The Goodman 10716005 Natural Gas Orifice (burner spud) is the genuine OEM metering jet for the AMVC80805CXBC gas furnace. Threaded into the manifold, each orifice meters natural gas into an in-shot burner at the precise rate needed to hit the furnace's rated BTU input. A damaged, corroded, or wrong-size orifice throws off the fuel/air mixture and causes yellow flames, sooting, poor efficiency, or nuisance lockouts.
OEM 10716005 orifices are drilled to Goodman's exact metering spec for this model's altitude and BTU rating. Generic or mis-drilled spuds change gas flow and can create unsafe combustion. Because orifice sizing is tied directly to input and clearance-to-combustibles ratings, the OEM part is strongly recommended.
Rated Moderate (3/5). Requires shutting off gas and power, accessing the manifold, and swapping the spud with the correct wrench without cross-threading. Replace all orifices as a set and perform a leak and combustion check afterward. Gas-side service should be verified by a licensed HVAC technician.
