The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud for the Goodman GMV951155DXBB 96% AFUE two-stage variable-speed gas furnace. This precision-drilled orifice meters the exact volume of natural gas into each burner, ensuring a clean, efficient flame, correct BTU input, and proper flame-sensor rectification. A worn, corroded, or incorrectly sized orifice can cause sooting, delayed ignition, or lockout faults.
Genuine Goodman orifices are drilled to the precise factory diameter matched to the GMV95 BTU rating and manifold pressure. Generic or mis-sized orifices alter the gas-air ratio, risking incomplete combustion, elevated CO, or nuisance lockouts. For a fuel-metering part, OEM sizing is non-negotiable.
Moderate. About 20–30 minutes with a nut driver or wrench. Shut off gas and power, remove the burner assembly, unthread the old orifice from the manifold, and install the correct replacement. Because this affects combustion, a licensed HVAC technician should verify manifold pressure and flame quality with a combustion analyzer afterward.
