The Goodman B1756020L Vertical Drain Pan is a genuine OEM condensate pan sized 23 x 20 inches OD for the WAHMS4961P4AAA air handler installed in the vertical (upflow/downflow) orientation. The pan collects condensate that forms on the evaporator coil and channels it to the drain line. A cracked, rusted, or algae-clogged pan leads to water overflow, ceiling/floor damage, and float-switch shutdowns — a fresh pan protects the equipment and the surrounding structure.

Specifications

OEM Part Number: B1756020L
Component: Vertical condensate drain pan
Dimensions: 23 in x 20 in (outside diameter)
Orientation: Vertical
Fits Model: WAHMS4961P4AAA

OEM vs. Generic

This genuine OEM pan is molded to the exact coil footprint and drain-port location, so it seats flat and drains completely with no pooling. Generic pans rarely match the port placement and can sit unevenly, trapping standing water and breeding biofilm. For reliable condensate management, the OEM pan is the correct fit.

Installation

Difficulty: Moderate (3/5). Requires sliding out the coil/pan assembly, transferring the drain fitting, and confirming proper slope to the drain. Plan 30–60 minutes. Power off the unit and clear the drain line before installing.
