The Goodman 0154F00004 Gasket is a genuine OEM high-temperature sealing gasket for the AMVC800603BXAA gas furnace. It creates an airtight seal at the combustion or manifold interface, preventing flue-gas leakage and maintaining the negative pressure the induced-draft system depends on. A compromised gasket can allow leaks that trigger pressure-switch faults or safety lockouts.
The OEM 0154F00004 is die-cut to the precise bolt pattern and thickness of your furnace's sealing surface, ensuring a complete seal on the first fit. Generic or trimmed-to-fit gaskets often leak at the edges and degrade quickly under combustion heat. For a safe, lasting seal, choose genuine OEM.
Moderate (2/5). Requires removing the mating component, cleaning old gasket residue from both surfaces, and torquing fasteners evenly. Shut off power and gas first. Typical time: 25–40 minutes.
