The genuine Goodman 10716003 Natural Gas Orifice is a factory-spec burner orifice engineered for the Goodman/Amana AMS80904BNAA gas furnace and other compatible 80% AFUE models. The orifice meters the precise volume of natural gas into each burner, so the correct drill size is critical to maintaining rated BTU input, a clean blue flame, and safe, efficient combustion. A worn, corroded, or incorrectly sized orifice can cause sooting, delayed ignition, or nuisance lockouts.
OEM vs. Generic: This is a genuine OEM Goodman orifice, drilled to the exact factory specification for your furnace's manifold pressure and BTU rating. Generic orifices are cheaper but often vary in bore diameter, which can throw off the air-fuel ratio and undermine both efficiency and safety. For a combustion component, we strongly recommend OEM.
Install difficulty: Easy — for a qualified technician. The orifice threads into the burner manifold and typically requires only a nut driver or wrench. Because this is a gas component, installation should be performed by a licensed HVAC professional, followed by a manifold pressure check and combustion analysis. Always shut off gas and power before servicing.
