The Goodman B1756028L is a genuine OEM horizontal condensate drain pan for the Goodman/Amana ARPF364216AA air handler mounted in the horizontal (attic/crawlspace) position. It captures coil condensate along the full length of the coil and routes it to the primary drain, guarding against ceiling leaks and water damage in side-lay installations.
Horizontal pans must match coil length and drain-side orientation precisely — the OEM B1756028L does. Generic pans often leave gaps that let condensate bypass the pan, the most common cause of attic water damage. Genuine OEM is strongly recommended for horizontal applications.
Moderate. Involves removing the coil or end panel, sliding out the old pan, fitting the new pan, and reconnecting primary (and secondary) drain lines with proper slope. Plan 1–2 hours. Confirm a P-trap and float switch are in place when finished.
