OEM Goodman Vertical Drain Pan for WAHMS1931P4ABA — B1756017L

The Goodman B1756017L is a genuine OEM vertical drain pan engineered to collect and channel condensate in Goodman air handlers, including ARUF036 and ARUF042 models and the WAHMS1931P4ABA air handler. A cracked, corroded, or warped drain pan is one of the most common causes of water leaks, ceiling stains, and float-switch shutdowns — installing the factory-spec pan restores proper drainage and protects the equipment and surrounding structure.

OEM vs. Generic

This is a genuine Goodman OEM pan, molded to the exact dimensions and drain-port geometry of the original. Generic or universal pans frequently misalign with the coil and existing drain lines, leading to overflow and repeat service calls. The OEM part drops in without modification and preserves your manufacturer fit.

Installation Difficulty

Moderate. Requires powering down the unit, removing the coil/access panel, swapping the pan, and re-seating the primary and secondary drain connections. Most experienced DIYers can complete it in 30–60 minutes; if you are unsure about coil handling or refrigerant lines, use a licensed HVAC technician.
