The Goodman 10716003 natural gas orifice (spud) is a factory-original metering component for the GMV950905DXBB 95% AFUE variable-speed furnace. Threaded into the burner manifold, its precision-drilled bore delivers the exact fuel volume each burner needs for a clean, stable blue flame. A worn, corroded, or incorrectly sized orifice can cause yellow flames, sooting, delayed ignition, or reduced heat output.
The OEM Goodman orifice is drilled to the manufacturer's certified bore diameter, ensuring correct gas input rate and safe combustion for your specific model. A generic orifice can serve as a lower-cost replacement but must exactly match the OEM drill size — always confirm the stamped number before installing. For gas components, OEM is strongly recommended.
Moderate (2/5). Shut off gas and power, remove the burner assembly, and unthread the orifice with a nut driver. Because this is a gas-carrying part, verify for leaks with soap solution after reassembly.
Gas work should be performed by a qualified technician where required by local code. Always shut off gas supply before servicing.
