The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) for the GKS90904CXAC gas furnace and compatible Goodman/Amana models. Threaded into the manifold, this precision-drilled orifice meters the exact volume of natural gas delivered to each burner, ensuring a clean, correctly-sized flame and rated BTU output.
Orifice sizing is critical — the drill number determines your furnace's gas input and combustion safety. A genuine Goodman orifice guarantees the factory-specified bore for your altitude and fuel type. Incorrectly sized aftermarket orifices can cause sooting, delayed ignition, or dangerous over-firing. Always match OEM specs.
Moderate. Requires shutting off gas and power, removing the burners, and unthreading the old orifice from the manifold. Verify the drill size stamped on the part matches your unit's spec plate. Recommended for experienced DIYers or an HVAC technician.
