The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud engineered as an exact-fit replacement for Amana/Goodman AMH950904CXAC furnaces. The orifice meters the precise volume of natural gas delivered to each burner, ensuring clean, efficient combustion and the correct BTU input for the AMH950904 heat exchanger.
The genuine 10716003 has a factory-drilled bore sized for this furnace's manifold pressure and altitude rating. Using a generic or wrong-drill orifice alters the gas-to-air ratio, causing sooting, delayed ignition, flame roll-out, or an over/under-fired burner. OEM guarantees the correct orifice diameter and thread for safe operation.
Moderate — Requires removing the burner assembly and threading the new orifice into the manifold. Because it directly affects combustion and safety, professional HVAC installation is strongly recommended. Shut off gas and power, and verify manifold pressure after replacement.
