The Goodman 10716003 is the genuine OEM natural-gas burner orifice (spud) for GMH950905CXAB 95% AFUE gas furnaces. This precision-drilled brass jet threads into the manifold and meters the exact gas flow into each burner, setting the firing rate and flame quality of the furnace. A worn, corroded, or incorrectly drilled orifice throws off the air-fuel mix, causing sooting, poor flame, delayed ignition, or reduced heat output — so exact bore size matters.
The genuine OEM orifice carries the exact bore diameter Goodman specified for this furnace's input rating and manifold pressure. A generic or mismatched orifice can over- or under-fire the burner, risking incomplete combustion and elevated CO. For any gas-metering part, use the correct OEM spud — one orifice per burner, all matched.
Moderate (3/5). Shut off gas and power. Remove the burner assembly or manifold as needed, unthread the old orifice with the correct wrench, thread in the replacement snugly (do not overtighten brass), reassemble, then leak-check the connections with soap solution and verify a clean blue flame.
