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!
