Goodman B2589343 Natural Gas Burner Orifice

The Goodman B2589343 is a genuine OEM natural gas burner orifice (spud) engineered as a direct-fit replacement for the GMP075-4 gas furnace. This precision-drilled brass orifice meters the exact volume of natural gas delivered to each burner, ensuring a clean, efficient, properly proportioned flame. An orifice that is clogged with debris, corroded, or incorrectly sized causes poor combustion, sooting, delayed ignition, or a lazy yellow flame. Replacing a worn or fouled orifice with the correct OEM spud restores safe, efficient heating performance.

OEM vs. Generic

The genuine Goodman OEM orifice is drilled to the factory-specified diameter for the GMP075-4's rated BTU input, guaranteeing correct gas flow and safe combustion. Generic orifices can differ in bore size and thread pitch, risking over- or under-firing. Because orifice sizing is a combustion-safety matter, OEM is strongly recommended.

Installation Difficulty

Easy to Moderate. Shut off gas and power, remove the burner assembly, and thread out the old orifice with a properly sized wrench. Verify the replacement matches the original marking before installing. This is a combustion component — if you are not comfortable working on gas systems, have a licensed HVAC technician perform the swap.

Always shut off electrical power and gas supply before servicing your furnace.
