The Goodman 10716003 Natural Gas Burner Orifice is a genuine OEM metering spud for the Goodman GKS90704CXAD gas furnace and compatible Goodman/Amana models. The orifice threads into the manifold and precisely meters the flow of natural gas into each burner, setting the correct BTU input and ensuring a clean, efficient flame. A worn, corroded, or incorrectly-sized orifice causes sooting, poor combustion, or improper firing rate.
Orifice sizing is critical — the drilled bore diameter directly sets the furnace's firing rate. The genuine Goodman OEM orifice is machined to the exact factory drill size for your model's rated BTU input. Generic or mismatched orifices can over- or under-fire the furnace, risking incomplete combustion and carbon monoxide. Always match OEM for gas-carrying parts.
Moderate (3/5). Requires shutting off the gas supply and power, removing the burner assembly, and using a wrench to swap the orifice on the manifold. Best performed by an experienced DIYer or licensed technician. Always leak-test connections with soap solution and verify flame quality after installation.
