The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) for the WGFD28115V5CXAA gas furnace and compatible Goodman/Amana units. This precision-drilled brass orifice meters the exact volume of natural gas into each burner, ensuring a clean, blue, properly proportioned flame. A worn, corroded, or incorrectly sized orifice causes poor combustion, sooting, delayed ignition, and reduced efficiency — replacing it restores the furnace to factory firing rate.
Orifice drill size is matched to your furnace's rated input and manifold pressure. The OEM 10716003 guarantees the correct bore for safe, efficient combustion. Generic orifices with an incorrect drill size can over- or under-fire the furnace, creating carbon monoxide risk. Use the OEM part.
Moderate. Requires removing the burner assembly and threading the new orifice into the manifold. Shut off gas and power first, and verify a clean flame and correct manifold pressure after install. If you are unsure, use a licensed technician.
