 Sure sounds like a thermal limit switch. It could also
be a Poly-Fuse.
 As for voltage of the transformer, if it is bad, one can
still determine the ratio by cutting the wires off with
a single cut per turn and then count the wires for the
primary and secondary. One does have to watch out if there
are taps, other than center tap.
