safety mechanism that keeps the dryer from overheating and the fuse is like a backup system - it's set to trip at a higher temperature than the thermostat. Once it trips, it has to be replaced.
This kit is used for electric clothes dryers, and it comes with a yellow wire nut.
