The Goodman 10716003 Natural Gas Orifice is a genuine OEM precision-drilled burner spud that meters natural gas into the burner venturi of your AMH80403ANAA 80% AFUE gas furnace. The orifice bore diameter sets the fuel input rate and gas/air mixture, making it critical for clean, efficient combustion and correct BTU output. A worn, corroded, or debris-blocked orifice can cause a lazy yellow flame, sooting, delayed ignition, or reduced heat output.
The genuine OEM 10716003 is drilled to the exact orifice size engineered for this furnace's input rating and manifold pressure. Using the wrong drill size — common with generic spuds — overfires or underfires the furnace, wastes fuel, and can create a dangerous combustion condition. For gas-metering components, always match the factory OEM part.
Moderate (3/5). Requires shutting off the gas supply, removing the manifold or burner, and threading in the new orifice with a nut driver or wrench. A gas leak check with soap solution afterward is mandatory. Turn off gas and power before servicing. If in doubt, use a licensed HVAC technician — improper gas metering is a safety hazard.
