OEM Goodman 23x20 in Vertical Drain Pan for ARPF486016CA — B1756020L

The Goodman B1756020L is an OEM vertical condensate drain pan engineered as a direct-fit replacement for ARPF486016CA air handlers and compatible Goodman/Amana coil cabinets. When the original pan cracks, corrodes, or develops a slow leak, this factory part restores proper condensate capture and channels water cleanly to the drain line—preventing overflow, water damage, and microbial growth inside the cabinet.

OEM vs. Generic

This is a genuine Goodman OEM pan, molded to the exact cabinet footprint so it seats flat and aligns with the existing drain connections. Generic universal pans often require trimming, shimming, or re-routing the drain line and can leave gaps that allow water to bypass the pan. For a leak-free seal and a guaranteed fit, OEM is the safe choice.

Installation

Difficulty: Moderate. Requires removing the coil/blower assembly to access and swap the pan. Plan for basic hand tools, a wet/dry vac, and roughly 45–90 minutes. We recommend a licensed HVAC technician confirm the float switch and drain trap while the unit is open.
