My whirpool microwave will not heat, is it a bad magnatron?
Answer Hi. The magnetron W10245183 should read less than 1 ohm. To test the capacitor, you will look for a spike on the meter, and then a drop to 0. You can test this with a multi-meter TJMA-DM1. Thank you.
The microwave no longer heats anything up. It turns on and runs just fine. It just does not heat anything. So, what could be the number one problem with it?
Answer Helllo Justin. If there is a loud humming noise coming from the unit, then you will need to check and see if the magnetron and diode are bad on the unit causing the issue.
