The Goodman B2589343 Natural Gas Burner Orifice is a genuine OEM spud that meters fuel into the burner tube on GMNT080-4 gas furnaces and compatible Goodman/Amana models. The orifice is factory-drilled to deliver the exact BTU input the furnace is rated for. A worn, damaged, or incorrectly sized orifice causes poor flame, sooting, delayed ignition, or improper heat output — the OEM part guarantees clean, correctly metered combustion.

Type: Threaded burner orifice / spud
Fits: Goodman GMNT080-4 and select Goodman/Amana furnaces

OEM vs. Generic

Orifice sizing is critical to safe combustion. The OEM B2589343 is precision-drilled to Goodman's specification; generic or hand-drilled orifices risk over- or under-firing the furnace. Always match the OEM spud for natural gas service.

Install Difficulty

Moderate (3/5) — Shut off gas and power. Access the burner assembly, unthread the old orifice from the manifold, and install the new one with proper thread sealant rated for gas. Leak-test all connections before returning to service. Recommended for experienced DIYers or a licensed technician. 20–40 minutes.
