The Goodman 10716003 Natural Gas Burner Orifice is a genuine OEM metering spud designed for the AMVC80704BXAB 80% AFUE variable-speed furnace. Each orifice threads into the manifold and precisely meters the flow of natural gas to a single burner, ensuring the correct BTU input, clean flame, and safe, efficient combustion. Using the factory-drilled orifice size is critical — an incorrect bore can cause sooting, poor flame, delayed ignition, or dangerous over-firing.
OEM vs. Generic: The Goodman OEM orifice is drilled to the exact size specified for this furnace's rated input. Generic orifices are often sold by nominal size only and may vary slightly in bore, threading, or seat, leading to combustion problems. For a component that directly affects safety and efficiency, the OEM spud is the reliable choice.
Install difficulty: Easy to moderate (2/5). Requires removing the manifold or burner assembly and threading the orifice in with a wrench — take care not to enlarge or damage the bore. Shut off gas and power first, and leak-check every joint after reassembly. When in doubt, use a licensed technician.
