The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud for the Goodman/Amana AMS80403AXAC gas furnace. The orifice meters the precise volume of natural gas fed into each in-shot burner, setting the furnace's rated BTU input. A drilled, corroded, or incorrectly sized orifice throws off the air-fuel mixture, causing lazy yellow flames, sooting, delayed ignition, or under-firing. Installing the correct factory orifice restores clean, blue, on-spec combustion.
Genuine Goodman orifices are precision-drilled to the exact bore diameter certified for the AMS80403AXAC's input rating and manifold pressure. Generic or field-drilled orifices can over- or under-fire the furnace, producing dangerous carbon monoxide levels or nuisance limit trips. For a gas-metering part, always use the OEM drill size specified for your altitude and fuel.
Moderate (3/5) — Threads into the manifold and must be leak-checked and combustion-verified after install. Shut off gas and power, use the correct orifice for natural gas (do not reuse an LP spud), and confirm manifold pressure with a manometer. Professional installation recommended.
