OEM Goodman 23x20 Vertical Drain Pan for ARUF049 Air Handler — B1756020L

The Goodman B1756020L Vertical Drain Pan is a genuine OEM condensate pan engineered for ARUF049-00A-1B air handlers and compatible Goodman/Amana vertical-mount models. Measuring 23 x 20 inches (outside dimension), it captures condensate from the evaporator coil and channels it to the drain line, protecting your equipment and surrounding structure from water damage. Cracked, corroded, or algae-clogged pans are a leading cause of overflow and water-stain service calls — replacing with the exact factory part restores proper drainage geometry the first time.

OEM vs. Generic

The genuine OEM pan matches the original mounting points, slope, and drain-port location exactly, so it seats flush and drains correctly with no field modification. Universal aftermarket pans often require trimming or shimming and can leave standing water that breeds mold. For a vertical coil, factory fit matters — choose OEM when you want a clean, leak-free install.

Installation

Difficulty: Moderate. Requires powering down the unit, removing the coil access panel, sliding out the old pan, and reseating the new one with the drain line reconnected. Most experienced DIYers complete it in 30–45 minutes; first-timers may prefer a technician. Always clear and flush the condensate line during replacement.
