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 them.
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.
