The Goodman 10716005 Natural Gas Orifice is a genuine OEM metering component built for the AMEC800403ANAA 80% AFUE gas furnace and compatible Goodman/Amana models. The orifice is precision-drilled to deliver the exact natural-gas flow the manifold and burners require, ensuring a clean, efficient flame and correct BTU input. A worn, corroded, or incorrectly sized orifice causes lazy flames, delayed ignition, sooting, and poor heat output — replacing it with the factory-spec part restores safe, efficient combustion.
This is the genuine OEM Goodman orifice, drilled to the manufacturer's exact orifice-size specification for your furnace's BTU rating. Generic orifices may vary in bore diameter, leading to over- or under-firing. For a gas-metering component, we strongly recommend OEM to guarantee correct combustion and safety.
Easy — screws into the manifold with a wrench. Always shut off the gas supply and power before servicing, and confirm the orifice size matches your fuel type. Gas work should be performed by a qualified technician where required by local code.
