Why causes my dryer to not heat up?

by Arlene Pellegrin Last activity date:

I have an Amana Commercial Quality Electric Dryer, Model #ALE443RAW. It stopped heating. I replaced the heating element, but this does not solve my problem. Is there something else that would cause it not to heat?

The first issue that I recommend checking is your house circuit breakers or fuses for the dryer outlet. Here is a brief video that covers that issue:

Video: Dryer Won't Heat

. That basic troubleshooting step should no be overlooked.

If the house circuit breakers or fuses for the dryer are okay, I recommend that you carefully check the voltage at the outlet using a volt/ohm meter. The first image below shows the voltage that should be measured at that dryer outlet.

NOTE: You should only check this live outlet voltage if you completely confident in your technical ability to safely measure it. Wear proper safety equipment (insulated rubber electrical safety gloves and protective goggles) when making this voltage check

. If you are not comfortable with checking that live voltage, I recommend that you skip this step or have a technician check it if necessary. Here is a link for the Sears Service website in case you need it:

If the voltage supply to the dryer is good, you could have a wiring failure in the circuit or a failed component. The second image shows that heating circuit. The L1 leg of power is trace in red and the L2 circuit is traced in green. The most suspect component in that circuit is your thermal fuse (Key 4 on the third image). I recommend that you

unplug the dryer

and check that component first. Here is a link for a brief repair video that shows how to test that thermal fuse:

Video: Thermal Fuse Testing

. If that fuse is blown, it will need to be replaced. You can order that part from the

Sears PartsDirect

website. The part number for that fuse is 40113801. Here is a direct link for that part:

Thermal Fuse

. Be sure that you

unplug the dryer

to disconnect electrical power before accessing internal components and replacing that fuse. NOTE: If that thermal fuse was blown, be sure that you check the exhaust vent duct system to the outside of your home for a restriction as shown in that video. Also, stopping the dryer in the middle of a heated cycle can cause that thermal fuse to blow. Run the dryer without heat for a few minutes before opening the door to stop the dryer in the middle of a cycle to help prevent that type of problem.

If the thermal fuse is okay, you could have a wiring failure or another component in that heater circuit that has failed. You may be able to use that wiring diagram and the access information in the 4th image to check more components. Be sure that you

unplug the dryer

before accessing internal components. If you need more help, reply with additional details and we will assist you further.
