The Goodman B1756028L Horizontal Drain Pan is a genuine OEM condensate pan designed for ARPF36421BA air handlers installed in the horizontal (attic/crawlspace) position. In horizontal applications the pan runs the length of the coil to capture condensate across the full coil face, then routes it to the drain fitting — critical for preventing ceiling and attic water damage.

Specifications

OEM Part Number: B1756028L
Part Type: Horizontal condensate drain pan
Fits Model: ARPF36421BA (Air Handler)
Material: Corrosion-resistant molded plastic
Orientation: Horizontal (left or right) installations
Fit: Direct OEM replacement

OEM vs. Generic

The genuine Goodman OEM horizontal pan matches the coil length, drain-port side, and mounting geometry of the original — details a universal pan rarely replicates. Because horizontal installs are usually in finished or hard-to-reach spaces, a precise OEM fit is the difference between a dry attic and an expensive water claim.

Install Difficulty

Moderate to Advanced — horizontal pan swaps often require pulling the coil and working in a tight attic or crawlspace. Allow 60–90 minutes and pour-test the drain before sealing the unit. Professional installation is recommended for attic applications.
