OEM Goodman 23x20 Vertical Drain Pan for ARPF364216CA — B1756020L

The Goodman B1756020L Vertical Drain Pan is a genuine OEM condensate pan measuring 23 x 20 inches OD, designed for the ARPF364216CA air handler in vertical (upflow/downflow) configurations. It collects condensate draining off the evaporator coil and channels it to the drain connection, keeping water out of the cabinet and away from the structure.

Cracked, warped, or algae-clogged pans are a leading cause of ceiling stains, water damage, and float-switch trips. This OEM replacement restores the correct pan geometry and slope so condensate drains cleanly every cycle.

OEM vs. Generic

This genuine OEM pan is molded to the exact cabinet footprint and drain-port location of the ARPF364216CA, so it seats correctly and aligns with the existing drain line. Generic pans rarely match the slope or port position, risking standing water and leaks. OEM is the reliable choice.

Install Difficulty

Moderate (3 of 5). Requires removing the coil/access panel, disconnecting the drain line, sliding out the old pan, fitting the new pan with proper slope, and reconnecting the drain. Plan 45–60 minutes; verify a clean drain test before closing up.
