I found a MW oven in the street a few weeks ago and brought it home thinking it either works or I'll tear it open and salvage the magnets.
It seemed dead, but yesterday I opened it up and the fuse tested dead (250v, 15amp). I had a 125v 15 amp fuse and putting it in, the oven appears to work.
Two questions:
- Can I leave that fuse in there or should I get a 250v 15 amp instead?
- A MW oven troubleshoot NOTE: Fuses do not usually blow on their own. A fuse may blow because of problems with the interlock switches or with high voltage circuitry. It is also possible, though rare, that a power surge will cause a fuse to blow.
I have a MW oven I prefer, and figure to store this in my garage for that day when my current one dies (they always seem to eventually). What are the interlock switches and can I fix a bad one? Or is it possible I could fix a high voltage circuitry problem? TIA for some help.

PS This oven was FILTHY! I cleaned tons of crud off the inside, but more interestingly, the ventilation holes were 70+% clogged with grease. It's all clean now. Could that bad ventilation have anything to do with that fuse being blown?
