Receiver Dryer: Description and Operation
Receiver/Drier
NOTE: Installation of a new receiver/drier cartridge is not required when repairing the A/C system except when there is physical evidence of system
contamination from a failed A/C compressor or damage to the receiver/drier cartridge. Damage to the receiver/drier cartridge includes physical damage
to the receiver/drier cartridge shell or desiccant, or moisture contamination. Moisture contamination results only from a complete loss of refrigerant and
equalization of the refrigerant system pressure with atmospheric pressure for a period longer than one hour. If even a slight amount of positive refrigerant
pressure is present in the system before repairs are carried out, the receiver/drier cartridge should not be replaced.
The receiver/drier is integral to the A/C condenser/power steering combo cooler. It stores high-pressure liquid after it leaves the condenser core. A
receiver/drier desiccant cartridge mounted inside the receiver/drier removes any moisture from the refrigerant. The receiver/drier desiccant cartridge is a
separate component and can be removed and installed separately from the A/C condenser/power steering combo cooler.
