The Goodman 0154F00004 gasket is a genuine OEM sealing component for the ACVC800603BXAB gas furnace. Furnace gaskets create an airtight seal between mating combustion-side components — such as the burner assembly, inducer, or heat exchanger collector box — preventing flue gas leakage and maintaining correct combustion pressure. A cracked or compressed gasket can cause combustion air leaks, pressure-switch faults, and potential flue-gas escape, so the gasket should always be replaced whenever the sealed component is removed.
This genuine OEM gasket is die-cut to the exact bolt pattern and thickness required for a leak-free seal. Generic or trimmed substitute gaskets risk improper compression and combustion leaks. For safety-critical sealing, OEM is strongly recommended.
Moderate — requires removing the sealed combustion component and cleaning the mating surfaces before fitting the new gasket. Disconnect power and gas before servicing. Estimated time: 30–60 minutes.
