The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud for AMH80903BNAA and compatible Goodman/Amana gas furnaces. The orifice threads into the gas manifold and meters the precise volume of natural gas delivered to each in-shot burner, setting the furnace's BTU input. Correct orifice sizing is critical for safe, efficient combustion and proper flame appearance.
Orifices are a safety-critical, precision-drilled part — the bore diameter directly controls gas flow. We stock only genuine OEM spuds because even a few thousandths of variance changes BTU input and can cause sooting, delayed ignition, or overfiring. Do not substitute a generic here.
Moderate (3/5). Shut off gas and power, then unthread the old orifice from the manifold and install the replacement with proper torque and pipe sealant per the manual. Confirm you are using the natural-gas (not LP) orifice for your altitude. A gas-appliance check is recommended after service. Approx. 20–30 minutes.
Compatible with Goodman and Amana furnaces. Verify fuel type and BTU rating before ordering.
