Customer Questions and Answers for Control Panel Assembly by Ge

Hello Nick, thank you for contacting Appliance Parts Pros. From the manufacturer's wiring diagram, it does not appear that the microwave and oven share any common connections except where the entire unit connects to the home's wiring, this indicates either a poor connection or source power electrical issues. I recommend turning the unit off at the breaker and checking those connections are secure and undamaged at the unit.
