Troubleshoot An Electric Dryer That Won’t Heat With These 5 – Steps

Step-1. Breaker

The first thing to troubleshoot if your electric dryer won’t heat is the dryers 220 circuit breaker located in the main circuit breaker box.  You will need to locate the breaker box and find the 220 breaker that is dedicated for your dryer.  Flip the breaker off and on a few times, even if it looks like the breaker looks like it is already in the on position.  The electric clothes dryer runs on 220 and if half of the two pole breaker is tripped the dryer motor will run on 110 but the heating element will not heat.  If your clothes dryer still won’t heat up, further troubleshooting will need to be performed.

Step-2. Thermal Fuse

The dryer thermal fuse is also known as the thermal cutoff fuse and the temperature fuse.  The fuse is used as a safety mechanism, cutting off electricity to the dryer motor and the heating element to keep the clothes dryer from getting too hot.  Note – Once this fuse has blown it cannot be reused. If your fuse has blown, you will need to check for blockage or lint build up in the clothes dryer vent hose or ventilation system, before installing a new thermal fuse, only to have it blow again.

Step-3. Heating Element

The heating element is used to heat the air before it enters the drum on an electric clothes dryer.  If your electric dryer is not heating, you will need to visually inspect the element for damage.  If the element coils are intact and no signs of damage are found, you will need to test it for continuity using a multimeter.  If the element does not have continuity the part is bad and will need to be replaced.  Before installing the new heating element, you will need to check for loose or burnt wires and repair them before connecting them to the new element.  Loose wire connections and burnt or damaged wires can short out the new element.

Step-4. Cycling Thermostat

The cycling thermostat is normally located on the clothes dryers blower housing.  It is used to cycle the heating element off and on during the drying cycle to regulate the temperature of the air entering the dryer.  Using a multimeter, you will need to test the cycling thermostat to see if it has continuity, if the test shows that it does have continuity the thermostat is good.  If the thermostat does not have any continuity, then the part is bad and will need to be replaced.

Step-5. High-Limit Thermostat

The high-limit thermostat is located on the clothes dryers heating element housing.  It is used to monitor the dryers temperature, and will shut the heating element off if the dryer gets too hot.  You will need to test the thermostat to make sure that it has continuity using a multimeter, if the thermostat has continuity the part is good.  If the thermostat does not have continuity, the part is bad and will need to be replaced with a new one.
