Question about GE Spacemaker JVM1640SJ Microwave Oven
Our GE spacemaker microwave, model number JVM1653BH01, mfrd 11/2003, (1.58 kw, 2450 MHx output). suddenly stopped heating. The light still comes on, and the turntable rotates, but no heat. A neighbor said it was one of the fans, but we think it might be a fuse. Any suggestions?
I have a GE Over the oven microwave Model JVM1660BB. When heating it had started making a low humming noise. I could open the door and then close it, and the noise stopped. Now the oven won't heat at all. the light comes and the fan works. Jimbo

If it is working but not heating, then test the high voltage
capacitor,the rectifier diode.or the magnetron. If all this are fine,
test the control board.
The diodeand capacitors can be tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, evenif power is off.Capacitors can get discharged by shorting their two contacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.
