OEM Goodman Horizontal Drain Pan for ARUF049 Air Handler — B1756028L

The Goodman B1756028L Horizontal Drain Pan is the genuine OEM condensate pan for ARUF049-00A-1B air handlers configured for horizontal (attic or crawlspace) installation. In a horizontal coil orientation the pan does more work — it must catch and route condensate against gravity's tendency to pool — so a precise factory-matched pan is critical to prevent overflow, ceiling stains, and coil corrosion.

OEM vs. Generic

Horizontal pans are application-specific: the drain port, slope, and coil cradle must align with the cabinet exactly. The OEM B1756028L drops into the factory rails with no modification, while generic pans frequently leave low spots that hold water and grow biofilm. For attic installs where a leak means drywall damage below, OEM is the safe choice.

Installation

Difficulty: Moderate to Advanced. Horizontal access is often tight (attics, closets). Power down the unit, pull the coil access panel, support and remove the coil if required, swap the pan, and re-route the condensate line and any secondary/float switch. Budget 45–60 minutes and verify the pan slopes toward the drain before reassembly. A secondary drain pan or wet switch is recommended for overhead installs.
