Ge above stove microwave not heating.
If any of the door switches fails the microwave will not start or heat.
The most likely reason why your microwave is not heating up is either the magnetron is damaged or the components that power the magnetron are damaged.
How to test a microwave high voltage diode with a multimeter.
We took it apart to find what was wrong and how to resolve it.
Pull the plug out of the wall power supply and wait a moment.

Close it firmly but do not slam.
Microwave runs but does not heat.
You will need to reset the time of day if you perform a hard reset.
Check to ensure the door is closed firmly.
Microwave runs but does not heat.
Link to fuse we use.
Unplug the microwave oven then plug it back in.
Plug the ge microwave back into the wall power supply to reset any anomalies with the microwave s memory.
This high voltage powers the magnetron to heat the food.
If any of the door switches does not have continuity replace it.
So if you are sitting there and wondering why is my microwave not heating up then the short guide here will help.
Open the door and close securely.
Perform a hard reset.
If the microwave runs but is not heating it could be one of many components.

This could be caused by a problem with the high voltage diode which helps to power the magnetron.
To determine if any of the door switches are defective use a multimeter to test each of the switches for continuity.
Locate and remove your high voltage diode to test it for continuity.
Plug not fully inserted into wall outlet.
Make sure the timer function was not inadvertently used.
Start button not pressed after entering cooking selection.
Mangetron assembly is the device that generates the microwave heat.
Our ge over the range microwave stopped working.
If the diode burns out the magnetron won t receive enough voltage to operate preventing the microwave from heating.
This confirms the engagement of the door s safety mechanisms.
Inspect the diode and if the diode is burned out replace it.
Your microwave may turn on but not heat up.
