The 10716005 is a genuine OEM natural-gas burner orifice (spud) for the Amana/Goodman AMVC800805CNAB two-stage, variable-speed 80% AFUE gas furnace. The orifice meters the precise volume of natural gas into each in-shot burner, setting the correct gas/air mixture for clean, efficient combustion. A worn, corroded, or incorrectly drilled orifice causes sooting, poor flame, and reduced efficiency. Always match the orifice drill size to your furnace rating and gas type — this is the natural-gas spud, not an LP conversion part.
The OEM orifice is drilled to the exact diameter Goodman specifies for this model's BTU input and manifold pressure. A generic or wrong-size orifice over- or under-fires the burner, risking sooting, rollout, or heat-exchanger stress. For a gas-metering component, OEM is strongly recommended.
Moderate (3/5). Shut off gas and power, remove the manifold or unthread the orifice, and install the correct spud. Verify manifold pressure with a manometer after service. Gas work should be performed by a licensed HVAC technician where required by local code.
Goodman and Amana use a shared OEM parts catalog; 10716005 is a direct fit for the Amana AMVC8 furnace.
