The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) designed for the AMH80903BXCC gas furnace. The orifice meters the precise volume of natural gas delivered to each burner, setting the flame size and total BTU input for the appliance. A correctly sized orifice is critical for clean, efficient combustion and safe operation — an incorrect drill size can cause sooting, delayed ignition, or dangerous over-firing.
Orifice sizing is measured in thousandths of an inch, and the OEM 10716003 is drilled to Goodman's exact specification for this furnace at standard natural gas pressure. Generic or hand-drilled orifices frequently deviate, throwing off the fuel-air ratio. For combustion components, always use the factory-matched OEM part.
Requires removing the manifold or burner assembly and threading the orifice into the correct port. Combustion work should be verified with a manometer and combustion analyzer. If you are not comfortable checking gas pressure and flame quality, use a licensed HVAC technician.
