The genuine Goodman 10716003 natural gas orifice (also called a spud) is the precision-machined jet that meters the exact flow of natural gas into each burner of your AMVC950905DXAC two-stage variable-speed furnace. The orifice bore is factory-drilled to a specific size for natural gas at standard supply pressure, so replacing a worn, corroded, or incorrectly drilled orifice restores clean, quiet, efficient combustion and the correct flame appearance across every burner.
Because an orifice controls gas flow, bore diameter is safety-critical. This genuine OEM Goodman orifice is drilled to the exact factory specification, guaranteeing correct BTU input and combustion. A generic or mis-drilled orifice can cause sooting, delayed ignition, sensor lockouts, or over-firing — we recommend OEM for any gas-metering component.
Replacement requires shutting off the gas supply and power, removing the burner assembly, and reinstalling the orifice to the correct torque. Best performed by a qualified HVAC technician. Always verify manifold pressure and check for leaks after service. Match the number stamped on your old orifice before installing.
