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:

1. Can I leave that fuse in there or should I get a 250v 15 amp instead?

2. A MW oven troubleshooting site says:

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.

I've seen quite a few microwaves that had blown fuses for no apparent
reason. There's a chance of an intermittent problem, but it is
probably fine. If it blows again, there is a definite problem that
needs to be repaired. A 125v fuse is fine as long as it's a 120v
microwave.
