The Goodman 10716003 is a factory-original natural gas burner orifice (spud) engineered for the WFD195090S4CAA gas furnace and compatible Goodman/Amana furnace platforms. This precision-drilled brass orifice meters the exact gas flow to each burner, ensuring a clean, efficient flame and correct BTU input. A worn, corroded, or incorrectly sized orifice is a leading cause of sooting, delayed ignition, and poor combustion — replacing it with the OEM spec part restores safe, rated performance.
Because an orifice controls the gas metering rate down to a thousandth of an inch, the OEM 10716003 guarantees the drill size matches your furnace's rated input — critical for combustion safety and CSA/AGA compliance. Generic or drilled-to-fit substitutes risk over-firing, incomplete combustion, or carbon monoxide production. For a fuel-metering component, we strongly recommend the genuine OEM part.
Moderate — the burner assembly must be removed and the orifice threaded into the manifold. Best performed by an HVAC technician who can verify manifold pressure and inlet gas pressure after replacement. Always shut off gas and power before service.
