Gentlemen,

I refer to you this photo of the internals of a typical modern cheap and
nasty blanket controller. All the components it uses are shown on this
board: just 5 diodes, 3 resistors and some 'mystery component' whose
function is presumably to sense overheating from the two resistors it's
between and cut-back the mains voltage to the blanket itself if needed.

Question is, what is the correct name for this 'mystery component' and
what should it read resistance-wise when cold?

Thanks!
