The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner component for the GCH91155DXAE gas furnace and compatible Goodman and Amana models. This precision-drilled orifice (spud) meters the exact volume of natural gas delivered to each burner, ensuring a clean, efficient flame and correct BTU input. A worn, corroded, or incorrectly sized orifice causes sooting, poor combustion, and unsafe operation — making the correct OEM part essential.
Orifice sizing is safety-critical. This OEM Goodman orifice is drilled to the precise diameter your furnace's gas valve and manifold pressure require. Generic or mis-drilled orifices alter the gas-to-air ratio and can produce carbon monoxide. Always match OEM specification and never enlarge an orifice.
Moderate (3 of 5). Requires shutting off the gas supply, removing the burner assembly, and torquing the orifice correctly. Combustion should be verified after installation. Because this is a gas component, we strongly recommend installation by a licensed HVAC technician.
