I've boiled water and checked them that way before, but is that the only way to see if a t-stat is working? Is it right that a 195 t-stat is "full-open" at 195 degrees?
Seems to me that if this is the case that I should see a fully open thermostat in boiling water. But the one I am questioning is not fully open in boiling water, to my knowledge.
Thanks, Snowman
