My Ge Microwave Stopped Heating

This high voltage powers the magnetron to heat the food.

My ge microwave stopped heating.

The high voltage diode is located near the magnetron and the high voltage capacitor so access will require removal of the cabinet. When your microwave turns on but does not heat up it may mean the door switch is broken. If the diode burns out the magnetron won t receive enough voltage to operate preventing the microwave from heating. Ge microwave troubleshooting the table lists possible simple malfunctions of the microwave oven and methods for their correction available to virtually all users who do not have special knowledge in electronics.

The problem arises when this diode which doubles up the voltage to as much as 5 000 volts to facilitate microwave heating burns out. Ge microwave not heating. If the microwave runs but is not heating it could be one of many components. Check to ensure the door is closed firmly.

The diode converts the a c power output of the transformer to d c doubling the voltage to nearly 5 000 volts. The door switch can also be called an interlock switch. The technician should also not forget the door switch since some of them can cause the same issue. My first thought would be a blown magnetron.

Close it firmly but do not slam. Make sure the timer function was not inadvertently used. Easiest fix you can find. If the diode burns out the magnetron won t receive enough voltage to operate preventing the microwave from heating.

This component helps provide the high voltage that powers the magnetron. On microwaves these can generally go dead usually with a popping sound. The door switch signals other microwave components to supply power when closed and to stop heating when open. A new and better video update for the previous one where i explain how to fix your microwave that works but doesn t heat.

Inspect the diode and if the diode is burned out replace it. I think there might also be a fuse in your microwave but i do believe that if it was a blown fuse your mw would not start up.
