The Goodman 10716003 is a genuine OEM natural gas burner orifice for the AMS81155CXAA multi-position gas furnace and compatible AMS8 series models. This brass spud meters the precise gas flow into the in-shot burners, establishing the furnace's rated BTU input and ensuring a stable, efficient flame. Replacing a worn or corroded orifice restores correct firing rate and clean combustion.
Gas orifice bore size is safety-critical and factory-matched to the furnace's certified input rating. Genuine OEM orifices are precision-drilled and verified for correct natural gas flow. Off-spec generic spuds risk over-firing, sooting, or unsafe combustion. For any gas metering part, insist on OEM.
Moderate (3/5). Threads into the manifold and requires leak testing and flame verification. Professional installation by a licensed HVAC technician is strongly recommended for gas components.
