The Goodman 0154F00004 is a genuine OEM high-temperature gasket seal for the Amana/Goodman AMH80804BXBA gas furnace. It creates an airtight, heat-resistant seal between mating combustion components—preventing flue-gas leakage, maintaining proper draft, and protecting combustion efficiency. Reusing a crushed or hardened gasket after servicing the burner assembly or collector box is a common source of rumbling, poor ignition, and safety-code failures.
OEM vs. Generic: The die-cut OEM gasket matches your furnace's flange bolt pattern and thickness exactly, ensuring a proper compression seal. Trimming a universal sheet gasket rarely delivers the same fit and risks combustion-air leaks. For sealing integrity, OEM is the safe choice.
Install difficulty: Moderate (2/5). Requires partial disassembly of the burner or collector assembly to access the sealing surface. Always replace gaskets whenever the assembly is opened. Budget 30–45 minutes and confirm no gas leaks afterward with a soap test.
