How to Test & Replace Parts - Dryer Not Heating

This page was created to show you how to test and replace the parts on your dryer.  It doesn’t cover every dryer part (yet), but it will give you the knowledge to test and replace parts that aren’t even listed below.

If you can figure out how to disassemble your dryer, you can access these parts.

To help you find the right part number for your dryer there are search boxes on this page, just insert your model number, click search, and find your part.  Our sponser offers a 365 day return policy on all parts.

Gas Valve Coil/Solenoid Test

Valve coils can be tested by measuring the resistance between the posts on the coil, however it isn’t always accurate.  I’ve found the best way to test the valve coils is by watching them.  Most Whirlpool dryers have a small window or lower panel that can be removed so you can observe the dryer during the heating cycle.  If the coils don’t stay on for long periods of time, either there is lint build up in the venting or the valve coils are bad.  When I sell a used dryer, I always replace the valve coils because they are one of the first parts to fail on gas dryers.
