The genuine Goodman 10716005 natural gas burner orifice (spud) is a factory OEM metering component for the AMVC960603BNBA modulating gas furnace and compatible Goodman/Amana models. This precision-drilled brass orifice threads into the manifold and meters the exact volume of natural gas delivered to each burner, setting the furnace's BTU input and ensuring clean, efficient combustion. An incorrect or worn orifice causes improper flame, sooting, delayed ignition, or under/over-firing.
The OEM Goodman orifice is drilled to the precise diameter specified for this furnace's manifold pressure and BTU rating. Generic or field-drilled orifices risk incorrect gas flow, which affects safety, efficiency, and heat-exchanger life. For proper firing rate, use the OEM part.
Moderate (3/5) — requires removing the burner assembly and a nut driver to thread the orifice into the manifold. Shut off the gas supply and power, and verify manifold pressure with a manometer after replacement. Professional service recommended.
