OEM Goodman Drain Pan Gasket for WAHMS1824P4ACA — 0154A00000BL

The genuine Goodman 0154A00000BL Drain Pan Gasket is a factory replacement seal for the WAHMS1824P4ACA wall-mount air handler (1.5–2 ton class). This gasket sits between the condensate drain pan and the cabinet, creating a watertight joint that keeps condensate flowing to the drain instead of seeping into the cabinet or onto the wall behind the unit.

OEM vs. Generic

This is a true OEM Goodman part cut to the exact pan profile, so it seats correctly the first time and resists compression set over years of service. Universal foam tape can be trimmed to fit, but inconsistent thickness often leads to pinhole leaks and re-work. For a reliable, leak-free seal we recommend the OEM gasket.

Install difficulty

Easy — peel, position, and press. Typically a 5–10 minute job once the drain pan is exposed. No special tools required.
