No, it looks like a light aluminum housing seated on a plastic plug with
two leads coming out. The aluminum case is open on top and there a metal
plate floating around inside the open top. If depressed it's kind of like
a
clicker, i.e. it's convex to the opening. Any idea?

Sounds like a device known as a "klicks-on" thermal limit switch. Similar
items are used in larger electric duct heaters in building HVAC systems. If
all else fails take it to a HVAC wholesaler and see if they can get you
something similar. Or a larger HVAC repair shop and see if they have an old
one lying around. They have different temperature ratings and either reset
automatically as they cool or have a button to reset them manually. The
little disk is bi-metal and bends as temperature increases, eventually
snapping across and opening a switch inside.

Ok, this one has a bi-metal thermostat. The contacts are corroded
from the salt air. Just replace it....

Is it just me or did the US and UK just capture 1/3
of the world's sweetest oil supply? What idiot wants to
GIVE IT BACK?!!
Let's do what Europeans have been doing for centuries.
DIVIDE UP THE SPOILS OF OUR CONQUEST! Gas will be
$US0.50/US gallon again, STUPIDS!

Rant over, good night.

It's good to blow off a little steam. Ask any of the guys who run the
boilers!

Yup, it's a bimetallic snap switch. Thanks for your help!

The electronics home-build hobby is in free-fall, and Radio-Shack is
accomodating it accordingly.

Jeffery,
From the part number it is some sort of temperature cuttoff fuse, maybe
tripping at 98C. For example the ones used in coffee makers usually trip
anywhere from 110C to 191C depending on the model and brand. It is a safety
device to protect from runaway heating. If yours tripped, you may well have
a dangerous problem which caused it to do its designed function and protect
you. That is also why they are not auto reset devices. Be very careful
about replacing it.

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!
