OEM Goodman Vertical Drain Pan 23 x 20 in for ARPF486016AA — B1756020L

The genuine Goodman B1756020L Vertical Drain Pan (23 x 20 in OD) is the factory condensate pan for the Goodman ARPF486016AA air handler installed in the vertical/upflow configuration. The pan collects condensate from the evaporator coil and routes it to the drain line. A cracked, rusted, or warped pan causes overflow, water damage, and clogged-line backups. The OEM pan restores proper drainage and fits the cabinet without modification.

OEM vs. Generic

The OEM pan matches the exact footprint, drain-port location, and coil rail spacing of this air handler, so it drops in and drains correctly. Generic pans often miss on dimensions or port placement, leading to standing water and leaks. For a part that protects the home from water damage, OEM fit is the reliable choice.

Installation Difficulty

Moderate (3/5). Power down the unit, pull the coil to access the pan, swap in the new pan, reconnect the drain line, and test drainage with water before closing up. Plan 45–60 minutes and basic tools. Disconnect power and shut off water before servicing.
