OEM Goodman Horizontal Drain Pan for WAHME3137P4AAA — B1756028L

Goodman B1756028L Horizontal Drain Pan

The Goodman B1756028L is a factory OEM horizontal condensate drain pan engineered as a direct-fit replacement for the WAHME3137P4AAA air handler. Positioned beneath the evaporator coil, the drain pan captures condensate produced during the cooling cycle and channels it to the drain line, protecting the cabinet, ductwork, and surrounding structure from water damage and mold growth. A cracked, warped, or rusted-through pan is one of the most common causes of ceiling stains and nuisance float-switch trips, and replacing it restores proper drainage immediately.

OEM vs. Generic

This is a genuine Goodman OEM pan, molded to the exact cabinet dimensions and drain-port locations of the original. Generic or universal pans frequently require cutting, drilling, or sealant to fit and can leave gaps that allow condensate to bypass the pan. Choosing OEM guarantees a leak-free seal, correct slope to the drain outlet, and full compatibility with the factory float switch and drain fittings.

Installation Difficulty

Moderate. Replacement requires powering down the unit, removing the access panel, sliding out the coil or pan assembly, and transferring the drain connection. Plan for 45–75 minutes. We recommend a qualified HVAC technician, and that the new pan be tested with water before sealing the cabinet.
