The Goodman B1756020L Vertical Drain Pan is a genuine OEM condensate pan sized at 23 x 20 inches (OD) for the AEPF303616BB air handler in vertical (upflow/downflow) configurations. It captures condensate from the evaporator coil and channels it to the drain line, protecting the cabinet, ductwork, and surrounding structure from water damage. A cracked, warped, or algae-clogged pan leads to overflow and costly leaks — a new pan restores proper drainage.

Dimensions: 23 in x 20 in outside diameter
Brand: Goodman
Equipment: Air Handler

OEM vs. Generic

The genuine Goodman OEM pan is molded to match the coil footprint and drain port locations exactly. Generic universal pans rarely line up with factory drain fittings and can leave gaps that allow condensate to bypass the pan. OEM ensures a leak-tight, drop-in fit.

Installation Difficulty

Moderate — Generally 45-60 minutes. Requires disconnecting power, removing the coil to access and swap the pan, then reconnecting drain lines. Best handled by an experienced DIYer or HVAC technician.
