The Goodman 10716003 is a natural gas burner orifice (spud) engineered for the Goodman GKS90703BXAF gas furnace and compatible GKS90 series models. This small brass component meters the precise volume of natural gas delivered to each burner, ensuring a clean, stable flame and correct BTU input. A worn, corroded, or incorrectly drilled orifice is a leading cause of sooting, delayed ignition, and poor combustion efficiency.
The genuine OEM 10716003 is drilled to the exact factory orifice size for your furnace's rated input, guaranteeing safe combustion and full efficiency. Generic or field-drilled orifices risk over- or under-firing, which can void warranties and create carbon monoxide hazards. For a gas-metering part, OEM is strongly recommended.
Moderate — requires shutting off gas, removing the burner assembly, and correct torque on reassembly. Gas connections should be leak-tested. Best performed by an EPA/NATE-certified HVAC technician.
