The Goodman 10716003 Natural Gas Burner Orifice is a genuine OEM component engineered for the WGFM28070V4BXAB 80,000 BTU gas furnace and compatible Goodman/Amana models. The orifice (spud) threads into the manifold and meters the precise volume of natural gas delivered to each burner, ensuring a clean, efficient blue flame and correct BTU output. A worn, corroded, or incorrectly sized orifice causes lazy flames, sooting, delayed ignition, and reduced heating efficiency — this OEM part restores factory performance.
OEM vs. Generic: The genuine Goodman orifice is drilled to the exact factory bore diameter for your model's rated input. Generic orifices often vary in bore size, risking over- or under-firing, which affects safety and efficiency. For gas-metering components we strongly recommend OEM to guarantee a correct, code-compliant burn.
Install difficulty: Moderate — requires shutting off the gas supply, removing the burner assembly, and swapping the orifice. Always verify orifice sizing and leak-check connections after installation. If you are not comfortable working with gas, hire a licensed HVAC technician.
