After unwrapping a few layers of paper,plastic & wax/lacquer, I found a
little square black device about .200 x .250 x .050 thick. I don't have
a strong enough magnifying glass to read it, but in is in series with
one of the input lines, and it is open. I'm guessing some type of
thermal limiting fuse. Bypassin it shows the primary winding to be good.
As a matter of fact, a few days ago I took apart a cheap 3 speed fan,
which had a similar device stuck to the windings, and it was also open.
Anyhow, until I get a stronger magnifying glass, what is it?

Thermal fuse or thermal overload?

Surprised no one answered. It is a thermal device. Can't tell you if
its supposed to auto reset or not. I had a similar situation on a
furnace blower motor. I could never find a replacement part.
Obviously, someone makes them & sells them. You could bypass the
device, but then you are opening yourself to the fire risk. You might
try companies like Parts Express, Digikey, or call Klipsch tech
service. Many times, these guys will help.

I've found the exact manufacturer. It's made by Thermtrol. The exact
picture showed up when I searched for it on their home page. It's a one
shot device, set to open at 127 degrees C. I requested one as a free
sample. Hopefully I'll get it.
