The Goodman 10716003 Natural Gas Burner Orifice is a genuine OEM replacement spud engineered specifically for the Goodman GMT090-3A gas furnace and compatible GMT-series models. This precision-drilled brass orifice meters the exact volume of natural gas into each burner, ensuring a clean, efficient flame and the correct BTU input rating your furnace was designed for. A worn, corroded, or incorrectly sized orifice causes lazy yellow flames, sooting, delayed ignition, and CO risk — replacing it restores safe, reliable heating.
The OEM Goodman orifice is drilled to the factory-specified diameter for your altitude and BTU rating, guaranteeing correct gas metering and combustion. Generic or universal spuds may vary in bore size, risking over- or under-firing. For a safety-critical gas component, OEM is strongly recommended.
Easy (1/5) — Threads into the burner manifold with a wrench. Always shut off gas and power before service, and verify flame quality afterward. If you are not comfortable working with gas, hire a licensed HVAC technician.
