The Goodman 0154A00000BL Drain Pan Gasket is a genuine OEM sealing gasket for the condensate drain pan on WAHME1830P4ACA and compatible Goodman/Amana air handlers. The gasket creates a watertight seal between the drain pan and the cabinet or coil base, preventing condensate from bypassing the pan and leaking into the unit or onto the floor. A flattened, brittle, or torn gasket is a leading cause of nuisance water leaks and float-switch trips.
The OEM gasket is die-cut to the exact pan profile and thickness, so it compresses evenly and seals the first time. Generic foam strip is cheaper but rarely matches the contour, leaving gaps that weep. For a dependable, leak-free seal at a low price, the OEM gasket is the smart choice.
Easy. Peel away the old gasket, clean the mating surface, and press the new gasket into place before re-seating the pan — about 10–15 minutes. Cut power and clear any standing condensate first. Confirm the pan sits flush and drains freely after the gasket is installed.
