Your assessment is correct, more or less. It protects from
overload. I found a similar item<br>
in a motor on an attic exhaust fan. I called around and found a
fellow that knew exactly what<br>
it is. He said it's just a cheap (solid-state) fuse that makes
money for repair techs and manufacturers.<br>
<br>
All I needed to do was to replace it with a reasonable amp rated
fuse in a replaceable fuse<br>
holder. Fuse holder cost me $5; already had a fuse. New motor
would have cost me $60.<br>
<br>
IMO, you can safely replace the device on the transformer with an
appropriate fuse.<br>
That's not from expertise so much as it is from experience. Any
fuse will blow if its<br>
temperature is too high. The transformer is fixable! :)<br>

should be a picture of the innards of a 120VAC to 24VAC wall wart.
<br>
<br>
Which is somewhat obscure, and is now farschtunken. (zero
output)<br>
<br>
The big clue is infinite resistance across the 120V side. <br>
<br>
Tearing it apart, I'm seeing about 80 ohms across the primacy
coil, and this little black thing, which shows infinite resistance
both ways. <br>
<br>
I may just end up getting a replacement adapter, cutting off the
cable, and splicing on the obscure connector, but I'm curious what
this thing is. <br>
<br>
Writing on it says: <br>
<br>
<blockquote> AUPO (rombus shape with some letters inside)<br>
A 2-1 A-F jet<br>
115<degrees-symbol>C R1<br>
<br>
</blockquote>
If I had to guess, then I'd guess it's some kind of thermal
protection device that is normally conducting straight through,
but opens up at 115 degrees to protect from overload? <br>
<br>
Any thoughts on what this is, and if one could obtain a
replacement part somewhere? <br>
<br>
