OEM Goodman Horizontal Drain Pan for WAHMS4860P4ACA — B1756028L

The Goodman B1756028L Horizontal Drain Pan is a genuine OEM condensate pan engineered as a direct, factory-spec replacement for the WAHMS4860P4ACA wall-mount air handler. It captures condensate produced by the evaporator coil and channels it to the drain line, preventing water damage, corrosion, and overflow inside the cabinet. A cracked, warped, or rusted-through pan is one of the most common causes of ceiling and wall water stains under an air handler, so a clean OEM replacement restores proper drainage right away.

OEM vs. Generic

This is the genuine Goodman OEM pan, molded to the exact cabinet dimensions and drain-port locations of the WAHMS4860P4ACA. Universal or generic pans often require trimming, re-drilling drain ports, or shimming to seal, which risks leaks. The OEM part drops in and aligns with the factory gasket and drain fitting on the first try.

Installation Difficulty: Moderate

Replacement typically requires pulling the coil section, so plan for partial disassembly of the air handler. A competent DIYer with basic tools can complete it in about an hour; otherwise a qualified HVAC technician is recommended. Always disconnect power before servicing.
