The Goodman 10716003 natural gas burner orifice (spud) is a genuine OEM metering component for the AMH80905CXCB gas furnace and compatible Goodman/Amana models. Threaded into the gas manifold, the orifice precisely regulates the volume of natural gas delivered to each in-shot burner. Its drilled bore size sets the furnace's BTU input, so using the correct orifice is essential for safe, efficient, and code-compliant combustion.
The OEM 10716003 is drilled to the exact bore diameter certified for this furnace at its rated altitude and manifold pressure. Generic orifices vary in drill size and thread quality; an incorrect bore can over- or under-fire the burner, risking sooting, short cycling, or heat-exchanger stress. For a gas-metering part, OEM is the safe choice.
Easy. Shut off gas and power, remove the manifold or unthread the individual orifice with a nut driver, and install the replacement finger-tight plus a snug turn. About 10–15 minutes. Always leak-check with soapy solution and confirm a clean blue flame afterward.
