About A/C Trinary Switch

The AC trinary switch is a component that plays the role of a safety switch for an air-conditioning system. It has the task of shutting off the power to the air-conditioning clutch if the refrigerant pressure is excessive or on a decline.

AC trinary switch function

The AC trinary switch is a vital part of the AC system because it turns off the power to the AC clutch when the refrigerant pressure is too much. It also has the task of turning on the engine cooling fan when the compressor is working. This type of safety switch should always be included because it helps bring down the internal temperature and it ensures that the system does not get damaged.

Common issues with a faulty AC trinary switch

A faulty AC trinary switch can cause the compressor to not come on, the car won't cool properly, and an erratic AC system.
