My GE (2.5 yr old) Microwave (JT3800SH7SS) will only run for a period of 10 - 30 seconds before power is briefly interrupted. The control board reports that power was momentarily lost. This can be repeated without waiting. Just open/close the Microwave door and start again. No other error codes. There are 2 AC interlocks: primary door and the monitor interlock (ensures magnetron not powered if door is open) I suspect that one of these interlocks is intermittent but my main question is the Magnetron thermostat, are these thermostats resettable? I am guessing not for safety reasons. The fact that the power failure is very brief makes me believe this thermostat is fine.
Looking forward to some advice.
Thanks
Jim

Hi Jim, Rick is very good at Microwaves, but he's been out sick since Jan. 2022

I know little to nothing about fixing them, but hopefully another tech can assist you.
