OEM vs. Generic

The OEM Goodman B2589343 is drilled to the precise orifice size specified for this furnace's BTU input — critical for safe combustion. Because orifice sizing directly affects the fuel-air ratio, we recommend OEM. Never substitute an LP/propane orifice on a natural gas furnace without a proper conversion kit.

Installation Difficulty

Easy to Moderate — Shut off gas and power, remove the manifold or burner as needed, unthread the orifice, and install the replacement with proper torque. Leak-test all connections with soap solution before returning to service.
