The Goodman 10716003 is a factory-drilled natural gas burner orifice (spud) engineered for the GCH91155DXAB two-stage gas furnace and other compatible Goodman/Amana 96% AFUE models. The orifice threads into the manifold and meters the precise volume of natural gas delivered to each burner, setting the furnace's rated BTU input. A worn, corroded, or incorrectly sized orifice causes poor flame quality, delayed ignition, sooting, or short cycling — installing the correct OEM spud restores clean, efficient combustion.
Generic orifices are frequently drilled to a nominal size that does not match Goodman's factory calibration for this cabinet, leading to over- or under-firing. This genuine OEM 10716003 is drilled to the exact specification your furnace was certified with, ensuring correct input rate, safe combustion, and warranty compliance. If you are converting fuel types, always match the orifice to the gas supply.
Moderate — requires shutting off gas, removing the manifold or burner assembly, and a leak check with soap solution after reassembly. This is a gas-carrying component; if you are not comfortable working with gas connections, have a licensed HVAC technician perform the replacement.
