The Goodman B1756017L is a genuine OEM vertical condensate drain pan designed for ARUF036 and ARUF042 air handlers and compatible models. Mounted beneath the evaporator coil, this pan collects condensate during cooling operation and channels it to the drain connection. Over years of service, original pans can crack, warp, or clog with biological growth, leading to overflow, water damage, and float-switch shutdowns. Installing the factory pan restores proper drainage and protects the equipment and surrounding structure.
The genuine Goodman B1756017L is molded to the exact coil footprint, with drain ports and mounting tabs that line up the first time. Generic pans frequently sit unevenly, allowing standing water and microbial growth, and may not seal to the cabinet — risking leaks. The OEM pan ensures a flat, fully-draining fit.
Moderate (3/5). Requires pulling the evaporator coil to access and swap the pan, then re-sealing and re-checking drain slope. Plan for 45–90 minutes. Cut power and recover/seal refrigerant lines per local code before servicing the coil.
