The Goodman 10716005 is a genuine OEM natural gas burner orifice (spud) for the ACES800403ANAA furnace and compatible models. The orifice is the precision-drilled brass jet that meters the exact volume of natural gas into each burner, ensuring a clean, efficient, and safe flame. A clogged, corroded, or incorrectly sized orifice causes poor combustion, sooting, lazy or lifting flames, and reduced heat output. Using the factory orifice guarantees the correct firing rate for your model.
The OEM 10716005 is drilled to Goodman's exact orifice number for this furnace's BTU input and elevation rating — critical for safe combustion. Generic or mis-sized orifices can over- or under-fire the burner, producing carbon monoxide or a tripped limit. With a gas-metering part, OEM is not optional for safety.
Moderate — Shut off the gas supply, remove the manifold/burner assembly, unscrew the orifice, and install the correct replacement with proper thread sealant rated for gas. Allow 30–60 minutes. Gas work should be performed by a licensed technician, and a combustion check is recommended afterward.
