Does it look like a little silver bullet with axial leads and one end
is plugged with a white ceramic something?

If so, it IS a thermal fuse, designed to open the current when the
device gets too hot, usually 350F or something like that. It's a
one-shot affair, usually melted because the fan bound up and didn't
blow the heat out of the box or you covered the air intake. Whatever
overheated it needs to be corrected, obviously.

Of all places, RADIO SHACK has these thermal fuses in those new parts
drawers in what's left of the parts department. A buck or two....buy
two and have a spare you can't ever find again.

It's not a thermistor, it's just a soft metal element inside the
bullet that melts and opens the circuit, forever.

Hi all,

Okay, granted this is a $59 heater and not worth its weight in bubble
gum, but the darn thing quit working and it was easy to take apart. So...

I have isolated the part that has failed, however, I can't identify it
(other than as the overheat protector). I think it's some kind of
thermistor; it doesn't look like a fuse. I'm no electronics whiz -- it
could be damn near anything.

However, if I could replace this part, I'm certain I'd have a working
heater again (at least for maybe another month).

The number stamped on the part is: A56 50N3510 8A98 C

Web searches yielded zilch. There is no information to be found anywhere
on the heater, unsurprisingly.

Any information anyone could provide would be infinitely appreciated.
TIA!
