The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud that meters the precise volume of natural gas delivered to each burner in Goodman ACEC961005CNAA furnaces. A correctly sized orifice is essential for a clean blue flame, complete combustion, and the furnace's rated input rate — a worn, drilled, or mismatched orifice causes sooting, lazy flames, and efficiency loss.
Orifice bore diameter directly controls the gas-air mixture. Generic or hand-drilled orifices rarely match the factory bore tolerance, risking over- or under-firing. This OEM orifice is machined to Goodman's exact specification for safe input rate and clean ignition every cycle.
Moderate (3/5). Requires shutting off gas and power, removing the burner assembly, and threading the orifice to spec with a proper wrench. Leak-check after reassembly. If you are not comfortable working on gas piping, hire a licensed HVAC technician.
