The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud for Amana AMES960804CNAA 96% AFUE gas furnaces. The orifice meters the precise volume of natural gas delivered to each burner, setting the flame size and combustion mix for safe, efficient, in-spec firing. A worn, corroded, or incorrectly sized orifice causes poor flames, sooting, delayed ignition, and reduced efficiency.
Orifice bore diameter directly controls the furnace's input rate. The factory Goodman orifice is drilled to the exact size specified on the AMES960804 rating plate for natural gas. Generic or mis-drilled orifices can over- or under-fire the furnace, creating a carbon-monoxide or efficiency hazard. For a combustion component, OEM is strongly recommended.
Moderate (3/5). Requires shutting off the gas supply, removing the burner assembly or manifold, and threading the new orifice to the correct torque. Best performed by a licensed HVAC technician who can verify manifold pressure and confirm the flame after replacement.
Note: This is a natural-gas orifice. Do not use on LP/propane furnaces — LP requires a smaller orifice from the correct conversion kit.
