I bought a refurb'ed Bunn A10-series in 2002. I've
replaced both thermal fuses. One at about year 4 and
the other around year 6. Radio Shack online. They
were... I don't know... a buck a piece?

Oops. Looking back at an old post on alt.coffee,
I find,

I don't recall now what the OEM spec was on the thermal
fuses, and I can't find it in the online manuals, but at
the time I replaced them, 141°C. was the closest Radio
Shack had. This machine never blew a thermal fuse for
the first three years we had it, and then three fuses the
following three years.
