The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud for the AMVC950453BXBA modulating gas furnace and compatible Goodman and Amana models. This precision-drilled brass orifice meters the exact volume of natural gas delivered to each burner, setting the furnace's BTU input and ensuring a clean, efficient flame. A damaged, corroded, or incorrectly sized orifice causes poor combustion, sooting, delayed ignition, or reduced heat output.
Orifice bore size is engineered to your furnace's rated input and local gas pressure. The OEM orifice guarantees the correct drill size; a generic with the wrong bore over- or under-fires the burners, wasting fuel and creating a safety hazard. Always match OEM for gas components.
Moderate (2/5) — Requires gas-line work. Shut off gas and power, remove the manifold/burner as needed, unthread the old orifice, and torque the new one to spec. Leak-test all connections with soap solution before firing. If you are not comfortable working on gas, hire a licensed HVAC technician.
