OEM Goodman Horizontal Drain Pan for ARPF364216BA Air Handler — B1756028L

The Goodman B1756028L Horizontal Drain Pan is a genuine OEM condensate pan designed for horizontal-mount ARPF364216BA air handler installations. In horizontal applications the pan runs the length of the coil to catch condensate that would otherwise drip into the duct or onto the structure below. A failed horizontal pan is especially damaging because the unit often sits in an attic or crawlspace — the OEM replacement restores reliable, leak-free drainage.

OEM vs. Generic

This OEM Goodman horizontal pan is molded to the precise length, depth, and drain-port placement of the original. Generic substitutes seldom match the coil rail spacing or drain location, which causes overflow into the duct. The factory pan installs with correct pitch and no field modification.

Installation Difficulty

Moderate (3/5). Involves removing the coil to seat the pan, reconnecting both primary and secondary drains, and confirming proper slope and an unobstructed drain path. Allow 60–90 minutes. De-energize the system and follow refrigerant-handling code before opening the coil compartment.
