The Goodman B1756021L is a genuine OEM horizontal-configuration condensate drain pan engineered for ARUF018-00A-1 air handlers and compatible Goodman/Amana indoor coils installed on their side. In horizontal applications the pan must run the full length of the coil to catch condensate across its lower face, so the correct horizontal pan is essential. A damaged or mismatched pan leads to leaks, overflow, and water damage in attic or crawlspace installs.

Specifications

Orientation: Horizontal (left/right) configuration
Function: Full-length evaporator condensate capture and drainage
Fits: Goodman ARUF018-00A-1 air handler
Construction: Molded OEM-spec drain pan
OEM Part Number: B1756021L

OEM vs. Generic

The OEM B1756021L is shaped to the exact length, depth, and drain-port position required for horizontal coil mounting. Generic pans may save money but seldom match the horizontal drain geometry, risking overflow — for horizontal drain pans we strongly recommend OEM for a guaranteed, leak-free fit.

Installation Difficulty: Moderate

Horizontal pan replacement typically involves sliding out the coil and takes 30–60 minutes. Disconnect power and clear the condensate line first. Verify the pan pitches toward the drain port, reseal the cabinet, and test drainage before returning the unit to service. Professional installation is recommended when coil removal is required.
