The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud engineered for AMVC81005CXBA gas furnaces. The orifice precisely meters natural gas flow into each in-shot burner, setting the correct gas-air ratio for clean, efficient combustion. A worn, enlarged, or mismatched orifice causes improper flame, sooting, or reduced efficiency — using the correct OEM orifice keeps heating safe and on-spec.
This genuine OEM orifice is drilled to the exact bore size specified for this furnace and gas type, guaranteeing correct BTU input and clean combustion. Generic or wrong-size orifices can over- or under-fire the burner, creating a carbon-monoxide or efficiency risk. Match the orifice exactly — OEM is essential for gas metering.
Moderate to Advanced — requires accessing the manifold and gas components. Best performed by a licensed HVAC technician. Shut off gas and power, and verify input with a manometer after install.
