Goodman 0154A00000BL Drain Pan Gasket

The Goodman 0154A00000BL is a genuine OEM drain pan gasket designed for WAHMS3642P4ACA air handlers. This gasket forms the watertight seal between the condensate drain pan and the cabinet or coil assembly, ensuring all condensate is captured and routed to the drain line instead of seeping into the unit base. A fresh gasket is inexpensive insurance against the water damage, rust, and mold that a failed seal can cause.

Specifications

Function: Condensate drain pan sealing gasket
Material: Closed-cell foam / EPDM seal stock
Resists moisture, mildew, and compression set
Fits: Goodman WAHMS3642P4ACA air handlers
OEM part number: 0154A00000BL

OEM vs. Generic

The genuine Goodman gasket is die-cut to the exact pan profile and thickness, so it compresses evenly and seals on the first install. Generic foam stock cut to size rarely matches the compression rating and can leak as it ages. At this price, OEM is the obvious choice.

Installation Difficulty

Easy. Peel the old gasket, clean the mating surface, and apply the new seal during routine drain pan service. Adds only a few minutes. Best replaced any time the drain pan is removed.
