Parts That Fix Whirlpool Dryer WED8300SW2 Too hot

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 is the moisture sensor for your dryer. It helps detect the amount of moisture in your clothes during the dryer cycle. If you notice your clothes are still wet after an automatic dryer cycle is done, you may need to replace the sensor. You will find the moisture sensor behind the lint screen. Be sure to disconnect the power source from the dryer before you begin this repair. Note: Some model's require two sensors, please order quantity needed. Sensor only, harness is not included. This part is sold individually.

When connected to electricity the dryer heating element glows red hot and generates heat. When air is blown over it, it heats the air which is used to dry the clothes. The heating element fits inside the heater housing inside the dryer. Wear and tear on the heater coil from use will eventually cause the coil to break and the element to fail. When this part fails it can cease to produce any heat. Alternately, the coil could break and short to ground allowing the dryer to continue to heat even when turned off. The latter is a fire hazard and the dryer should be disconnected from power until the element is replaced. If the element coil breaks, the element needs to be replaced. This model is 11 by 5 inches with 5/16” terminals, metal and ceramic, and comes in black. It is sold individually.

This hi-limit thermostat acts as as safety mechanism that keeps the dryer from overheating. Once the dryer temperature reaches a certain point, this piece will shut down power to the heating element.
