GE Advantium Microwave turns on when door is closed
Model Number: SCB2000FBB Brand:
1 - 5 years
Builtin microwave turns on when the door is simply closed. It gives a low hum and no fans or other indicators. Controls work fine. Looked at the included schematic and saw that the only item in the microwave circuit that could cause the behavior is a single relay, designated as "Relay 2", that would be failed in a closed position. Found on a circuit board a relay labeled RY2 that ohm metered out as closed. The Technical Data sheet does not show the position or the circuit board that has that relay so I'm asking two questions. Since the only relay that has any markings with the number 2 is that one, is it a likely culprit and if it is what board do I need to order to replace it? It's on a largish CB at the top center of the oven, tucked in towards the rear of the oven. The multi-cables from the front panel controls and display are plugged into it. I can see no designation on the Tech data sheet or on the board that is visible without a full removal.
Thanks in advance for any advice.
