GE over the range microwave making grinding noise

replace the turntable synchronous motor
look to ebay search for
ge jvm1650

then add turntable motor or browse down youll find a new motor
the coils inside may be duff

dont use the microwave until you retrieve what dropped inside when you removed the port. The grinding is most likely a foreign object that is hitting the moving parts of the microwave and causing sparking. It can catch fire

Spacemaker t/t motors are very easy to change. Removed the screws from bottom of microwave. the bottom panel will found towards wall. Mtr is in very center of unit. Should have 2 wires going to it

sounds like you will be needing a new turntable motor and perhaps the coupling as well.

hello Frank. Sorry to tell you that the magnetron is going bad and making that terrible noise. Since the inside of a microwave, even unplugged has up to 2000 residual and deadly volts of electricity I recommend either calling a pro or replacing the unit.

Sounds like the turntable motor is going bad.

Sounds like a bad magnetron. One test is to set it to run for 30 seconds on the lowest power level. As the microwave power turns off and on, the growling should cycle too.
