OEM Goodman 23 x 20 in Vertical Drain Pan for ADPF30421BA — B1756020L

The Goodman B1756020L Vertical Drain Pan is a genuine OEM condensate pan with a 23 x 20 inch outer-dimension footprint, designed for the Goodman ADPF30421BA cased evaporator coil and compatible vertical air handler applications. The drain pan collects condensate from the cooling coil and channels it to the drain line, protecting your furnace, ductwork, and surrounding structure from water damage and mold. A cracked, rusted, or warped pan leads to overflow, ceiling stains, and costly repairs.

OEM vs. Generic

This genuine Goodman OEM pan is molded to the precise coil footprint and drain-port location of your unit, ensuring proper slope and a leak-free fit. Generic pans may not align with the coil or drain connection, allowing standing water and overflow. For a leak-critical component, OEM is strongly recommended.

Installation Difficulty

Moderate (3/5). Requires removing the access panel and sliding the coil to swap the pan, then reconnecting the condensate drain. Best performed by an HVAC technician to verify proper slope and a sealed drain connection. Shut off power and clear the drain line before service.
