The Goodman 10716005 Natural Gas Orifice is a factory-original burner spud designed for the VMES800403AXAA gas furnace and related Goodman/Amana models. The orifice meters the precise volume of natural gas delivered to each burner, setting the flame size and the furnace's rated BTU input. A correctly drilled orifice is essential for clean combustion, proper heat exchanger temperatures, and safe, efficient operation.
The genuine OEM 10716005 is machined and drilled to Goodman's exact orifice diameter, so BTU input and manifold pressure stay within spec. Generic orifices with slightly off-size bores can cause sooting, delayed ignition, or an over-fired heat exchanger. For a combustion-critical part, insist on the factory spud.
Difficulty: Easy (2/5). Shut off gas and power, remove the burner assembly or access the manifold, unthread the old orifice with a deep socket, and thread the new one in snug — do not over-torque. Confirm manifold pressure with a manometer after install. Roughly 20–30 minutes for a competent DIYer; hire a licensed tech if unsure about gas work.
