The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) for the GKS90703BXAE gas furnace and compatible Goodman/Amana 90-series models. This precision-drilled brass orifice meters the exact volume of natural gas delivered to each burner, controlling the flame size and BTU input the furnace is rated for. A damaged, corroded, or incorrectly sized orifice causes poor combustion, sooting, delayed ignition, or an under/over-fired furnace—so using the correct OEM orifice is essential for safe, efficient heating.
Orifice bore diameter directly determines gas flow and firing rate. The genuine Goodman 10716003 is drilled to the manufacturer's exact specification for this furnace, ensuring correct BTU input and clean combustion. Generic orifices with an incorrect drill size can under- or over-fire the unit, creating efficiency and safety problems. OEM is strongly recommended for any gas-metering component.
Moderate (3/5). Requires shutting off the gas supply, removing the manifold or burner, threading in the correct orifice, and leak-checking all connections on restart. If you are not comfortable working with gas piping, have a licensed HVAC technician perform the replacement.
Always shut off gas and power before servicing your furnace, and leak-test after installation.
