The genuine OEM Goodman 10716005 Natural Gas Orifice is a direct-fit replacement for AMVC80805DNCA variable-speed gas furnaces. Also called a burner spud, this precision-drilled brass fitting threads into the manifold and meters the exact volume of natural gas delivered to each in-shot burner. Correct orifice sizing is essential for the proper gas/air ratio, clean blue flame, rated BTU output, and safe combustion.
The orifice bore diameter directly controls firing rate — a difference of a few thousandths of an inch changes the flame and BTU output. The OEM 10716005 is drilled to Goodman/Amana's exact specification for this furnace, ensuring correct input and passing combustion-analysis checks. Generic or mis-drilled orifices risk over-firing, sooting, or incomplete combustion.
Moderate (3/5). Shut off gas and power, then unthread the old orifice from the manifold and thread in the replacement without cross-threading or over-tightening. Combustion-critical work: a licensed HVAC technician should verify manifold gas pressure and flame quality afterward.
