The Goodman 10716005 Natural Gas Orifice (burner spud) is a genuine OEM metering component for Goodman/Amana AMVC80603BXCA furnaces. The orifice threads into the manifold and precisely regulates the volume of gas delivered to each in-shot burner. Its bore diameter is factory-drilled to match the furnace's rated BTU input and natural-gas supply pressure, ensuring a clean blue flame, correct temperature rise, and maximum efficiency.
Orifice sizing is not a place to improvise. The OEM Goodman orifice guarantees the exact bore diameter for safe, complete combustion. An incorrectly sized generic spud will over- or under-fire the furnace, producing soot, carbon monoxide, or short cycling. Match the OEM number and confirm your fuel type (natural gas vs. LP) before installing.
Easy (2/5). Shut off gas and power, remove the burners for access, unscrew the old orifice with a small wrench, and thread in the replacement — do not overtighten. About 20 minutes. Verify flame quality and check for leaks with soapy water after restoring gas.
