The Goodman 0162L00025 Bi-Flow Filter Drier is a genuine OEM liquid-line drier designed for the DBC3004SAA packaged unit and compatible Goodman/Amana systems. The bi-flow design allows refrigerant to filter in both directions, making it ideal for heat pump and reversing applications. It removes moisture, acids, and particulate contaminants from the refrigerant circuit to protect the compressor and metering device.
The OEM 0162L00025 uses the correct desiccant volume, fitting size, and flow rating matched to your system's tonnage and refrigerant charge. Undersized or generic driers can restrict flow or fail to fully dry the system, leading to acid buildup and shortened compressor life. Whenever the sealed system is opened, replacing the drier with the genuine part is best practice.
Difficulty: Advanced. Replacement requires refrigerant recovery, brazing the drier into the liquid line, pulling a deep vacuum, and recharging to spec. This is a job for a licensed HVAC technician with EPA certification. Always replace the drier any time the system is opened for service. Confirm the model number before ordering.
