OEM Goodman 23 x 20 in Vertical Drain Pan for ASPF303616BA — B1756020L

The Goodman B1756020L Vertical Drain Pan is a genuine OEM condensate pan measuring 23 x 20 inches (OD), engineered for vertical-configuration installs of the Goodman ASPF303616BA air handler. The pan collects condensate from the evaporator coil and channels it to the drain line, protecting the cabinet, ductwork, and surrounding structure from water damage. A cracked, rusted, or warped pan leads to overflow, leaks, and mold — replacing it with the exact OEM part restores reliable drainage and a watertight fit.

OEM vs. Generic

This genuine Goodman OEM pan is molded to the exact coil footprint and drain-port location of the ASPF303616BA. Generic or universal pans often misalign with the coil rails and drain fitting, causing standing water and overflow. OEM guarantees correct slope, fit, and drainage.

Installation Difficulty

Moderate — requires accessing and lifting the evaporator coil to slide out the old pan. Disconnect power, then transfer and reconnect the drain line. Plan 45–60 minutes; flush the drain line while the unit is open.
