OEM Goodman 23 x 20 in Vertical Drain Pan for AEPF42601AA — B1756020L

Goodman B1756020L Vertical Drain Pan (23 x 20 in OD)

The Goodman B1756020L is a vertical condensate drain pan measuring 23 x 20 inches outside dimension, engineered as a direct-fit replacement for the Goodman AEPF42601AA air handler installed in the vertical (upflow/downflow) orientation. It captures condensate from the evaporator coil and channels it safely to the drain line, protecting the cabinet, ductwork, and surrounding structure from water damage. Replacing a cracked, warped, or rusted pan restores proper drainage and prevents costly leaks.

OEM vs. Generic

The genuine Goodman OEM pan is molded to the exact cabinet footprint and drain-port location of the AEPF42601AA, ensuring leak-free drainage and a flush fit. Universal pans often require trimming or adapters and may not seat correctly, inviting overflow. For water-management parts, OEM fit matters most.

Installation Difficulty

Moderate — Requires partial disassembly of the air handler to access and remove the coil/pan, then reseating the new pan and reconnecting the drain line. Best performed by an HVAC technician. Confirm proper slope and a clear condensate path after install. Always de-energize the unit before servicing.
