Incorrect pressure can damage the compressor, hoses, and other A/C system components.

Your car’s air Conditioner compressor pressure switch, is responsible for giving and cutting off power to the air compressor of the air conditioning system.When the pressure goes below 25 psi, the pressure switch cuts the power going to the compressor, making it shut off momentarily. This is important, in order to prevent the system from freezing up, due to extreme cold. Air conditioning pressure sensors, also known as AC switches, turn off a car's air conditioning system whenever the refrigerant pressure reaches a lower extreme. This not only signals the need for a recharge of refrigerant, but also saves the compressor from running without the proper lubrication. If the AC.

If the pressure is too low on the low side of the system, this switch will open the 24v electrical circuit going to either the contactor or the defrost board safety switch terminal. This switch may open if the unit is low on refrigerant or if there is a major clog in the liquid line part of the system such as the filter drier, metering device.
