    Why does the fuse inside my GE microwave blow whenever I start cooking?
    About a year ago my microwave (I'll call it GE #1 in this thread) just stopped. Wouldn't turn on. No cooking, no keypad, no lamp; nothing. Nothing happened when I plugged it into the wall. And so that micro sat dysfunctional over my stove-top for several months, until I bought a new one.

    And wouldn't you know... two weeks after I bought and got the new one set up (I'll call it GE #2 in this thread) , it broke. And so that sat for many months, until now.

    So, I decided to pull GE #1 out of storage to really see what its problem was. Turns out, it was just a blown fuse. I bought replacement fuses, correct voltage and amperage (250V 15 amp), stuck one in, and plugged themicrowave in. The keypad turned on and I reset the clock. So far so good!

    But then I was pushin' it: I pressed "COOK TIME," set my time limit, and pressed START. Normal sounds start, fans begin to turn, and one second after I press START, the micro turns off. Everything. Keypad is off; nothing. THe fuse is hot, and it is blown.

    By the way, the reason I even mention GE #2 here is because I wanted to have a backup story for anyone who says that I should buy a new microwave (especially because they don't cost too much). Personally, I don't feel good about buying another dud. I'd rather fix my old, reliable one, the one with the best record: GE #1. That way, I'll only have one junker sitting around. And as for why we didn't return GE #2, I really don't know why. Kind of sad.

    So, after contemplation, I've decided on trying to fix GE #1 rather than GE #2. So, why is the fuse in GE #1 being blown? Is there a broken capacitor? Is the door switch faulty?Some component must be blowing the fuse.

    There is a 1 year warranty with #2 so get it fixed by someone that knows and for free.

    Magnatron, Capacitor, HV diodes in that order. Magnitron more likely if it slowly started no to heat as well.

    3000 VDC on that Magnatron.
