OEM Goodman 23 x 20 in. Vertical Drain Pan for ARPF364216AC — B1756020L

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

The Goodman B1756020L is a genuine 23" x 20" outside-dimension vertical condensate drain pan built as an exact-fit replacement for the ARPF364216AC air handler in upflow/downflow (vertical) installations. The drain pan captures condensate from the evaporator coil and channels it to the drain line. A cracked, warped, or corroded pan leads to water leaks, overflow, and costly water damage. This OEM pan restores proper drainage and fit.

OEM vs. Generic

Aftermarket pans often differ in depth, drain-port location, and footprint, causing standing water or misaligned drain connections. This genuine OEM pan matches the coil footprint and factory drain-fitting position, ensuring complete drainage and a leak-free seal exactly where the original sat.

Install Difficulty

Moderate — Requires pulling the evaporator coil to access and swap the pan, then reconnecting the condensate line and verifying slope to drain. Plan 45–75 minutes. Shut off power and have a wet/dry vac handy for residual water.
