The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud for the ADVC80603BNAA gas furnace. The orifice precisely meters natural gas into each burner tube, controlling flame size and combustion efficiency. A damaged, corroded, or debris-clogged orifice produces uneven flames, poor heat output, sooting, or ignition problems — all corrected by fitting the factory-specified spud.
This genuine Goodman OEM orifice is drilled to the exact size the ADVC80603BNAA burner requires. Substituting an incorrectly sized generic orifice changes the firing rate and can cause over-firing or incomplete combustion. For gas metering, the OEM size is the safe choice.
Moderate — Requires turning off the gas supply, accessing the manifold, and swapping the orifice with a wrench. Gas work is best handled by a licensed HVAC technician, and all connections must be leak-tested before returning the unit to service.
