The Goodman 10716003 Natural Gas Burner Orifice is a factory OEM replacement spud engineered for the AMH81155CXCB gas furnace and other compatible Goodman/Amana models. The orifice meters the precise volume of natural gas into each burner, so a worn, clogged, or incorrectly drilled orifice directly affects flame quality, BTU output, and combustion safety. Installing the correct OEM part restores the manufacturer's rated firing rate.
OEM vs. Generic: The OEM 10716003 is drilled to Goodman's exact specification for this furnace's manifold pressure and firing rate. Generic or mis-sized orifices can over- or under-fire the burner, causing sooting, delayed ignition, or nuisance limit trips. For a combustion component, OEM is strongly recommended.
Install difficulty: Moderate. Requires shutting off gas, removing the burner assembly, and confirming the drill size matches your manifold. Manifold pressure should be verified after replacement. Best performed by a qualified HVAC technician.
