The Goodman 10716003 Natural Gas Orifice (burner spud) is a genuine OEM metering component for the Goodman GCH950703BXAC gas furnace. The orifice controls the precise volume of natural gas fed to each burner, setting the firing rate and ensuring clean, efficient combustion. A worn, corroded, or incorrectly drilled orifice causes poor flame quality, sooting, delayed ignition, and reduced heat output — so using the factory-correct drill size is essential.
Genuine Goodman orifices are precision-drilled to the exact size Goodman engineered for this furnace's BTU input and manifold pressure. Generic or re-drilled orifices risk over- or under-firing, which wastes fuel and can create dangerous combustion conditions. For any gas-metering part, OEM is strongly recommended.
Moderate (3/5). Requires shutting off the gas supply, removing the manifold or burner, and threading in the new orifice. A combustion analysis is recommended after replacement. Gas work should be performed by a qualified HVAC technician.
