Goodman B4089343 #43 Burner Orifice

The B4089343 is a genuine OEM natural gas burner orifice (spud) engineered for the Goodman GMPE100-4 gas furnace and other compatible Goodman/Amana models. Each orifice is precision-drilled to a #43 drill size, metering the exact gas flow needed to deliver rated BTU input and a clean, stable flame. A worn, corroded, or incorrectly sized orifice causes yellow flames, sooting, poor combustion, and lockouts — replacing it restores efficient, safe heating.

Specifications

OEM Part Number: B4089343
Drill Size: #43
Fuel: Natural Gas
Material: Machined brass
Fits: Goodman GMPE100-4 and compatible furnaces
Thread: Standard Goodman burner manifold

OEM vs. Generic

This is a factory-original Goodman orifice, drilled and gauged to OEM tolerances so BTU input matches the furnace rating plate exactly. Aftermarket orifices often vary in bore diameter, which can push firing rate out of spec and trip safety limits. For a component that directly controls combustion, we recommend the genuine OEM part.

Installation Difficulty

Easy (2/5). The orifice threads into the burner manifold and is replaced with a standard wrench in minutes. Always shut off gas and power before service; a licensed technician should verify manifold pressure and flame after installation.
