Goodman B2589343 Natural Gas Burner Orifice

The Goodman B2589343 is a genuine OEM natural gas burner orifice (spud) for the GMN080-4 gas furnace. This precision-drilled brass fitting threads into the gas manifold and meters the exact volume of natural gas delivered to each burner, setting the furnace's BTU input and flame quality. A damaged, clogged, or incorrectly sized orifice can cause weak or yellow flames, sooting, delayed ignition, or improper heat output. Installing the correct factory orifice restores clean, efficient, spec-rated combustion.

Specifications

Part number: B2589343
Fuel type: Natural gas
Component: Burner orifice / manifold spud
Material: Precision-drilled brass
Fits: Goodman GMN080-4 furnace
Equipment: Gas furnace

OEM vs. Generic

The OEM B2589343 is drilled to Goodman's exact orifice size for the GMN080-4's rated input, guaranteeing correct BTU delivery and safe combustion. A generic orifice risks an incorrect bore diameter — over-firing (overheating, safety trips) or under-firing (poor heat, sooting). Because orifice sizing directly affects combustion safety, we strongly recommend the OEM part.

Installation Difficulty

Moderate (3/5). The swap itself is quick, but it involves the gas manifold: shut off the gas supply, disconnect power, remove the burner/manifold as needed, thread in the correct orifice, and leak-test every joint with soap solution before relighting. If you are not experienced working on gas piping, have a licensed HVAC or gas technician perform this repair.
