The Goodman 10716005 natural gas orifice is a genuine OEM burner spud for the VDS80603ANAA gas furnace. This precision-drilled brass orifice meters the exact volume of natural gas delivered to each burner, ensuring a clean, stable flame and the rated BTU input. A worn, corroded, or incorrectly sized orifice causes lazy yellow flames, sooting, delayed ignition, and reduced efficiency — restoring the factory orifice returns combustion to spec.
The OEM 10716005 is drilled to the precise orifice size Goodman specified for this furnace's manifold pressure and BTU rating. Generic orifices with even a slightly larger or smaller bore change the gas flow, risking over-firing (heat exchanger damage) or under-firing (poor heating, condensation). For combustion parts, factory sizing is non-negotiable.
Shut off the gas and disconnect power. The orifice threads into the manifold; use a properly sized socket or wrench to avoid rounding the hex. Verify this is natural gas (not LP) before installing. After replacement, leak-test all connections with soap solution and confirm a crisp blue flame. Manifold work is best performed by an experienced or licensed technician.
