OEM Goodman Horizontal Drain Pan for ARPF374316BA — B1756028L

The Goodman B1756028L Horizontal Drain Pan is the OEM condensate pan designed for horizontally-installed ARPF374316BA air handlers and compatible Goodman/Amana systems. In a horizontal configuration the pan does double duty — it must catch condensate across the full length of the coil and route it to drain even though gravity is working against it — so dimensional accuracy is critical. This factory part is molded to spec for exactly that job.

Use it to replace a pan that has cracked, warped, or rusted through, eliminating ceiling stains, mold, and float-switch shutdowns caused by overflow.

OEM vs. Generic

Horizontal pans are far less forgiving than vertical ones — even a small fit error lets water bypass the drain. This genuine OEM pan matches the coil rails and drain boss precisely, so it seals and slopes correctly out of the box. Universal pans rarely match horizontal coil geometry and commonly leak.

Installation Difficulty

Moderate. Power down, disconnect the condensate line, slide the coil, and seat the new pan ensuring proper slope toward the drain. Plan 45–60 minutes; verify drainage with a water test before closing up.
