The Goodman 10716003 Natural Gas Burner Orifice is a genuine OEM fuel-metering component for GCH950905DXAC gas furnaces and compatible Goodman/Amana equipment. Also called a spud, this precision-drilled brass orifice meters the exact volume of natural gas delivered to each burner for clean, efficient combustion and reliable ignition. A damaged, corroded, or incorrectly sized orifice causes poor flame, sooting, delayed ignition, or lockouts.
The OEM 10716003 is drilled to the precise orifice size specified for this furnace's BTU rating and manifold pressure. Even a small deviation in generic orifices changes the fuel-air ratio and can create unsafe or inefficient combustion. Always match OEM sizing — never drill or substitute by guess.
Rated Moderate (3/5). Requires shutting off the gas, removing the manifold or burner assembly, and correctly threading the orifice. Best for experienced DIYers; if you're not comfortable working with the gas manifold, hire a licensed HVAC technician.
