The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud engineered for the Goodman ADVC81155CXAA gas furnace. The orifice meters the precise volume of natural gas delivered to each in-shot burner, setting the furnace's BTU input and flame quality. A clogged, corroded, or incorrectly sized orifice causes weak or oversized flames, sooting, delayed ignition, and efficiency loss — making the correct OEM orifice critical to safe operation.
Genuine OEM Goodman orifices are precision-drilled to the exact bore diameter certified for this furnace's rated input. Using a mismatched generic orifice can over- or under-fire the burners, creating unsafe combustion and CO risk. For a fuel-metering component, always use the OEM-specified orifice.
Rating: Moderate (3/5). Requires shutting off gas, removing the manifold or burner, and threading in the new orifice — about 30 minutes. Because this affects the gas input rate, professional installation is recommended, and combustion should be verified after service.
