The Goodman 10716005 Natural Gas Burner Orifice is a genuine OEM metering spud designed for the AMH80403ANBC gas furnace and related Goodman/Amana models. Each orifice is precision-drilled to a specific diameter that controls the exact volume of natural gas delivered to the burner, setting the furnace's rated BTU input and ensuring clean, efficient combustion.
An incorrect or worn orifice throws off the air-fuel ratio, leading to sooting, delayed ignition, yellow flames, or under/over-firing. Replacing a damaged spud with the factory-spec part restores proper burner performance.
Orifice sizing is unforgiving — the genuine OEM 10716005 is bored to Goodman's exact specification for this furnace's manifold pressure and BTU rating. Generic orifices may vary by a drill size, quietly shifting the firing rate and combustion quality. For a combustion component, the OEM part protects both efficiency and safety.
Easy–Moderate (2/5) — Threads into the manifold after the burner is removed. Shut off gas and power first, and always leak-test the connection with soap solution after reassembly. Confirm proper flame appearance on restart.
