OEM Goodman Horizontal Drain Pan for ARUF018 Air Handler — B1756021L

The Goodman B1756021L Horizontal Drain Pan is a genuine OEM condensate pan engineered for Goodman/Amana ARUF018-00A-1A 1.5-ton air handlers installed in the horizontal configuration. It collects condensate from the evaporator coil and channels it safely to the drain line, preventing overflow, water damage, and microbial buildup inside the cabinet. Using the exact factory pan ensures correct slope, drain-port alignment, and a leak-free seal against the coil assembly.

OEM vs. Generic

This is a genuine Goodman OEM pan, molded to the precise cabinet dimensions and drain geometry of the ARUF018. Generic or universal pans frequently misalign with the factory drain port, causing slow leaks and standing water. The OEM part guarantees a drop-in fit and preserves your equipment warranty.

Installation Difficulty

Moderate. Requires removing the coil access panel, disconnecting the existing drain line, and swapping the pan. Most experienced DIYers complete the job in 30–45 minutes; we recommend a licensed HVAC technician if the coil must be lifted. Always confirm your unit's orientation and model tag before ordering.
