The Goodman 10716003 Natural Gas Burner Orifice is a genuine OEM metering spud for the AMS80704BNAA gas furnace and compatible Goodman/Amana models. Threaded into the manifold ahead of each in-shot burner, the orifice regulates the exact quantity of natural gas entering the combustion cell. A worn, plugged, or mismatched orifice throws off the air-fuel ratio and leads to sooting, noisy ignition, or reduced heating output — this factory-spec replacement restores precise metering and a clean, even flame.
This genuine OEM orifice is bored to the exact size Goodman certified for the AMS80704BNAA at its rated natural-gas input. Generic or field-drilled substitutes risk over- or under-firing the furnace, which compromises efficiency and safety. For code-compliant, warranty-safe combustion, use the OEM part matched to your gas type.
Rated Moderate (2/5). Turn off gas and power, remove the burner assembly to reach the manifold, unthread the old orifice, and install the replacement to the proper depth. Leak-check with soap solution and verify flame quality before restoring service. Recommended for a qualified HVAC technician.
Confirm gas type and quantity for your model before ordering — do not substitute an LP orifice on a natural-gas furnace.
