The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud for Goodman and Amana AMS81005CXAD gas furnaces. Threaded into the manifold, the orifice meters the precise volume of natural gas delivered to each burner, ensuring a stable, correctly-sized flame for clean and efficient combustion. A worn, corroded, or incorrectly-sized orifice causes poor flame quality, sooting, delayed ignition, or nuisance flame-sensor lockouts.
The OEM 10716005 is drilled to the exact orifice diameter matched to your furnace's BTU input and gas type. Generic or mis-drilled orifices alter the gas flow rate, which can over- or under-fire the burner and create unsafe combustion. Always match orifice size to the rating plate.
Easy (2/5). Shut off the gas and power, remove the manifold or burner assembly, and thread the orifice in snugly — do not overtighten. Verify flame appearance and check for leaks with soap solution after install.
