The Goodman 0154F00002P is a genuine OEM gasket seal for the GKS90905DXAF high-efficiency gas furnace. This gasket forms the airtight seal between the burner box, coil, or manifold panel and its mating surface, keeping conditioned air, combustion gases, and inducer draft where they belong. A worn, brittle, or missing gasket leads to air leaks, whistling, reduced efficiency, and potential combustion-safety issues.
The genuine Goodman OEM gasket is die-cut to the exact panel footprint and rated for furnace-cabinet temperatures. Generic foam or felt substitutes may compress unevenly or degrade with heat, breaking the seal. For a leak-free, code-compliant repair we recommend the OEM part.
Easy (2/5). Power down the furnace, remove the affected panel, peel off the old gasket, clean the surface, and apply the new seal before reassembly. Roughly 15–20 minutes. Ensure the mating surface is clean and dry for full adhesion.
Confirm the part number against your furnace nameplate before ordering.
