Goodman B1756020L Vertical Drain Pan (23" x 20" OD)

The B1756020L is a genuine OEM Goodman vertical condensate drain pan sized to fit the ADPF304216AC air handler / evaporator coil assembly. The drain pan collects condensate from the coil and channels it to the drain line. Cracked, warped, or algae-clogged pans cause water leaks, ceiling stains, and water damage — making this an important preventative replacement on aging systems.

Outside dimensions: 23 in x 20 in OD

OEM vs. Generic

The genuine Goodman pan matches the exact footprint, drain port location, and coil seating of the original, so it drops in and drains correctly. Generic pans rarely match the port position and can leave standing water or misalign the coil. For a leak-prone component, OEM fit is well worth it.

Installation Difficulty

Moderate. Requires removing the access panel and sliding/lifting the evaporator coil to access the pan, then reconnecting the drain line. Plan 45–90 minutes. Power down the system and have a towel ready for residual condensate.
