The Goodman 10716003 Natural Gas Orifice is a factory OEM replacement burner orifice engineered for the Goodman GKS90904CXAG gas furnace and compatible GKS90-series models. The orifice meters the precise volume of natural gas delivered to each burner, ensuring a clean, stable flame and the correct BTU input your furnace was designed for. A worn, clogged, or incorrectly sized orifice causes poor ignition, sooting, delayed heat, or a lockout on the flame sensor.
This is a genuine Goodman OEM orifice, drilled to the exact factory bore size for your furnace's rated input. Generic or universal orifices are often mis-drilled, leading to over- or under-firing, condensation in the heat exchanger, and premature failure. For a combustion component, exact-fit sizing is critical to safety and efficiency — we recommend the OEM part.
Moderate — Requires shutting off gas, removing the burner assembly, and matching orifice position. Best performed by a licensed HVAC technician; improper installation can affect combustion safety. Verify part number against your unit before ordering.
