The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) designed for the WFM18115S5CXCC furnace and compatible Goodman and Amana gas furnaces. The orifice is a precision-drilled brass fitting that meters the exact volume of natural gas delivered to each burner. Correct orifice sizing is essential for a clean, efficient flame, proper BTU input, and safe combustion — an incorrect bore can cause sooting, delayed ignition, or a flame that overheats the heat exchanger.
This genuine OEM orifice is drilled to the precise diameter specified for your furnace's rated input at your altitude and gas type. Generic orifices vary in bore tolerance, which directly affects flame quality and safety. For combustion components, matching the OEM spec is the reliable choice.
Easy to Moderate (2/5). Threads into the manifold in place of the existing orifice using a deep socket or wrench. Shut off gas and power first, and always leak-test the connection with soapy water after reassembly. High-altitude conversions may require a different orifice size — verify before ordering.
