The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) for the GDT090-4A gas furnace and matching Goodman/Amana burners. This precision-drilled brass orifice meters the exact gas flow into each burner for clean, efficient combustion. A worn, corroded, or incorrectly sized orifice causes poor flame, sooting, delayed ignition, and reduced heating output.
Orifice drill size directly controls the BTU input and air/fuel ratio, so an OEM orifice guarantees the correct bore for safe, code-compliant firing. Generic or mis-sized spuds risk over- or under-firing the furnace, producing carbon monoxide or nuisance lockouts. For a combustion component, always match the OEM specification.
Intermediate (3/5) — Requires shutting off the gas supply, removing the manifold or burner, and threading the orifice to spec. Because it involves the gas train, a licensed technician and post-repair combustion check are recommended.
