Looking trough the posts I didn’t see one that mentioned a smell as well.
Microwave seems to work but does not heat, makes a loud humm and after a few seconds you smell an electrical smell like insulation buring or a overheated transformer. I figure the Magnatron is not working but what would cause the smell. I am tring to decide whether to junk it after eight years or try to make repairs.
Thanks,

You could have a bad capacitor or diode. If the cap is open or the diode is closed or both, then this could be the problem. You should get a reading on the cap but not on the diode. If the diode fails then you will get a reading. The capacitor stores the energy being produced by the transformer while the diode makes and breaks that connection about a billion times per second. This causes the magnetron to agitate the molecules on whatever food or bev you have in the oven. The constant agitation produces friction, friction produces heat.
Lost me! You say get a reading???
Plus the back is on with some special screw. Looks like a star screw hole with a center pin to keep out anything but a special bit.

If this my problem what is the approximate cost to repair
Sounds like what is wrong with my Amanda microwave. What is approximate cost to repair? Is it cheaper to replace?
