The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner component engineered for the Goodman GKS90905DXAD 90%+ AFUE gas furnace. The orifice meters the precise flow of natural gas into each burner, ensuring a clean, efficient flame and correct BTU output. A worn, corroded, or incorrectly sized orifice causes lazy yellow flames, sooting, delayed ignition, and poor heat exchanger performance — replacing it with the exact factory part restores safe, spec-accurate combustion.
Because an orifice controls gas flow, drill-size accuracy is critical for safety. The genuine OEM 10716003 is bored to Goodman's exact specification for your model, guaranteeing correct BTU input. Generic or field-drilled orifices risk over- or under-firing, which can trip limit switches or damage the heat exchanger. For a combustion component, we strongly recommend OEM.
Moderate — requires shutting off gas and power, removing the burner assembly, and swapping the orifice. Best performed by an HVAC professional. Always leak-test connections after installation.
