OEM Goodman Horizontal Drain Pan for ARUF030-00A-1A Air Handler — B1756021L

The Goodman B1756021L Horizontal Drain Pan is a genuine OEM condensate pan engineered for the ARUF030-00A-1A air handler installed in a horizontal configuration, such as attic or crawlspace applications. It collects evaporator condensate and routes it to the drain outlet, which is especially critical in horizontal installs where even a small leak can damage finished ceilings below. Replacing a rusted or cracked pan with the correct OEM part eliminates a common source of water intrusion.

OEM vs. Generic

Generic horizontal pans seldom match the length, slope, and drain-port placement required for proper gravity drainage, which can cause standing water and overflow. This OEM pan mirrors Goodman's factory slope and port location so condensate flows correctly and the secondary drain aligns as designed. In a horizontal install, the genuine pan is the safest investment.

Installation Difficulty

Moderate (3/5). Involves accessing the horizontal coil, transferring drain connections, and confirming proper pan slope — roughly 45–90 minutes for a technician. De-energize the unit and clear any standing condensate before beginning.
