The Goodman 0154A00000BL Drain Pan Gasket is a genuine OEM seal for the condensate drain pan on the WAHMS3030P4ACA air handler. This gasket creates a watertight barrier between the drain pan and the cabinet, channeling condensate to the drain line instead of leaking into the unit or onto your floor. A hardened or torn gasket is a leading cause of water damage, rust, and mold around air handlers — a small part that prevents an expensive problem.
The factory Goodman gasket is die-cut to the exact pan profile and made from a closed-cell material that resists compression set in a constantly damp environment. Generic foam strip or universal gasket stock often shrinks, absorbs water, or fails to seal the corners, allowing slow leaks. OEM gives you a precise, durable seal the first time.
Made for the Goodman WAHMS3030P4ACA air handler drain pan. Confirm pan style and gasket footprint against your existing part before ordering.
Peel away the old gasket, clean the mating surface, and seat the new gasket along the pan flange. No tools or refrigerant work required — typically a 10-minute job. Power down the unit and clear the drain pan before starting.
