The Goodman 10716005 is a factory-original natural gas burner orifice engineered for the Amana AMVC80603BNCA 80% AFUE two-stage variable-speed gas furnace and compatible Goodman/Amana models. The orifice (spud) meters the precise volume of natural gas delivered to each burner, so a worn, drilled-out, or incorrectly sized orifice directly affects flame quality, BTU output, and combustion safety. Installing the correct OEM spud restores the manufacturer-specified fuel rate and blue, stable burner flame.
Generic drill-set orifices require field drilling to size and risk over- or under-firing the furnace. This genuine OEM 10716005 arrives pre-sized to Goodman's specification, guaranteeing correct manifold pressure and clean combustion without guesswork. For a gas-metering component, exact factory sizing is a safety issue — not a place to improvise.
Moderate — Requires shutting off the gas supply, removing the burner assembly, and threading the new orifice to spec. Recommended for HVAC technicians or experienced DIYers. Always leak-check with the gas on before returning the furnace to service.
