QUESTION: I got the thermostat out, how do i tell if its messed up?


Answer
Put the thermostat in a pot and boil some water to a temperature of approx 230 degrees and watch to see if the thermostat starts to open as the water gets hotter and it should be fully open at 230 degrees.

This IS the most accurate way to tell if it is working correctly.
