Check the main internal fuse. Unplug it, unscrew and take off the
cover, the fuse should be easily found in the back by the power cord.
It looks like a regular fuse but is white instead of clear glass
because microwave fuses are special. You'll have to measure it with a
meter as a result and be sure to replace it with the same kind. (try
finding them at radio shack) Hopefully there isn't something more
Hope ya fix it!

I would suspect the fuse or magnetron thermostat.

Is there power at the outlet? You say you checked the fuse ... is that the one inside the machine? Is the outlet protected by a GFI (reset for a GFI is on the GFI)? A GFI looks like a ordinary outlet but is very sensitive to electrical irregularities. Your circuit breaker may be on or your power panel fuse may be fine and the fuse inside your oven may be fine. If the GFI is popped, you have no power.
Try some other electrical device in the outlet. Does it work? Try an extension cord from a known hot outlet?
Beyond these tips, you may need professional help with this.
Hello if you have no power at the outlet, you may have saved your microwave. If the outlet is dead go to your house electrical panel and reset the breaker or replace the fuse. if the outlet is live and the microwave still won't power on you will have to choose between repair and replacement. Definitely get an estimate before agreeing to a repair as microwaves are very inexpensive today compared to even a couple of years ago.
Is the outlet ok? Can you plug somethng else into the outlet to see if the fuse or breaker controlling the outlet is ok? If there is power at the outlet, unplug the unit and remove the outside cover.
Look for a blown fuse on the motherboard. Replace it with the EXACT value of the original fuse. You can purchase a new fuse at Radio Shack or hardware store or auto parts store. Try powering up the unit again and see if it works now or whether the fuse blows again. If it blows again, the power supply may have been damaged. Was this a power outage or surge? Was anything else in your home affected?
