The Goodman 10716005 Natural Gas Orifice is the genuine OEM burner spud that meters the precise volume of natural gas delivered to each in-shot burner in the AMS80804BXAD furnace. The orifice's drilled bore sets the BTU input and the air-fuel mixture; even a slight change in bore size shifts the flame from a clean blue to a lazy yellow, causing sooting, incomplete combustion, and carbon monoxide risk. A damaged, corroded, or mis-drilled orifice should always be replaced with the correct factory part.
The OEM 10716005 is drilled to Goodman's exact orifice size for this furnace's manifold pressure and altitude spec. Generic orifices may carry a different drill number, over- or under-firing the burner. Using the factory OEM orifice guarantees the rated BTU input and safe combustion. Note: this is a natural-gas orifice — do not use it for LP conversion.
Moderate (2/5). Shut off gas and power, remove the manifold or burner, unthread the old orifice with the correct wrench, and hand-tighten the new one squarely to avoid cross-threading. Verify flame quality and manifold pressure after startup. Gas work — have it verified if unsure.
