First thing, microwave oven is very danger apliance to repair due high voltage. Note that both of the relays on the control board switch the "neutral" side of the line, but that's no guarantee that they don't have 120V on them due to some other failure, since the neutral is floating. There is absolutely no doubt about the fact that a microwave is one of the most important appliances one has in his kitchen. If find blown fuse, check appliance for short circuits. I fix microwaves for a living, they store over 4 thousand volts in the high voltage section, and if you don't know what you are doing, don't take the cover off.Yours could be one of several problems, if it programs and goes through all the motions but no heat,then you have some type of high voltage problem, that could be a bad high voltage transformer,capacitor,magnetron on rectifier.take it too a pro or have a pro come to your house.good luck, + like rj713 said "in complete agreement", 06/21/2011 by john a, the high-voltage capacitor in most microwave ovens is bridged with a high-value bleeder resistor for safety.
