The OEM Goodman 10716005 natural gas burner orifice (spud) is a factory-authorized part for the Amana/Goodman AMVC961205DNBA modulating variable-speed 96% AFUE gas furnace. Threaded into the manifold, it precisely meters natural gas flow to each main burner for correct BTU input, clean combustion, and proper flame characteristics.
Orifice bore diameter is drill-size critical — a generic or wrong-size spud over- or under-fires the burner, causing sooting, delayed ignition, or nuisance lockouts. The genuine 10716005 is machined to Goodman's exact NG drill spec for the manifold pressure this furnace is rated for.
Moderate (3/5). Requires shutting off gas, removing the manifold or burners, and swapping orifices with a nut driver, then leak-checking and verifying manifold pressure. Recommended for HVAC professionals; confirm the orifice size matches your nameplate before converting between fuels.
