The Goodman 10716005 Natural Gas Orifice is a genuine OEM burner spud for the AMEH800603BXAB gas furnace. Threaded into the gas manifold, this precision-drilled orifice meters the exact volume of natural gas into each in-shot burner, setting the furnace's firing rate and flame quality. A worn, corroded, or incorrectly-sized orifice throws off the gas/air mixture, causing sooting, lazy yellow flame, or under-firing.
This genuine OEM Goodman orifice is drilled to the precise diameter specified for your furnace's BTU rating. Even a slightly oversized generic bore over-fires the burner and can overheat the heat exchanger. Because orifice sizing is safety-critical, always match the OEM part and drill size — never guess.
Moderate — Requires removing the burner assembly to reach the manifold, then unthreading and replacing the spud with a nut driver or wrench. Plan 30 minutes. Shut off gas and power, and leak-test the manifold connection after reinstalling. If unsure of the correct orifice size, consult a licensed technician.
