The Goodman 10716003 is a genuine OEM natural-gas burner orifice (spud) for the AMVC951155DXAA two-stage variable-speed furnace and compatible Goodman/Amana models. The orifice is a precision-drilled brass fitting that threads into the manifold and meters the exact volume of natural gas delivered to each burner. Because furnace input rating and flame quality depend directly on the orifice bore, using the correct factory-drilled part is essential for clean, efficient, safe combustion.
The drilled bore diameter sets the firing rate to the furnace's rated BTU input. An incorrectly sized generic orifice over- or under-fires the burner, causing sooting, delayed ignition, or reduced efficiency. For a combustion component, genuine OEM sizing is non-negotiable.
Shut off gas and power, remove the manifold or burner as needed, unthread the old orifice, and install the replacement to spec. Verify manifold pressure and flame after service. Best performed by a qualified technician — 15-25 minutes.
