The Goodman 10716005 natural gas orifice (burner spud) is a genuine OEM component for VMES800603AXAA gas furnaces and compatible Goodman/Amana models. The orifice meters the precise volume of natural gas into each in-shot burner, setting the furnace's BTU input and flame quality. A damaged, corroded, or incorrectly sized orifice causes over- or under-firing, sooting, or a lazy yellow flame — replacing it with the exact OEM spud restores rated performance.
The OEM Goodman 10716005 is factory-drilled to the exact diameter matched to this furnace's manifold pressure and altitude rating. Generic or mis-drilled orifices change the BTU input and can create dangerous combustion conditions. For any gas-metering part, OEM is strongly recommended.
Replacement requires shutting off the gas supply, unscrewing the old orifice from the manifold, and threading in the matching spud — do not overtighten. After install, verify manifold pressure and confirm a clean blue flame. Gas orifice work must be performed by a licensed HVAC professional and checked with a combustion analyzer.
