The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud for the VMES960803BNAA gas furnace and compatible Goodman/Amana models. The orifice meters the exact volume of natural gas delivered into each burner tube, setting the furnace's BTU input and air-fuel ratio. A worn, corroded, or incorrectly sized orifice throws off the flame — causing sooting, delayed ignition, or under-firing — so replacing a damaged spud with the factory-drilled part is essential to safe, efficient combustion.
The OEM Goodman 10716005 is precision-drilled to the exact bore Goodman rated for this model's manifold pressure and altitude. Generic or hand-drilled orifices vary in bore diameter, directly changing gas input and combustion safety. On a gas-metering part, only the OEM spud guarantees correct firing rate.
Moderate (3/5) — Requires shutting off gas and power, removing the manifold or burner assembly, and threading the new orifice to spec. Should be performed by a qualified HVAC technician; a manometer check of manifold pressure is recommended after install.
