The Goodman B1756020L Vertical Drain Pan is a genuine OEM condensate pan engineered for ADPF18241BA cased coil and air handler assemblies.

OEM vs. Generic

This OEM Goodman pan matches the exact slope, drain-port location, and footprint of the original, ensuring proper drainage and a leak-free seal. Generic universal pans often require trimming or adapter fittings and can pool water if the slope is wrong — risking overflow and float-switch nuisance trips. For a guaranteed fit on ADPF18241BA equipment, the OEM pan is the safe choice.

Installation Difficulty

Moderate. Replacement involves powering down the system, removing the coil access panel, disconnecting the existing drain line, swapping the pan, and re-sealing connections. Most DIYers with basic tools can complete it in 30–60 minutes; otherwise a qualified HVAC technician is recommended.
