I have three thermostats, two of which do not work, and the third moves very little (< 0.5 inch). I am coming to the conclusion that it is the internal air expansion that makes the bellows expand and contract - can sombody confirm this? Somebody said there is an internal spring, but I do not think that is the case? If my assumption is right, than if I ID the holes in the bellows and repair them they should work again - right? Just wondering if they are originally filled with some form of inert gas or gas that has some special expansion properties? Anybody know for sure??
