The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud that meters fuel flow into the in-shot burners of your Goodman ADVC81005CNAA gas furnace. The orifice drill size sets the BTU input per burner, so it must precisely match the furnace's rated capacity and fuel type. A worn, plugged, or incorrectly-sized orifice causes lazy flames, sooting, under-firing, or over-firing.
The OEM Goodman orifice is drilled to the exact metering size specified for this furnace at its rated altitude and manifold pressure. Generic or mis-drilled orifices change the BTU input, risking incomplete combustion, high CO, or nuisance limit trips. For any gas-metering part, genuine OEM sizing is essential to safe operation.
Moderate. Roughly 30–45 minutes. Shut off gas and power, remove the burner assembly to access the manifold, and thread the new orifice into the correct port. Because this affects fuel metering and combustion safety, we recommend a licensed HVAC technician verify manifold pressure and flame quality after installation.
