OEM Goodman B1756028L Horizontal Drain Pan

This genuine Goodman B1756028L horizontal drain pan is a direct-fit replacement engineered for the WAHMV3137P4AAA air handler. The condensate pan collects and channels moisture produced during the cooling cycle away from the coil and internal components, protecting your air handler from corrosion, water damage, and microbial growth. A cracked, warped, or clogged drain pan is one of the most common causes of ceiling stains and water leaks — replacing it with the correct OEM part restores proper drainage and protects the equipment around it.

Specifications

Part Number: B1756028L
Type: Horizontal condensate drain pan
Brand: Goodman (OEM)
Fits Model: WAHMV3137P4AAA air handler
Orientation: Horizontal installation
Material: Molded corrosion-resistant pan

OEM vs. Generic

Genuine OEM Goodman drain pans are molded to the exact contours of the coil and cabinet, so the drain outlet, slope, and mounting points line up perfectly. Generic or universal pans often require trimming or shimming and can leave standing water that promotes mold. For a leak-free seal and warranty-safe repair, the OEM B1756028L is the recommended choice.

Installation Difficulty

Moderate — Requires removing the coil access panel and sliding out the old pan. Plan 30–60 minutes. Always cut power at the disconnect before servicing the air handler.
