The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud that meters natural gas flow into the burner assembly of the GKS90904CXAH gas furnace and compatible Goodman/Amana models. The orifice bore is precision-drilled to deliver the exact BTU input the furnace was certified for, ensuring a clean, efficient flame and proper combustion. An incorrectly sized orifice causes sooting, delayed ignition, or dangerous over-firing.
OEM orifices are machined to the certified drill size for this furnace's rating and altitude. Generic orifices vary in bore diameter and thread quality, risking improper firing rate and combustion-safety issues. Because gas metering is safety-critical, always use the genuine OEM spud.
Moderate — requires shutting off the gas supply, removing the burner assembly, unthreading the old orifice, and torquing the new one to spec. This involves live-gas components, so a licensed HVAC or gas technician is recommended. A leak check with soap solution is mandatory after install.
