FIXED DV40J3000EW/A2: all components on heating element checked out but I replaced everything anyway. Dryer gets proper voltage.

Dryer has been very reliable. 3 loads after replacing the belt, tensioner and rollers, it stopped heating up. Pulled the wiring harness from motor and have a burnt terminal to the heating element; the wire has continuity to the heating element. Do I need to replace the motor?

Where is the burnt terminal? At the motor itself?

Take a photo of it and upload it here please.

thanks for responding Jake. Yes it's burnt at the terminal on the wiring harness. the wire still has connectivity end to end but don't know how to test the switch heater circuit. I cleaned it up and reconnected and reassembled the unit not still now heat. I believe the contact is burnt inside and not switching on the heating element. I couldn't find a new switch heater circuit so I went ahead and ordered a new motor with the circuit. Will repost after I install the new motor.

Ok yes, that makes sense.

Here's the motor for your model:
DC31-00055G Motor

Installed new motor last night and my dryer runs like a charm. It now hums instead of sounding like someone on old roller skates with the metal wheels. What I found was the heater switch circuit mounted on the motor was burnt inside on one side of the switch contact points.. Because I could not locate that part, I had to replace the entire motor. Thanks for all the informative posts on this blog. I found them enormously helpful as well as youtube.
