Still trying to figure this thing out. I replaced the main pcb and still no compressor but the fan runs. I can jump the 2 terminals on the bigger relay on the main ocb and the compressor will run. After I replaced the main PCB I replaced sensor assembly and get the same results. Could a bad sensor assembly burn out a new main PCB or is there something else I am missing.
ANSWER Hi Mark. NO the sensor only supplies the main board with its temperature readings. It seems like you need to ohm out the main control switch and see if it is not open. Cover assy. part # 3551A20122A. Thank You.
