The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) designed as a direct-fit replacement for the AMS80453ANAA gas furnace and compatible Goodman/Amana models. The orifice meters natural gas into each in-shot burner, establishing the furnace's rated BTU input for safe, efficient heating. Replace corroded, clogged, or incorrectly sized orifices to restore a clean blue flame.
OEM natural gas orifices are precision-drilled to the factory specification so gas input matches the rating plate. Generic or field-modified orifices risk over- or under-firing the burners, leading to sooting, short cycling, or heat-exchanger stress. If converting between natural gas and LP, always use the fuel-specific factory orifice—never enlarge an existing one.
Moderate (2/5). Shut off the gas supply and power, back out the old orifice with a deep socket, and thread in the new 10716003 snugly without over-tightening. Confirm the orifice matches your fuel type and verify manifold pressure. A licensed technician should check combustion after installation.
