The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud engineered for the AMH80703AXCA 80% AFUE gas furnace and compatible Goodman/Amana models. The orifice meters the precise flow of natural gas into each burner, ensuring a clean, correctly-sized flame, proper input BTU rating, and safe, efficient combustion. Using the factory-specified drill size is critical to avoid over- or under-firing.
The genuine OEM 10716003 is drilled to the exact orifice diameter matched to this furnace's manifold pressure and BTU input. An incorrect generic orifice changes the gas flow, causing sooting, poor efficiency, or unsafe firing. For a fuel-metering component, OEM sizing is essential.
Easy–Moderate (2/5) — Threads into the manifold; requires a wrench and care not to cross-thread. Shut off gas and power, and always verify manifold pressure and flame appearance after replacement.
