This unit appears to work but in reality doesn’t. When you go to heat something it will act like it’s working. Everything turns on but it will not heat anything at all. Any Ideas on what the problem may be or what I need to replace?
If I were playing the odds, I would say your magnetron (AP2025937) has failed. Some checks with a multimeter would confirm this, or lead us to some other item that needs to be replaced or adjusted.
