The Goodman 0154F00004 is a genuine OEM combustion/burner box gasket engineered for the AMH80804BXBC 80,000 BTU gas furnace and compatible Goodman/Amana models. This gasket forms the high-temperature seal between the burner assembly and the heat exchanger, preventing flue-gas leakage and maintaining safe, efficient combustion. A cracked or compressed gasket is a common cause of nuisance flame-sensor faults and combustion odors, making this an inexpensive but critical repair part.
OEM vs. Generic: The genuine OEM 0154F00004 is die-cut to factory tolerances and rated for the exact heat exchanger flange it seals. Generic universal gasket material can be trimmed to fit but risks improper compression, gaps, and premature failure — for a combustion-side seal we strongly recommend the OEM part.
Install difficulty: Easy to Moderate — requires removing the burner assembly and basic hand tools. Always shut off gas and power before service; a licensed HVAC technician is recommended for combustion-side work.
