The Goodman B1756028L is a genuine OEM horizontal condensate drain pan built for the Goodman AEPF426016CA air handler installed in horizontal (attic or crawlspace) applications. It collects condensate along the full length of the coil and directs it to the drain connection, protecting the equipment and surrounding structure from costly water damage. Horizontal pans see heavy condensate flow, so a properly fitted OEM pan is essential for reliable drainage.
The genuine Goodman horizontal pan is shaped to the coil footprint with the correct slope and drain-port placement to ensure complete drainage. Aftermarket substitutes risk ponding water and overflow if the slope or fit is off. For horizontal installs, OEM is strongly recommended.
Moderate — Involves removing the coil or accessing the horizontal pan position and re-routing the condensate line. Suited to experienced DIYers and HVAC pros. Verify left/right orientation before installing and re-test drainage after the swap.
