The Goodman 10716003 Natural Gas Orifice (burner spud) is a genuine OEM component that meters the flow of natural gas into each burner of the GKS91155DXAD gas furnace. The precision-drilled orifice is factory-sized to deliver the correct BTU input and air/fuel mixture for clean, efficient, safe combustion at your furnace's rated capacity.
A damaged, corroded, or incorrectly sized orifice causes poor flame quality, sooting, delayed ignition, or under/over-firing. Using the exact OEM orifice ensures the burner fires as designed and keeps the furnace operating within its listed specifications.
OEM vs. Generic: Orifice drill size directly controls firing rate. A generic or wrong-size orifice can over-fire the furnace (safety hazard, cracked heat exchanger) or under-fire it (poor heat, condensation). Always match the OEM spud to your gas type and altitude — this is the correct natural-gas orifice for the GKS91155DXAD.
Install Difficulty: Moderate (3 of 5). Requires shutting off gas and power, accessing the manifold/burner assembly, and threading the orifice to the correct torque. Improper gas work is dangerous — professional installation is recommended, and a combustion/leak check should follow.
