Receiver / Drier: Operation

WARNING: This page is about a different car, the 2004 Dodge Intrepid, 2004 Chrysler Intrepid, 2004 Chrysler Concorde, and 2004 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.

High-pressure liquid refrigerant from the condenser flows into the receiver/drier. A drying agent, called a desiccant, is used to remove any traces of moisture from the refrigerant system. The receiver/drier also performs a filtering action to prevent foreign material in the refrigerant from contaminating the expansion valve. In addition, during periods of high demand air conditioner operation, the receiver/drier acts as a reservoir to store surplus refrigerant.

The A/C refrigerant must be removed from the system before removing the receiver/drier using a refrigerant recovery machine. Replace the receiver/drier if an A/C system is left open for an extended period of time.

The receiver/drier cannot be repaired and, if faulty, must be replaced.
