The Goodman B1756028L is a horizontal condensate drain pan engineered as a direct-fit replacement for the Goodman AEPF42601AA air handler when installed in the horizontal (attic or crawlspace) orientation. It collects condensate runoff from the evaporator coil and directs it to the drain connection, safeguarding the cabinet and the living space below from water intrusion. Installing a fresh OEM pan eliminates the cracks, corrosion, and warping that cause overflow and ceiling damage.
The genuine Goodman OEM pan is shaped to the AEPF42601AA's horizontal cabinet and drain-port geometry for a precise, leak-free fit. Generic pans frequently need modification and may sit unevenly, risking standing water and overflow. Given the water-damage stakes, the OEM B1756028L is the safe choice.
Moderate — Involves opening the air handler, sliding out the coil to free the existing pan, fitting the replacement, and reconnecting the drain line with correct slope. Recommended for an HVAC technician. Verify drainage and check for leaks after install. Always de-energize the unit before servicing.
