If it blows the fuse as soon as you press the start button, you have a shortened high voltage capacitor

There are parts inside the unit that fail and can cause this. One such part is the high voltage diode. You can repair it yourself but if you dont know electronics, I dont recommend it.

The most common suspects are the high voltage transformer and the magnetron. It's also possible you have a flaky door switch or loose door switch mount. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your model number here: http://tinyurl.com/gv383
SOURCE: Microwave quit working
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
It may also be the high-voltage rectifier diode.

Usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven. When it blows, you need to have a qualified appliance repair technician replace it.
Door switch
If the fuse isn't the problem, check the door hooks and the door-release button. When these are broken, the door switch doesn't activate, so the oven can't work.
SOURCE: microwave trips circuit breaker when plugged in
The circuit is probably a 20Amp circuit (see the number stamped on the circuit breaker switch). Most likely, it is the same circuit as the refrigerator, crock pot, window A/C unit, etc....
Also, if you are using an extension cord or a power strip or a surge protector. Those may not have a high enough power rating.
One other possibility (not likely) is that the circuit breaker is a 15Amp and the microwave is 1500 watts.
What else is cut off when the circuit breaker is tripped?
Solution is to use a different outlet for the microwave, or turn off any other applicance in the same circuit (except the refrigerator, of course).
Hope this helps!
