Why Isn’t My Dryer Heating Up? 5 Areas To Check on Your Dryer.


If your dryer isn’t heating up like it used to, there are 5 areas to check.

  1. Proper Voltage
  2. Heating Element
  3. Thermal Fuse
  4. Thermostat
  5. Timer Motor

Proper Voltage: There are three ways to see if the proper amount of power is making it to your dryer.

(1) Making sure the dryer is properly plugged in.
(2) Check the circuit breaker to see if all the breakers are correct.
(3) Check for fuses in your fuse panel.

Heating Element: Once your heating element breaks, it is not fixable and will need to be replaced. It is possible to test your heating element by setting your multi-meter to the Rx1 resistance scale. Take each probe and place it at the end of the element.  If the results come back with infinite resistance, you will need to replace your heating element.

Thermal Fuse: Like the heating element, the thermal fuse is not repairable and will need to be replaced if it is broken. You will have to test the thermal fuse to see if it is working properly. To test the fuse, remove the wires that are leading to the thermal fuse. Take your multi-meter again and set it to the Rx1 setting. For best results, test the thermal fuse at room temperature, resulting in a reading of zero. If you test the thermal fuse when it is heated, a reading of infinity will be produced.

Thermostat: Dryers contain many thermostats to help control the internal temperature. Dryer thermostats are about an inch and a half long, oval shaped, and are connected to two wires. Remove these wires and use your multi-meter to test the thermostats. There should be results of either zero or infinity. If you do not receive either of these results, you need to replace the component.

Timer Motor: The dryer’s timer motor regulates the length of time that power is directed at each component. To find the motor, find the timer assembly. They are located behind the control console panel. Remove the wires from the motor. Set the ohmmeter to the Rx1 setting. A proper reading for dryers falls in the 2000 to 3000 ohms range. A proper reading can be found in the dryer’s owner manual.
