You guys are bloody awesome. Very useful information. My drier switch only has 2 wires and the condensor fan doesn't switch on when the ac is switched on. I also replaced the thermo sensor for a 75c-80c one and it still doesn't turn on at operating temp, which I'm not complaining about. Maybe it gets hotter when the temp is warmer, time will tell.

What is the reason for the condensor fan not turning on when the ac is switched on?
