Tip & How-To about Microwave Ovens
When a microwave works normally but just doesn't heat, then this is a
faulty magnetron. A replacement can be purchased at repairclinic.com or
partselect.com which shows a picture of the magnetron, how to replace
it and option to purchase it as well.
If the microwave is not getting power, then first remove the outside shell, then check the glass bus fuse. Make sure the thin wire inside the glass fuse reaches all the way across the fuse and is not broken. If fuse looks good, but still no power, Use a voltmeter and check the power from the power supply to the main circuitry board and make sure it is getting the correct amount of power. There is usually a label on the microwave that tells the DC voltage output.
