OEM Goodman 23 x 20 in Vertical Drain Pan for ARPF364216BA — B1756020L

The Goodman B1756020L Vertical Drain Pan is a genuine OEM condensate pan sized at 23 x 20 inches (OD) for vertical-configuration ARPF364216BA air handlers. It captures condensate dripping off the evaporator coil and channels it to the drain line. Cracked, warped, or rusted pans are a leading cause of ceiling stains, water damage, and clogged secondary drains — installing the factory pan restores proper drainage and protects the equipment and the structure around it.

OEM vs. Generic

This OEM Goodman pan matches the exact footprint, slope, and drain-fitting location of the original. Generic pans rarely line up with the factory mounting standoffs and drain port, leading to pooling water and poor slope to the drain. The OEM part guarantees correct fit and drainage angle out of the box.

Installation Difficulty

Moderate (3/5). Requires pulling the coil to access and swap the pan, then reconnecting the condensate line and verifying drainage slope. Plan for 45–90 minutes. Shut off power and recover/secure refrigerant lines per code before disturbing the coil.
