I have struggled with mine for at least two years and finally got it fixed last night. Usually pounding on the front of the oven would get the power to come on and finally I pinned it down to tapping on the control section. Once opened up and plugged in I found a couple wires on one of the plugs when moved were causing the cut out. I then removed the circuit board and found cracked solder joints on the large pins of one of the connectors. I re-solder all the pins on that connector and the oven is fully repaired. Mid 1990 soldering robots didn't use enough heat on larger pins. This causes a fatigue crack after years of service and intermittent loose connection problems. Easy fix if you can solder and know where the cracks are.
