Goodman B1756020L Vertical Drain Pan — 23 x 20 inch OD

The B1756020L is a genuine OEM Goodman 23 x 20 inch (outside dimension) vertical condensate drain pan for the WAHMV4260P4ACA air handler and compatible Goodman/Amana units installed in the upflow/downflow (vertical) position. The drain pan collects condensate from the evaporator coil and channels it to the drain line. A cracked or corroded pan causes water leaks and property damage — this OEM replacement restores proper drainage.

Specifications

Dimensions: 23" x 20" outside dimension
Orientation: Vertical (upflow/downflow) installation
Function: Primary condensate collection
OEM Part Number: B1756020L
Fits Model: WAHMV4260P4ACA
Brand: Goodman / Amana

OEM vs. Generic

Drain pans are model-specific — this OEM pan matches the exact footprint, coil seat, and drain-port location of your air handler so condensate drains cleanly with no pooling. Generic pans risk poor fit, standing water, and overflow. OEM is the reliable choice for leak-free operation.

Installation Difficulty

Moderate — requires removing the coil to swap the pan and re-sealing the drain connections. Disconnect power and confirm the drain line is clear before reinstalling.
