The Goodman 10716005 is a genuine OEM natural-gas burner orifice (spud) for the ACEC960403BNAB furnace. The orifice threads into the manifold and meters the precise volume of natural gas delivered to each burner. Its drill size is matched to the furnace's BTU rating and gas type, ensuring a clean blue flame, correct combustion, and rated efficiency. A damaged, corroded, or incorrectly sized orifice produces sooting, lifting flames, or under-firing.
Orifice sizing is critical and safety-related. The genuine Goodman 10716005 is drilled to the exact specification for this furnace's input rating. Generic or mis-drilled orifices change the firing rate and can create dangerous combustion conditions. We strongly recommend OEM, and never substitute an LP orifice on a natural-gas appliance.
Moderate (3/5). Turn off the gas and power, remove the burner assembly, and unthread the orifice from the manifold with a properly sized socket or wrench. Reinstall snugly without over-torquing. A combustion analysis after replacement is recommended.
