The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner component engineered for the AMH81005CNAA gas furnace and other compatible Goodman and Amana models. This precision-drilled brass orifice (spud) meters the exact volume of natural gas delivered to the burner, ensuring a clean, efficient flame and proper BTU output. A worn, corroded, or incorrectly sized orifice can cause sooting, delayed ignition, or poor combustion efficiency — installing the correct OEM part restores factory performance.
Genuine OEM orifices are drilled to Goodman's exact specification for your furnace's manifold pressure and BTU rating. Generic or universal orifices may deviate in drill size, leading to over- or under-firing, safety lockouts, or nuisance faults. For a gas-metering part, we strongly recommend OEM.
Moderate — requires shutting off gas, removing the burner, and threading in the orifice. Because this is a gas component, installation should be performed by a qualified HVAC technician who can leak-check and verify manifold pressure.
