I think that word is spelled "magnetron". You know, it has a magnet in it. That particular component is pretty tough, which, to me, says it is probably not broken.

I suspect Frigidaire is willing to sell you a part you don't need, and I'm not impressed by their generosity.

From the symptoms you describe, I am guessing there was some kind of failure, resulting in too much current draw. Too much current through, something, caused the burning smell. Then shortly after that, a fuse blew open, as a result of which nothing is powered now.

It would be neat if the burning thing was burned in like a really obvious way, that way you could find it just by looking for the charred, blackened, burned-looking thing.

I'm sorry if that seems vague. I think this page,

http://www.repairfaq.org/sam/micfaq.htm

is the place to go to for deeper answers, about what makes the microwave go, and a big list of possibilities for things wrong with it.

BTW, part of the high voltage supply for the magnetron has this one big capacitor which *could* conceivably still have a charge on it, for some amount of time even after the oven has been unplugged, and that is a part you want to avoid touching. I think the FAQ I linked to above probably has some details on that.

You should take the cover off and take some pictures of the circuit board (next to the door) and the filter where the cable goes in.

If in doubt also one pic of the big silver capacitor next to the transformer.

Without pics it is hard to give proper advise.

So far I would suspect that the main fuse is blown, possible causes are plentyful.

If a small electrolytic capacitor on the circuit board is faulty you should see that it is bulged out and also possible residue of the electrolyte on the circuit board.

If such a capacitor is the cause for the main fuse to blow I would suspect the repair to be hard unless you change the whole circuit board.

The Magnetron is not likely to fail as it does not have any pars to fail in it, the transformer can blow, which would be clearly visible on it's outside.

So please add some pics so we find the source of your problem.

Usually when there is a pop and that smell it means that a capacitor has exploded. They sometimes do that. It used to be a common problem in computer power supplies. Anyway, they can be replaced and they are pretty inexpensive but the problem is you have to know what you are doing to replace them. It requires taking the unit apart and removing the circuit board , identifying the component that blew and finding a correct replacement. Then it has to be soldered onto the board. If you know someone who can do that kind of work then go for it. If not then you might be stuck getting a new one.

I have noticed that there are circuit fuses your going to be replacing also.

I had something similar happen with one of mine. Moisture from the stove caused an IC to fail. Hopefully it's a fuse as Iceng said !

I'm kind of surprised that they recommended fixing it your self over offering you a discount on a new one.

Unless you would consider yourself well versed in electronics / Line voltage safety I wouldn't even touch it !

If you REALLY want to go for it, how about a Picture of the inside?
