The Goodman 10716005 is a genuine OEM natural gas orifice (spud) for Amana/Goodman gas furnaces, including the AMEC800805CXAA. The orifice threads into the manifold and meters the exact amount of gas delivered to each in-shot burner. Its precisely drilled bore sets the burner's BTU input, so using the factory-correct orifice is essential for a clean blue flame, proper efficiency, and safe combustion.
Orifice sizing is critical. This genuine OEM orifice is drilled to the manufacturer's specification for the correct BTU input at your altitude and gas type. An incorrectly sized generic spud can cause sooting, poor efficiency, delayed ignition, or dangerous over-firing. For a combustion component, OEM sizing is not optional.
Easy. Shut off gas and power, remove the burner assembly if needed, then unthread the old orifice and thread in the replacement. About 15–20 minutes. Confirm the flame appearance after installation. If converting fuel types, use the proper conversion kit instead.
Turn off gas and electrical power before servicing. Verify the part number and gas type before ordering.
