The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud for Amana/Goodman AMH81005CNBD gas furnaces. This precision-drilled orifice meters the exact volume of natural gas delivered into each in-shot burner, setting the furnace's firing rate and ensuring a clean, correctly proportioned air-fuel mixture.
Because orifice bore size directly controls BTU input, using the wrong or damaged orifice can lead to over-firing, sooting, poor efficiency, or delayed ignition. Replacing a worn or incorrectly sized orifice restores rated performance.
This genuine OEM Goodman orifice is drilled to the manufacturer's exact bore specification for your model and altitude rating. Generic orifices may have inconsistent bore sizing, throwing off the BTU input and combustion balance. OEM guarantees correct gas metering out of the box.
Moderate (3/5). Threads into the manifold in place of the existing spud; requires shutting off gas, removing the burner if needed, and verifying no leaks with a leak test. Gas orifice replacement should be performed by a licensed HVAC technician. Confirm the correct bore for natural gas and local altitude.
