The Goodman 0154F00004 Gasket is a genuine OEM sealing component engineered for the WFM18070S4BXCB furnace and other compatible Goodman and Amana gas furnace assemblies. This gasket forms the critical air- and gas-tight seal between mating surfaces such as the burner box, manifold, or heat exchanger flange, preventing combustion leakage and maintaining proper furnace efficiency and safe operation.
Manufactured from high-temperature, heat-resistant material, this gasket is built to withstand the thermal cycling of a working furnace without hardening, cracking, or losing its seal. Replacing a worn or brittle gasket restores factory-grade sealing and helps eliminate combustion odors, nuisance shutdowns, and heat loss.
This is a genuine OEM Goodman gasket cut to the exact factory dimensions and material spec. Generic aftermarket gaskets are typically cheaper but may use lower-grade material that degrades faster under heat and can leave gaps that leak combustion gases. For a sealing component on a gas appliance, we recommend the OEM part for guaranteed fit and safety.
Easy – Moderate. Replacement is straightforward for a qualified technician: shut off gas and power, remove the affected panel/burner assembly, clean the mating surface, and seat the new gasket. Because this is a combustion-side component on a gas furnace, installation should be performed by a licensed HVAC professional.
