I have done some testing at the main PCB board and so far I have disconnected the main power wires from the large relay. These are the large blue and black wires. With my test meter connected on to the relay terminals I got no voltage when the unit is plugged in to the wall . The blower runs OK. Prior to this work I rechecked all the items at the thermister, the thermal fuse, the thermostats on the coil enclosure, and the coil itself. All items checked correct with continuity or a proper resistance reading. This PCB is encapsulated in a clear plastic coating and I dont think it can be opened up for testing w/o destroying something. Any other suggestions ? I defintely have 220 volts out of the wall outlet as I ran another electric dryer using this supply with no problem.
