GE- Microwave- Started vapor/smoke and did not heat item! Is it repairable before we spend a fortune for a GE repair person to tell us NO For $100?
Answer Hello Bob,
You will need to open the unit to determine the cause of the failure. You can use the tech sheet inside the control panel to trace the circuits. Be sure to unplug the unit and discharge the high voltage capacitor before beginning to avoid personal injury.
everything works but will not heat ,could the compcsiter be bad and how to test
Answer Michael, When the capacitor or diode fail, there is usually a loud hum or growl noise from the microwave when the magnetron tries to heat. To test a capacitor, you have to remove power to the microwave, you'll need to discharge the capacitor by placing an insulated screwdriver or pair of pliers across the capacitor terminals, and mark and remove the wires from the capacitor. Using a multimete,on the lowest resistance setting, place the meter probes on the terminals. If the capacitor is "good" the needle or digits will increase in resistance, momentarily, and then reduce back down towards an "open" circuit. Good Luck and Thanks
