The 10716003 is a genuine OEM Goodman natural-gas burner orifice (spud) for the AMH81405DXCC gas furnace and matching Goodman/Amana models. This precision-drilled brass fitting threads into the manifold and meters the exact gas flow into each in-shot burner. Correct orifice sizing is what delivers the proper input BTU rating, a clean blue flame, and safe, efficient combustion.
Orifice bore diameter is the single variable that sets your furnace's firing rate. The genuine Goodman 10716003 is drilled to the factory-specified size for correct BTU input at standard manifold pressure. Generic or mis-sized orifices can over- or under-fire the furnace, causing sooting, short cycling, or unsafe operation. OEM is essential here.
Moderate (2/5). Threads into the gas manifold and requires a nut driver or socket; do not over-torque the soft brass. Shut off gas and power, replace the spud, then leak-check all joints and confirm a clean flame at startup. Recommended for a qualified technician.
