The Goodman 0154F00004 Gasket is a genuine OEM sealing component for the ADVC80603BNBA gas furnace and compatible Goodman/Amana equipment. This gasket forms an airtight, heat-resistant seal between mating combustion-side surfaces, preventing flue-gas and air leakage that would otherwise reduce efficiency, trigger pressure-switch faults, or create a safety hazard. Made from the correct high-temperature material and cut to the exact factory profile, it restores the original seal integrity whenever the burner or collector assembly is opened for service.
The OEM 0154F00004 is die-cut to the precise dimensions and bolt pattern of your furnace, ensuring an even, full-contact seal. Generic or hand-cut gasket material rarely matches the profile, which can leave gaps that leak combustion gases and cause intermittent pressure-switch lockouts. For a combustion seal, OEM fit is essential for safe, efficient operation.
Difficulty: Moderate (3/5). Replacement requires partially disassembling the burner or collector box, scraping off all old gasket residue, and seating the new gasket cleanly before torquing fasteners evenly. Because it involves the combustion system, we recommend a qualified HVAC technician perform the work and verify a leak-free seal and correct combustion afterward. Plan for 45–90 minutes depending on access.
