Dryer is Too Hot

The part(s) or condition(s) listed below for the symptom Dryer is too hot are ordered from most likely to least likely to occur. Check or test each item, starting with the items at the top of the page.

Heating Element

The heating element warms the air before the air enters the dryer drum. If the element is partially shorted out, it may produce heat continuously, even if the dryer has reached the proper temperature. When this happens, the dryer gets too hot. To determine if the heating element is at fault, use a multimeter to test each terminal for continuity to the case. If the heating element has continuity to the case, it is shorted out. If the heating element is shorted out, replace it.

Heating Element Assembly

The heating element warms air as it passes over the element. If the element is partially shorted out, it may produce heat continuously, even if the dryer has reached the proper temperature. When this happens, the dryer gets too hot. To determine if the heating element is at fault, first use a multimeter to test the heating element for continuity. If the heating element does not have continuity, replace it. Next, test for continuity from each terminal to the case. If the heating element has continuity to the case, it is shorted out. If the heating element is shorted out, replace it.

Air Flow Problem

If the vent is clogged or partially clogged, it will restrict the airflow through the dryer, substantially increasing the drying time. To ensure proper dryer performance, you should clean your dryer?s venting system at least once per year.

Cycling Thermostat

The cycling thermostat cycles the heat on and off to maintain the proper air temperature. If the thermostat is defective, it may keep the heat on too long, causing the dryer to get too hot. However, this is rarely the case. Before replacing the cycling thermostat check all the more commonly defective parts. If you have determined that all of the other components are working properly, test the thermostat by using a multimeter to test it for continuity. If the thermostat does not have continuity, replace it.

Cycling Thermistor

The cycling thermistor tell a board to cycle the heat on and off to maintain the proper air temperature. If the thermistor is defective, it may keep the heat on too long, causing the dryer to get too hot. However, this is rarely the case. Before replacing the cycling thermistor check all the more commonly defective parts. If you have determined that all of the other components are working properly, test the thermistor by using a multimeter to test it for continuity. If the thermostat does not have continuity, replace it or if it out of it's ohm normal range, replace it.

Felt Seal

Most dryers have a felt seal at the front and rear of the drum to prevent heat from escaping the drum. If the seal is worn out or missing, the heat will not be drawn through the drum properly, causing the dryer to get too hot. Check the drum seal to ensure that it is creating a reliable seal around the drum. However, this is rarely the case. Before replacing the felt seal check all the more commonly defective parts. If you have determined that all of the other components are working properly, replace the felt seal.

Blower Wheel

The blower wheel works with the drive motor to draw air into the dryer drum. Clumps of lint, socks, and small articles of clothing can escape the lint filter and get caught in the blower wheel. In addition, the blower wheel sleeve can wear out, allowing the blower wheel to wobble on the motor shaft. If the blower wheel is obstructed or defective, the dryer may get too hot. To determine if the blower wheel is working properly, remove the dryer vent and assess the strength of the air flow. If the air flow is weak, check the blower wheel for obstructions. If no obstructions are present, try rotating the blower wheel by hand. If the blower wheel wobbles as it turns, replace it.
