The Goodman 10716005 is a genuine OEM natural gas burner orifice (spud) designed for the AMSS921005CNAB gas furnace and compatible Goodman and Amana equipment. This precision-drilled brass orifice meters the exact volume of natural gas delivered to each burner, ensuring a clean, correctly sized flame, efficient combustion, and reliable ignition. An incorrect or worn orifice can cause sooting, delayed ignition, or an improper heat rise, so a factory-matched replacement is essential.
Orifice sizing is drilled to a specific diameter for your furnace's BTU input and manifold pressure. The OEM 10716005 guarantees the correct bore; a generic or mis-sized orifice can over- or under-fire the furnace, wasting fuel and creating a safety hazard. Always match the orifice to the factory spec.
Install difficulty: Moderate (⭐⭐⭐☆☆). Requires shutting off the gas, removing the burner assembly or manifold, and threading in the new orifice with proper torque. Best performed by an HVAC technician who can verify manifold pressure and flame quality afterward.
