The Goodman 10716003 is a precision-drilled natural gas burner orifice engineered for GKS90703BXAA gas furnaces. The orifice meters the exact volume of natural gas delivered to each burner, ensuring a clean, efficient flame and correct BTU input. A worn, corroded, or incorrectly sized orifice causes poor combustion, sooting, delayed ignition, and lockouts — replacing it with the genuine OEM part restores factory performance.
Genuine Goodman orifices are drilled to the exact bore diameter specified for this furnace's gas valve pressure and manifold rating. Generic or mis-sized orifices can over- or under-fire the burner, risking incomplete combustion and carbon monoxide. For a safety-critical gas component, the OEM part is strongly recommended.
Moderate — requires shutting off the gas, removing the burner assembly, and verifying manifold pressure after replacement. Should be performed by a qualified HVAC technician.
