It might be the Dio fuse..You have to take the cover off unit..It will be on the side..It looks different than a normal fuse...There pretty cheap..Replace it and your unit might heat up again.Make sure you unplug it..Don't mess with anything else.I have done this before...Mine started working again...Why they put it on the inside? So you want see it. Many have gone to the land fields because of the internal Dio fuse...Good luck
2004 model will probably have trouble getting the magnetron for it or the program board to repair it
Generally the cost to diagnose it and the parts problem would make a replacement unit with a warranty a better proposition

If it's the cooling fan inside the main body of the microwave, I would suspect an open thermistor / temperature sensor. If it's the vent fan (for the grille across the top) then I would suspect the hood thermostat is shorted. The oven should have a "mini-manual" (tech sheet) inside, usually in the control panel frame behind the door open button. It shows these parts and how to test them. 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 You can find helpful exploded view diagrams and order parts by entering your model number here: http://tinyurl.com/gv383

inside microwave oven may be wiring damage check wiring and contorl circuit,
SOURCE: No power from Whirlpool.
The problem was a defective switch. There are 3 switches on mine. 1 on the top door latch, and 2 on the bottom. one of the switches on the bottom connected the power and neutral together, unless it was activated at the same time as the other 2, causing the breaker to trip or the internal fuse to blow. When unhooking the wire going from this switch to the other switch, everything works great now. Though I still need to replace the switch.
And for Basic 1. Yes my microwave did have a fuse in it it's ceramic, I got a pack of them at Radio Shack 4 for 3$ 250V 20 Amp. There should be a wiring diagram inside the microwave, mine was inside a black bag, so it may be hard to see.
Mine was up top next to the fuse behind the Plastic Grill and then a small metal grill. Some are behind the control panel, to fix this remove the screw at the top and then slide the control panel up and it should unhinge.

I am currently experiencing the same problem. I called in Sylvia Brown because I thought that my room could have been haunted...come to find out IT WAS!! She said I did not have a short in my microwave, and that the reason it was turning on was because "the spirit" in my room wanted to kill me. My microwave plate produced a white, foamy, brownish color which she said was what would have killed me. You need to get your houses/apartments looked at if you are currently having the same issue. We thought everything was ok, and come to find out we really were being hunted down by spirits. Run away....FAST!!!!
p.s. this is the above writer's roommate....she's NOT lieing!!!!! be on the lookout for the white foamy brownish spot....it WILL get you, it got me. DUN DUN DUN
We replaced the board behind the control panel. $130.00. If you do this make sure you can put the wires back the right way. My husband finally got it and our micro is working like brand newThanks to all who tried to help.
