The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) for the AMH80703AXCC gas furnace and other compatible Goodman and Amana models. Threaded into the manifold ahead of each in-shot burner, the orifice meters the exact gas flow that mixes with combustion air, so its factory-drilled bore directly sets the furnace's BTU input and combustion efficiency. An orifice that is corroded, damaged, or incorrectly sized skews the air-fuel ratio and can cause sooting, lazy flames, or nuisance flame-sensor faults.
The OEM 10716003 is precision-drilled to the specific bore diameter Goodman rates for this furnace's input. A generic orifice with even a slightly different drill size shifts the manifold flow and firing rate out of spec. For safe, on-rate combustion, install the genuine orifice.
Moderate (2/5). Shut off gas and power, remove the manifold, and unthread the old orifice with the correct nut driver. Thread in the new spud snugly without over-torquing, then verify manifold pressure and check the flame after start-up.
