The Goodman 0121R00006PDG is a genuine OEM 29-inch base pan for the GSC130484BA 4-ton 13 SEER air conditioner condenser. The base pan is the structural foundation of the outdoor unit — it carries the compressor, supports the coil and cabinet, and channels condensate and rainwater out of the unit. Replacing a rusted-through or cracked base pan restores the cabinet's rigidity and prevents compressor and fan misalignment.
The OEM Goodman base pan is stamped to the exact 29" cabinet footprint with factory-located compressor mounts, fastener holes, and drain channels, so every component lands where it should. Generic base pans are rarely available for a specific Goodman chassis and typically won't align the compressor feet or cabinet posts. OEM is strongly recommended for a structurally sound rebuild.
Advanced — A full base-pan swap means removing the cabinet, fan deck, coil, and lifting/repositioning the compressor (which may require refrigerant recovery on the line set). This is a teardown-level repair best handled by a licensed HVAC technician.
