Investigate these five areas if your dryer is not heating up:
If your dryer won't heat up, it's possible that it is not being
supplied with the proper voltage. Here are three ways to make sure
power is getting to your dryer: First, make sure your dryer is plugged
in. Next, check the circuit breaker panel to make sure all the circuit
breakers are in the correct positions. Finally, check to make sure no
fuses in your fuse panel are blown. Any of these could explain why
power is not getting to your dryer.
It is possible that your dryer isn't heating because its heating
element is defective. Heating elements are irrepairable. If yours has
ceased to function properly, you will have to replace it. Open your
dryer's cabinet and locate the heating element so that you can test it.
Another possible cause for a dryer not heating up could be attributed
to a faulty thermal fuse. Once a dryer's thermal fuse has blown, it is
no longer of any use. If your dryer's fuse is blown, you will have to
replace it. Open up your dryer's cabinet and locate its thermal fuse so
that you can test it.
If any of your dryer's thermostats have become defective, they could be
the reason that your dryer is not heating. Open up your dryer's cabinet
and test each of your dryer's thermostats. If any are faulty, replace
A defective timer motor could also cause your dryer to not heat up.
Test your dryer's timer motor. If it is no longer functioning as it
should, replace either the entire motor assembly, or just its motor.
