Just wondering. Don't know what got in there to cause the terminals
and fuse ends to corrode. Hope it works tomorrow when I fire it up.

It could have corroded and made things not work, it could have corroded
because the oven wasn't in service. It's hard to tell.

Just a quick thought about Microwave corrosion issues...

In my experience, if you insist that all foods/liquids be removed from
the oven immediately upon timer expiration, and always leave the door
open until the cavity is dry seems to greatly extend the lifespan of
these ovens.

If the cavity is especially wet, wipe it out and run the oven 3 or 4
minutes at power level 'zero'[1]... to run the fan/s sans magnetron.
....
[1] I've been told, (but don't know for sure) that running the fan/s
alone without the magnetron isn't possible with all microwaves.

A couple of brands of microwave ovens turn on the light and fan
if you pull out lightly on the door -- ie opening an interlock
but not the door itself.
