The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) for GDH80403AXAA and compatible Goodman/Amana 80% AFUE gas furnaces. This precision-drilled brass orifice meters the exact volume of natural gas into each in-shot burner, setting the input rate that drives clean, efficient combustion.
Orifice bore size is not something to guess at — even a small deviation changes BTU input, flame character, and combustion safety. A damaged, corroded, or incorrectly sized orifice can cause a lazy yellow flame, sooting, or delayed ignition. Replacing with the factory-spec orifice restores rated input and a crisp blue flame.
OEM vs. Generic: OEM orifices are drilled and gauged to Goodman's exact specification for this furnace's input rating and altitude assumptions. Generic orifices with off-spec bores can over- or under-fire the furnace. For a metered gas component, always match OEM.
Install Difficulty: Easy. Threads into the manifold; back out the old orifice with a nut driver or socket and thread in the new one. About 10–15 minutes per orifice. Shut off gas before servicing and leak-check when done.
