The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud precision-drilled to meter the exact natural gas flow required by Amana/Goodman AMH80903BXCB 80% AFUE furnaces. The orifice threads into the manifold and directs a metered stream of gas into each burner, ensuring clean ignition, a stable blue flame, and rated BTU output. A worn, corroded, or incorrectly drilled orifice causes lifting flames, sooting, incomplete combustion, and reduced efficiency.
The orifice bore diameter is fuel- and BTU-specific. This genuine OEM spud is drilled to Goodman's exact specification for correct gas pressure and flame quality. Generic orifices with slightly off bore sizes can under- or over-fire the furnace, risking soot, delayed ignition, or unsafe combustion. Always match orifice to your gas type and rating.
Easy (2 of 5). Shut off gas supply, remove the burner assembly, and thread the orifice into the manifold with a wrench — do not overtighten. Verify flame quality after install. If converting fuel types, professional setup and combustion analysis are required.
