Brian I tried to loosen the temp. switch and could not.I too cannot tell if it goes into a blind hole or if I loosen or break it my freon will escape.I also read that maybe I have a bad resistor or bad connections at resistor but have been unable to locate it.Would appreciate any more info on the matter.At this point I am thinking to just run some wires off the switch to a toggle switch and turn it off and on as needed.
