The Goodman 10716003 Natural Gas Burner Orifice is a genuine OEM replacement engineered for the GKS91155DXAC gas furnace and many other Goodman and Amana furnace models in the same series. The orifice (spud) meters the precise flow of natural gas into each burner, delivering a clean, correctly-sized flame for safe, efficient combustion. A worn, corroded, or incorrectly drilled orifice causes lazy yellow flames, sooting, delayed ignition, or nuisance lockouts — this exact-fit part restores factory performance.
Unlike universal generic spuds that require re-drilling and hand-gauging, this factory OEM orifice arrives pre-drilled to Goodman's exact orifice size for your input rating and elevation defaults. That guarantees the correct BTU input and eliminates the guesswork and combustion-safety risk of an under- or over-sized generic. Generic parts are cheaper up front but can void warranty coverage and fail combustion analysis.
Rated Easy for a qualified technician — typically a 10–15 minute swap. Shut off gas and power, remove the burner assembly, unthread the old orifice from the manifold, and thread in the replacement with proper pipe sealant rated for gas. Always verify manifold pressure and perform a combustion/leak check after installation. Gas work should be performed by a licensed HVAC professional in accordance with local code.
