Looking through the old post, our switch was 150 degrees which was way to high to ever allow the fan to come on. I know on the newer 2 door models that was supposedly corrected. Reguardless it's controlled by a switch now.
As Jubal said it's clipped to the refrigerant line at the condenser toward the top of the fridge.
