I put the dryer back together, planning to go at it tomorrow. It works fine now. I don't know, maybe there were some loose terminals, dusty terminals, cold solder, etc. Anyway, it works OK now. This puppy has been doing strange things intermittently since we bought it.
Diagnostics check OK. If it acts up again I'm just gonna test or probably replace the thermistor first. Hopefully its not the Main control board.
The manual has the detail I need for sure. Thx!
