The Goodman 10716005 Natural Gas Orifice (burner spud) is a genuine OEM metering component for the AMVC80804CNBC gas furnace and compatible Goodman/Amana models. The orifice threads into the manifold and meters the precise volume of natural gas fed to each in-shot burner. Its bore diameter directly sets the furnace's BTU input, so a damaged, corroded, or incorrectly drilled orifice causes lazy yellow flames, sooting, delayed ignition, or under/over-firing.
The OEM 10716005 is drilled to the exact orifice size Goodman specifies for this model's rated input and gas pressure. A generic or wrong-size orifice changes the firing rate and can create dangerous incomplete combustion. Never substitute a natural-gas orifice for an LP orifice — the bore sizes are not interchangeable.
Easy — Shut off gas and power, unthread the old orifice from the manifold with a nut driver, and thread in the exact-match replacement. Leak-check with soap solution and verify a clean blue flame after restart. Gas work should be done by a qualified HVAC technician.
