The Goodman 10716003 Natural Gas Burner Orifice is a genuine OEM metering jet engineered for the Goodman/Amana WFM18070S4BXCB gas furnace. This precision-drilled brass orifice meters the exact volume of natural gas delivered to each burner, ensuring a stable, correctly proportioned flame and efficient, safe combustion. A worn, corroded, or incorrectly sized orifice causes lazy yellow flames, sooting, delayed ignition, and reduced heat output — replacing it with the factory-spec part restores rated BTU performance.
This is a genuine Goodman OEM orifice, drilled to the manufacturer's exact bore diameter for the model's rated input. Generic or universal orifices often have incorrect drill sizes that alter the air-fuel ratio, risking incomplete combustion and carbon monoxide production. For a combustion component, OEM fit is strongly recommended.
Moderate — Requires shutting off gas, removing the burner assembly, and a manifold wrench. Because this affects combustion, we recommend installation and combustion verification by a licensed HVAC technician.
