The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner component engineered specifically for the AMES921205DNAA gas furnace and other compatible Goodman/Amana models. The orifice meters the precise volume of natural gas delivered to each burner, ensuring a clean, efficient flame and correct BTU output. A worn, corroded, or incorrectly sized orifice causes lazy flames, sooting, delayed ignition, and reduced efficiency — replacing it with the factory-spec part restores proper combustion.
Gas orifices are drilled to a specific diameter that determines the gas flow rate. The genuine OEM 10716005 is drilled to the exact factory specification for this furnace's manifold pressure and altitude rating, guaranteeing safe combustion. Aftermarket orifices often vary in bore size, which can over- or under-fire the burner and create a safety hazard. For a gas-metering part, we strongly recommend the OEM component.
Easy — the orifice threads into the manifold and typically requires only a wrench, but any work on a gas system should be performed by a licensed HVAC technician who can leak-check the connection and verify the flame after installation.
Always shut off gas and power before servicing. If you are unsure this is the correct orifice for your unit, contact us at info@nationalhvacparts.com with your full model and serial number.
