The Goodman 0154F00004 Gasket is a genuine OEM sealing component for the Amana AMES800603BNAA gas furnace and compatible Goodman/Amana units. This gasket creates an airtight seal between the burner/manifold assembly and the heat exchanger, ensuring clean, efficient combustion and preventing flue-gas or air leakage that can trigger flame-sensing and pressure faults.
The OEM 0154F00004 is die-cut to the precise dimensions and bolt pattern of your furnace, guaranteeing a leak-free seal rated for combustion temperatures. Generic or cut-to-fit gaskets may not match the port geometry and can degrade prematurely, leading to air leaks and reduced efficiency.
Moderate (2 of 5). Requires removing the burner assembly to replace the gasket. Shut off gas and power, remove burners/manifold, clean the mating surfaces, seat the new gasket, and reassemble — typically 30–45 minutes for a competent DIYer or technician.
