The OEM Goodman 10716003 is a precision-drilled natural-gas burner orifice (spud) for the Goodman/Amana AMH80903BXAA gas furnace and compatible 80% AFUE models. Threaded into the manifold, the orifice meters the exact volume of natural gas delivered to each burner, ensuring correct BTU input, clean combustion, and proper flame characteristics.
Orifice bore diameter directly controls firing rate. The OEM 10716003 is drilled to Goodman's exact specification, so your furnace fires at its rated input for safe, efficient heat. Undersized or oversized generic orifices can cause sooting, delayed ignition, or overfiring. Always match the orifice to fuel type and altitude — OEM removes the guesswork.
Moderate (3/5). Removal requires shutting off gas and power, disconnecting the manifold, and backing out the old spud with the correct nut driver. Because this is a gas-carrying component, a leak check with soap solution is mandatory after reassembly. A licensed HVAC technician is recommended.
