Function and Importance:

The accumulator/filter drier acts as a critical filter by removing moisture and contaminants from the air conditioning system. These contaminants cannot be removed by flushing alone, making replacement of the accumulator essential during any system service. Replacement is required to validate compressor warranty and must be performed anytime the A/C system is opened or serviced. A leaking or open system can cause the desiccant bag to become saturated within hours, rendering the unit ineffective.
