That’s usually the door switches. The manufacturer made a service kit for this series for similar issues, part # W11244490. When replacing these switches make sure you take pictures of the wiring on the original switches before disconnecting anything from them and try to do 1 to 1 swaps if possible. This kit has 4 switches, if your model has 3 when you get in there just hit me up on this thread and I’ll help you get it wired correctly, older models had 3 and the manufacturer added that 4th switch later on and the kit retrofits the older ones to the 4 switch style.

I have a 3 switch model WMH73521CS-3. Ordered the W11244490 4 switch kit, not sure it will come with the instructions to convert to the 4 switch arrangement. How is the 3 switch wiring changed to the 4 switch units?

This goes over the conversion.
