The Goodman 10716003 Natural Gas Orifice is a genuine OEM replacement spud for the GMT090-4 gas furnace. This precision-drilled brass orifice meters the exact amount of natural gas delivered to each burner, ensuring a clean, efficient flame and proper BTU output. A clogged, corroded, or incorrectly sized orifice causes poor combustion, sooting, delayed ignition, or reduced heat output.
Orifice sizing is safety-critical. This OEM Goodman orifice is drilled to the factory-specified diameter for the GMT090-4, guaranteeing correct gas flow and combustion. Generic orifices with even slightly different bore sizes can cause overfiring, incomplete combustion, and dangerous carbon monoxide levels. Always match the exact OEM spec.
Rating: Moderate (Professional Recommended). Replacement involves shutting off the gas supply, removing the burner assembly or manifold, and threading in the new orifice with correct torque and leak-testing. Because it involves the gas train, a licensed technician should verify sizing and check for leaks after installation.
Keep your GMT090-4 burning clean and efficient with the genuine Goodman 10716003 orifice.
