The Goodman 10716005 is a genuine OEM natural gas burner orifice (spud) designed for the AMS81005CXAA gas furnace and compatible Goodman and Amana models. This precision-drilled brass fitting threads into the manifold and meters the exact volume of natural gas delivered to each burner. The orifice diameter is factory-matched to the furnace's BTU rating and inlet pressure, ensuring a stable, correctly sized flame for clean, efficient combustion.
Orifice drill size is critical — even a small deviation changes the gas flow rate, causing sooting, poor efficiency, or unsafe combustion. This OEM orifice is drilled to Goodman's exact specification for the AMS81005 platform. Generic or mislabeled orifices can be off by a drill number and are not worth the risk on a gas appliance.
Easy to Moderate (2/5). The orifice unscrews from the manifold with a socket or wrench once the burner assembly is accessed. Shut off gas and power first, verify the correct fuel type, and check for leaks with soap solution after reinstalling. Confirm orientation and that the burner seats properly before firing.
