The Goodman 10716005 is a genuine OEM natural gas burner orifice (spud) for the AMVC800603BNAA two-stage variable-speed gas furnace. This precision-drilled brass orifice threads into the manifold and meters the exact volume of natural gas delivered to each burner. Correct orifice sizing is essential for a clean, efficient flame and proper BTU output — a worn, corroded, or incorrectly drilled orifice causes sooting, delayed ignition, uneven flame, and reduced efficiency.
This genuine Goodman/Amana OEM orifice is drilled to the precise diameter the AMVC800603BNAA's input rating requires. Because gas metering is directly tied to combustion safety and efficiency, using the exact OEM orifice is critical — an aftermarket spud with the wrong drill size can over- or under-fire the furnace. Always match OEM here.
Recommended for a knowledgeable DIYer or HVAC professional. Shut off gas and power, remove the manifold/burner assembly, unthread the old orifice, install the new 10716005, and reassemble. A gas leak check and flame/combustion verification after install are strongly advised.
