Before disassembly I troubleshot the dryer which would not run as follows:
- pressing "start" engaged relay and started control timer so start switch was fine;
- opening dryer door opened relay stopping timer and dryer light came on so door switch was fine.
So I dove in.
The installed motor was clearly brunt... as in really fried. The plastic fan on the front end of the motor had melted in half and one-half had melted/burned It was a Chinese "replacement motor" that lasted just under 2 years. Clearly the Chinese motor's overheating safeguard did not do its job. When I installed the Chinese motor 23 months ago the dryer did function, so I got lucky (or was "good") once. Not so much this time...
The unit's original lasted 18 years... thus my springing for an OEM at Parts Dr. this time. At roughly 2x the price and 9x the life, OEM was the clear choice.
I did check the thermistor on the exhaust duct and it showed continuity.
I'm going back in and will update if I find anything, but reviewing the install and reassembly in my mind's eye, I don't think I missed or miswired anything.
Is there a connection at the motor that needs to be satisfied and might not be???
FYI: My dryer has the "old broken belt switch design". I installed the protective tubing that came with the OEM motor.
Thanks in advance for any help offered...
