What Are Possible Reasons a Dryer Would Not Be Heating?

There are many issues that may prevent a dryer from heating properly, such as improper voltage, a defective heating element, a thermal fuse, a faulty thermostat or a defective timer motor. The first thing to check is that the dryer is receiving the correct amount of power.

When troubleshooting a dryer that does not heat, it is important to first be sure that the dryer is receiving the correct voltage. Make sure that the dryer is plugged in and its circuit breaker is in the correct position. Make sure that no fuses in the fuse panel are blown.

Next, test the dryer's heating element. You need to open the dryer's cabinet and locate the heating element in order to make sure that it is working properly (check the dryer's instruction manual to determine how to open the cabinet). If the heating element is defective it must be replaced. Check the dryer's thermal fuse, also located inside the cabinet, and replace it if it is blown.

A defective timer motor prevents a dryer from heating up as well. Test the timer motor to ensure that it is performing correctly. If the timer motor is malfunctioning, either the motor or the entire motor assembly needs to be replaced. Timer motors are much less expensive than purchasing an entire motor assembly.
