Question about Jenn-Air JMC7000 Microwave Oven
It sounds like your cooling fan has failed, or possibly the relay on the control board. This same relay also runs the turntable. Is the TT working?
It's critical for the cooling fan to work, or the magnetron can overheat, which will cause the thermostat to interrupt power until it cools backs down. Sounds like what happened to you.
If it gets too hot or gets hot too often, it can be ruined.
A failed fan can cause such overheating and a buildup of moisture as well.
