The Goodman B1756028L Horizontal Drain Pan is a genuine OEM condensate pan engineered for horizontal (attic/crawlspace) installations of the WAHME3137P4ACA air handler. In horizontal mounts the pan must capture condensate across the full length of the coil, where any crack or warp can send water across a ceiling. This factory replacement restores a watertight, properly pitched drainage path to protect your home and equipment.

Type: Horizontal condensate drain pan

OEM vs. Generic

This genuine Goodman OEM pan matches the coil slab and primary/secondary drain port positions exactly. Generic horizontal pans often lack the correct slope or secondary drain location, which defeats the safety overflow connection. OEM guarantees code-compliant fit and dependable drainage.

Installation Difficulty

Moderate (3 of 5). Requires removing and reseating the coil, then re-plumbing the primary and secondary drains with proper pitch. Budget 60 minutes. Test for leaks by pouring water through the pan before closing the cabinet, and disconnect power first.
