The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud precision-drilled for the AMVC80804CXBC 80% AFUE gas furnace. The orifice meters the exact volume of natural gas delivered to each burner, setting the flame characteristics and the furnace's rated input BTU. Using the correct orifice size is critical: an over-sized bore over-fires the burner and can crack the heat exchanger, while an under-sized bore starves the flame and causes incomplete combustion.
OEM vs. Generic: Orifice drill size is not something to guess at. The OEM 10716005 is bored to the manufacturer's specification for this furnace's manifold pressure and burner design. Aftermarket orifices with an approximate size can shift the firing rate outside safe limits. For a combustion component, OEM is the safe and code-correct choice.
Installation difficulty: Moderate (3/5). Shut off gas and power first. The orifice threads into the manifold; replace one at a time to avoid mixing positions, and always leak-check joints with soap solution after reassembly. Confirm the flame is clean and blue on restart. If converting fuel types, use the manufacturer's conversion kit rather than a standalone orifice.
