thermal Fuse for breadmaker
 

My breadmaker has a dispenser function activated by a plunger tyoe
action, which uses a small electric motor. The motor seems to have a
small thermal fuse that has opened, probably when I was testing it.
The numbers written on it are 115C, 250V, 1A. Its about the size of a
small resistor used for PCB's.

I ordered a thermal fuse from Goodman's.net, but I'm wondering if
anyone has ever replaced one of these, and if there is any chance this
component may be other than a thermal fuse.

Any comments would be much appreciated.

Thanks, Guy

US or UK? Radio Shack used to sell them.

Sounds like a 115 degree C thermal fuse, with a max carrying capacity of 1
amp. There's not usually any issues with replacing them, but you should make
sure that the motor is running correctly and unrestricted. The current and
operating temperature of a partially impeded motor, can go up substantially
from the norm. If you don't want to risk wasting your new thermal fuse,
temporarily wire in a 'standard' T1A fuse, and just check that all is well
first.

I'm in the US. I'll look at the Shack.

This motor only operates for a few seconds, as it is only required to
dump a tray into the breadpan. So it is not likely to overheat in
actual operation. I will test the motor again to make sure its
working. By the way, its only the size of a film cannister, probably
1/2 that. Thanks for the replies. Guy

Guy-

I replaced one in a water distiller, and a couple in Hewlett Packard
crystal ovens.

I think there were two temperatures available from Radio Shack, and
three or more from NTE (NTE calls it a Thermal Cutoff). These were
about the size of a 1 Watt resistor, or a little smaller. One ordered
from HP was about the size of a 1/4 Watt resistor or a little larger.

As you might guess, it is not recommended to solder such a device into
the circuit. When I found that necessary, I heat-sinked each lead with
a pair of pliers close to the body. Normally you would crimp such a
temperature-sensitive device, and one of the replacements was provided
with crimp-sleeves.

Is there any fuses that are not thermal?

A 'normal' fuse blows when the current through it exceeds its rating. (It
protects the equipment from "too much current.")

A thermal fuse blows when its temperature exceeds its rating. (It protects
the equipment from "getting too hot.")

Fred,

I didn't see your reply till just now, and thanks for the comments.
Yes it does seem a little dicy adding this thing into the circuit,
expecially because its connected directly to the filament-thin winding
wire for the plunger. I got a replacement from Goodman's, and I'll be
trying it soon. The good thing is that this circuit is not really
critical to the operation of the machin, so if I goof up no big deal.
By the way the replacement I got from goodman's is the same
temperature rating, higher current rating and about twice the physical
size of the original.
