Here is the link to the manual. It is on page 16.

Remove vent grille, then remove control panel. Check wire to cavity thermostat. Sometime wire bundle and small space causes poor terminal connections on this thermostat and will burn wire terminal. Cut off bad part of the wire, install a small terminal end, reconnect to thermostat. If thermostat is destroyed, also replace thermostat.

It sounds like the magnetron overheated and opened the thermal fuse on the magnetron.

This can be caused when the internal cooling fan is not running or by a magnetron that is failing.

When I say internal cooling fan, I do not mean the hood vent exhaust fan which you can turn on and off manually.

I'm instead talking about the internal fan which comes on automatically whenever you microwave.

It is vital that the cooling fan runs, or the magnetron will be destroyed.

There should be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

The magnetron will have a 5 to 9 year warranty. Your manual will tell you that.

If needed, GE may send you a replacement magnetron. GE Customer Service is here.

I called Public Service and they suggested either a dedicated line or upping tha amps of that c-breaker. I need to call an electrician to help me decide which is best for my house.
