The Goodman 10716005 Natural Gas Orifice is the genuine OEM burner spud that meters fuel into the in-shot burners of AMH80804BNBC furnaces. The precisely drilled orifice sets the gas flow rate that, combined with primary air, establishes the correct BTU input and flame characteristics for the furnace. A damaged, corroded, or incorrectly drilled orifice causes lazy yellow flames, sooting, delayed ignition, or improper heating capacity.
Orifice sizing is precision machining — a few thousandths of an inch changes the firing rate and flame quality. Genuine OEM orifices are drilled to Goodman's exact spec for this furnace and gas type. Generic or mis-drilled spuds risk over/under-firing, poor combustion, and dangerous CO output. Always match the orifice to your fuel (NG vs. LP).
Moderate (3/5). Shut off gas and power, then unthread the old orifice from the manifold and install the new one, sealing appropriately. Because this directly controls combustion, we strongly recommend a licensed technician install it and verify manifold pressure, firing rate, and flame quality.
