OEM Goodman 23x20 Vertical Drain Pan for ARUF048 — B1756020L

The Goodman B1756020L Vertical Drain Pan is a genuine OEM condensate pan sized at 23 x 20 inches outside dimension for use in vertical (upflow/downflow) ARUF048-00A-1A air handler installations. It captures condensate from the evaporator coil and channels it to the drain connection, protecting the cabinet base, ductwork, and surrounding structure from water damage. A cracked, corroded, or warped drain pan is a frequent source of overflow leaks and should be replaced with a correctly sized OEM pan.

OEM vs. Generic

This OEM pan is molded to the exact ARUF048 cabinet footprint and drain-port locations, so it drops in without modification and aligns with the factory drain plumbing. Universal aftermarket pans require field adaptation and frequently mismatch the drain outlet position, risking standing water and overflow. The OEM pan is the dependable fit.

Installation Difficulty

Moderate. Requires removing the coil/blower section to access and swap the pan, then re-connecting the condensate line. Power down before service. Estimated time: 45–90 minutes. Recommended for experienced DIYers or a technician.
