OEM Goodman Vertical Drain Pan 23x20 in OD for ADPF304216AB — B1756020L

The Goodman B1756020L Vertical Drain Pan is the OEM condensate pan for ADPF304216AB evaporator coil and air handler assemblies. Measuring 23 x 20 inches OD, it captures and channels condensate away from the coil to prevent water damage, mold, and overflow. Cracked or rusted pans are a leading cause of ceiling and cabinet water leaks — a direct OEM replacement is the reliable fix.

OEM vs. Generic

The OEM B1756020L matches the exact drain port location, slope, and footprint of the ADPF304216AB cabinet. Generic or trimmed universal pans risk improper drainage slope and standing water. The factory pan guarantees correct primary/secondary drain alignment and corrosion-resistant material.

Installation Difficulty

Moderate. Expect 45–90 minutes. The coil typically must be slid out to remove the old pan; reseal drain connections and verify proper slope toward the drain port before reassembly. Test with a cup of water before returning the system to service.
