OEM Goodman 23x20 Vertical Drain Pan for ADPF48601BA — B1756020L

The Goodman B1756020L is a genuine OEM vertical condensate drain pan measuring 23 x 20 inches OD, designed as an exact-fit replacement for the ADPF48601BA air handler and compatible Goodman/Amana coils. The drain pan collects condensate that forms on the evaporator coil and channels it to the drain line. A cracked, corroded, or warped pan leads to water leaks, overflow, and potential water damage around the unit — making timely replacement important.

OEM vs. Generic

The genuine OEM pan matches the coil footprint, slope, and drain-port location exactly, ensuring condensate flows to the outlet instead of pooling. Generic pans often differ in dimensions or drain placement, causing standing water and overflow. For reliable, leak-free drainage, the OEM pan is the correct fit.

Installation Difficulty

Moderate. Requires accessing the coil section, disconnecting the drain line, sliding out the old pan, and seating the replacement with the proper slope toward the drain. Plan 45–75 minutes. Disconnect power, clear and flush the drain line during the swap, and confirm no standing water remains before closing the cabinet.
