OEM Goodman 23x20 Vertical Drain Pan for ARPF364216AB — B1756020L

Goodman B1756020L Vertical Drain Pan (23 x 20 in)

The B1756020L is a genuine OEM vertical condensate drain pan engineered specifically for Goodman ARPF364216AB air handlers. It captures and channels condensate away from the coil during cooling operation, protecting the cabinet, blower, and surrounding ductwork from water damage and mold. Because it is a factory part, the drain ports, mounting tabs, and overall 23 x 20 in footprint line up exactly with the original — no trimming, drilling, or shimming required.

OEM vs. Generic

This is a genuine Goodman OEM pan, guaranteeing an exact fit and proper condensate slope. Universal aftermarket pans are often sold cheaper but frequently require modification and can leak if the drain location or depth does not match. For a leak-free installation and to preserve any remaining manufacturer warranty, the OEM B1756020L is the recommended choice.

Installation Difficulty

Moderate. Replacement requires removing the access panel and partially pulling the coil to seat the pan. Most experienced DIYers can complete it in 30–60 minutes; if you are uncomfortable handling the evaporator coil, a licensed HVAC technician is recommended.
