The Goodman 10716005 Natural Gas Orifice is a precision-drilled OEM burner spud made for the Amana/Goodman AMVC81005CNCA gas furnace. The orifice meters the exact volume of natural gas delivered into each burner, setting the flame size and BTU input. A correctly sized orifice is essential for clean, efficient combustion and safe carbon-monoxide levels—which is why the factory drill diameter must be matched precisely to your model and fuel type.
Orifice sizing is safety-critical. This genuine OEM spud carries the factory drill size for your model, ensuring proper gas flow and flame quality. Generic or mis-drilled orifices can cause sooting, delayed ignition, or dangerous over-firing. Always match OEM.
Moderate — Requires removing the burner assembly or manifold to access the orifice, then threading the new spud to spec. Shut off gas and power first, and leak-check all joints after reassembly. Recommended for experienced DIYers or a licensed technician.
