The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) engineered for the GCH90704CXAB gas furnace and related Goodman/Amana models. This precision-drilled brass orifice meters the exact volume of natural gas delivered to each burner, establishing the correct air-fuel mixture for clean, efficient, and safe combustion. Even a slightly incorrect bore diameter can cause sooting, delayed ignition, poor flame quality, or elevated carbon monoxide — which is why the factory-machined orifice matters.
The OEM 10716003 is drilled to Goodman's certified orifice size for your furnace's rated input. Generic orifices frequently vary in bore diameter, throwing off the BTU rating and combustion balance. For a component that directly affects combustion safety and efficiency, OEM is strongly recommended.
Moderate — Requires shutting off the gas supply, removing the manifold or burner, and threading the orifice to spec without cross-threading. HVAC professional installation is recommended for gas-side work.
