The Goodman B1756028L is a genuine OEM horizontal condensate drain pan designed for the Goodman AEPF303616BA air handler and compatible Goodman/Amana fan-coil units installed in horizontal (attic/crawlspace) applications. It collects condensate from the coil and routes it to the primary and secondary drain ports, protecting against overflow, water staining, and the corrosion or cracking that eventually defeats the original pan.
The genuine OEM B1756028L is shaped to the exact horizontal cabinet contour and drain-port layout, ensuring complete capture and correct drainage slope. Generic or trimmed pans frequently misalign, leaving low spots where water sits and overflows the secondary. In a horizontal attic install, where leaks do the most damage, the OEM pan is the dependable choice.
Moderate — horizontal access and re-leveling for proper drainage add complexity over a vertical swap. Pull the coil section, replace the pan, reconnect primary and secondary drains, and confirm slope. Expect 60–90 minutes; technician-level recommended.
