The genuine Goodman B1756028L Horizontal Drain Pan is the factory condensate pan for WAHMS4860P4ABA air handlers installed in the horizontal (attic or crawlspace) position. When an air handler lies on its side, the standard vertical pan can't catch runoff correctly — this horizontal-specific pan sits beneath the coil in that orientation to collect condensate and route it safely to the drain, preventing water damage in attics and ceilings where leaks are costly and hard to spot.

OEM vs. Generic

This genuine Goodman OEM pan matches the coil slab and drain-port geometry for horizontal mounting exactly, ensuring proper slope and complete drainage. Aftermarket pans often pool water at the wrong end, defeating the float switch and risking overflow. For attic installs especially, OEM fit is worth it.

Installation Difficulty

Moderate (3/5). Involves removing the coil to replace the pan and resealing the drain line, often in a tight attic space. Recommended for an HVAC professional; plan 1–2 hours. De-energize the unit before service.
