In the 1980s I had a Mr. Coffee type maker that the thermal fuse blew
(this was the first time I had seen one of these things) and I wanted
coffee. I cut the fuse out and connected the wires and it worked fine
for about a week. Then one morning I put the coffee on and went two
rooms away to pull in my email as I usually do. After a while I began
to smell something burning. I went back to the kitchen and there on
the counter top was the coffee maker with the tower melted down onto
the base and turning into a molten blob. I unplugged it and when the
mess cooled down I was able to scrape it off the counter top. I found
that the bimetal thermal cut-out had stuck closed and then I knew what
blew the fuse in the first place.

I learned my lesson and never eliminated a thermal fuse again. I'm
glad I had not left for work as I might have lost my house.
