The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud for AMVC80805DXBD gas furnaces. This small brass orifice threads into the manifold and precisely meters the volume of natural gas delivered to each in-shot burner. The drill size is matched to the furnace's rated BTU input and manifold pressure — get it wrong and you get over- or under-firing, sooting, or a lazy yellow flame. Replacing a damaged, cross-threaded, or partially blocked orifice restores the correct gas-air ratio and clean blue combustion.
Aftermarket orifices are frequently drilled a size or two off, which shifts BTU output and can create dangerous combustion. This OEM Goodman orifice is factory-drilled to the exact specification for this model, so input, flame quality, and temperature rise stay on target. For natural-gas-to-LP conversions, use the correct LP orifice instead.
Moderate. Shut off the gas and power, remove the manifold or back out the orifice with a nut driver, and install the replacement — do not over-tighten brass. Always leak-test the joint with soap solution and confirm the flame after startup.
