The Goodman 0154A00000BL Drain Pan Gasket is a genuine OEM sealing component for the WAHMS3743P4ACA air handler. This gasket creates a leak-tight seal between the drain pan and the cabinet or coil assembly, ensuring condensate is captured and routed to the drain line instead of seeping into the unit. A hardened, torn, or missing gasket is a frequent cause of water leaks, cabinet rust, and water-overflow safety trips. Replacing it with the factory gasket restores a watertight seal.

OEM vs. Generic

The genuine Goodman gasket is cut to the exact profile and thickness needed to seal the WAHMS3743P4ACA drain pan. Generic foam or universal gasket stock may compress unevenly or fail to seal, leading to slow leaks. OEM guarantees correct compression and a reliable, long-lasting seal.

Installation Difficulty

Easy. Peel and place against the pan flange after cleaning the mating surface. Plan 15–30 minutes; no special tools required. Ensure the surface is dry and free of old adhesive for best adhesion.
