OEM Goodman 23 x 20 Vertical Drain Pan for ARPF374316CA — B1756020L

The Goodman B1756020L Vertical Drain Pan is a genuine OEM condensate pan measuring 23 x 20 inches OD, engineered for vertical-configuration ARPF374316CA air handlers. It collects condensate from the evaporator coil and channels it to the drain line, protecting the cabinet, ductwork, and surrounding structure from water damage. Cracked, warped, or algae-clogged pans are a leading cause of ceiling stains and water alarms — this exact-fit pan restores proper drainage.

OEM vs. Generic

OEM pans are molded to the exact footprint, drain-port location, and slope of the original, so condensate flows correctly and the coil seats properly. Generic pans risk misaligned drain ports, poor slope, and standing water that breeds mold. For a sealed, leak-free system, the OEM pan is the correct choice.

Installation Difficulty

Moderate (3 of 5). Disconnect power and shut off the condensate line. Remove the coil or access panel as needed, swap the pan, reconnect the drain with proper slope, and verify with a water test before restoring service. Basic tools and 30–45 minutes are typical.
