The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner component engineered for the AMH80703AXAA gas furnace and compatible Goodman/Amana 80% AFUE models. The orifice (spud) meters the precise flow of natural gas into each burner, ensuring a clean, stable flame and rated BTU output. A worn, corroded, or incorrectly sized orifice causes uneven heating, sooting, delayed ignition, or nuisance lockouts — replacing with the exact factory part restores safe, efficient combustion.
Generic orifices are often drilled to nominal sizes that do not match your furnace's manifold pressure and BTU rating, risking over- or under-firing. This genuine OEM 10716003 is drilled to Goodman's exact specification, guaranteeing correct gas metering and preserving your equipment warranty.
Rating: Moderate (2/5) — Requires shutting off the gas supply and removing the burner assembly. A licensed HVAC technician should verify manifold pressure and flame appearance after installation. Always confirm the orifice size stamped on the part matches your original before firing the furnace.
