The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud for the AMH80803BNBD gas furnace and compatible Goodman/Amana models. The orifice is the precision-drilled brass fitting that meters the exact volume of natural gas delivered to each in-shot burner. Its drill size determines the furnace's firing rate and BTU output, so an incorrect or damaged orifice causes under-firing, over-firing, or poor flame quality.
This OEM Goodman orifice is drilled to the exact diameter matched to your furnace's manifold pressure and BTU rating. Generic or mis-sized orifices change the air-fuel ratio, which can cause sooting, incomplete combustion, or carbon monoxide production. Gas metering is safety-critical — always use the OEM orifice specified for your model and altitude.
Moderate. The orifice threads into the gas manifold and aligns with each burner venturi. Shut off gas and power, use a proper wrench to avoid burring the brass, and leak-check every joint with soap solution after reassembly. Because this involves live gas piping, hire a licensed HVAC technician if you are not confident performing a leak test.
