It may be the internal fuse, or the thermal fuse / thermostat / thermal cutout on the magnetron. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk

Magnatron is suspect. Need to put a voltmeter on the input (primary) side to the high-voltage transformer (big heavy iron thing in there) Should be getting 120Vac when it goes to cook cycle. Don't touch the other (high voltage) side of this transformer. If the power is there, you are looking at replacing the magnatron. Its affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"

SOURCE: ARE THERE INTERNAL FUSES IN
There's usually an input line fuse on a small circuit board (part of an input line filter circuit) in most microwave ovens. This is usually a 20 amp appliance fuse that you can purchase at most major hardware stores (you would need to look at the fuse to verify the rating). You would need to remove the exterior cover to access the fuse. Its usually located near where the power cord enters the unit. Make sure you unplug the unit prior to attempting any repairs to the interior circuits. Microwave ovens are particularly dangerous as the the voltage potentials in the high voltage network are in the 3000-4000 volt range. In addition, most manufacturers provide a schematic drawing with troubleshooting advice behind the operator console, or inside the interior cabinet wall. I hope this helps you.
