I just got a BIG combo oven and microwave from my daughter. She said she
had not used the microwave for a year and a half, and my son in law isn't
mechanically inclined, so they got a new one. Oven, MW combo and all.

I pulled the panels and looked for the obvious. The fuse was quite
corroded. I pulled it, polished the ends. It's a small Buss type fuse.
Cleaned the contacts, too. Reassembled.

Had to trim the door hooks a slight tad, too to get it to release when you
push the release bar, but works like a charm now.

I have to put a plug on it tomorrow, and test, don't know if that solved the
problem. Could the corroded fuse on the end have caused it to stop
conducting electricity? I did a continuity check on it using a 9v. battery
and tester, and the reading was right at 9v., so I think the fuse is good.

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.

Fire it up, and hope you don't _really_ 'fire' it up. That's what I'd do.



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.
