Question about GE Spacemaker JVM1640SJ Microwave Oven
Microwave was not heating the food and we tried several times and now it does not even turn on.
SOURCE: wont heat food
It could be that the "grinding" noise was actually "arcing" taking place inside the cavity or uder the cover. The magnatron is possibly damaged or the h.v. diode. Should be repaired by qualified repairman

Remove the case and see if you can localize the smell. Likely suspects are a shorted high voltage diode (replace) or a shorted stirrer bearing (replace stirrer)--a fan-like device located within the sheet metal waveguide near where the microwaves enter the cooking cavity. Make sure to have a cup of cold water in the cooking cavity when looking for problems. The problem could also be the high voltage transformer or the high voltage capacitor, but these are more rare problems. There are no radiation problems with the case off, but there are high voltages associated with the magnetron and it's power supply.
