Is your air conditioning system faulting by turning on and off at random, leaving you sweating in the hot summer days? The pressure switch shuts off the A/C compressor if the refrigerant pressure is too low or too high to protect your A/C system components from damage. If the switch is faulty, the A/C compressor will shut off at random intervals, or not turn on at all, without cooling the interior cabin. If this is the case with your A/C system, replace your pressure switch to restore cool air.
