Goodman B4089343 #43 Burner Orifice

The Goodman B4089343 is a genuine OEM natural gas burner orifice (spud) drilled to a #43 orifice size, engineered as a direct-fit replacement for the GMPE075-3 gas furnace and other compatible Goodman and Amana models. The orifice meters the precise volume of gas delivered to each burner, ensuring a clean, efficient flame, correct BTU input, and safe combustion. A clogged, corroded, or incorrectly sized orifice causes soot, delayed ignition, and poor heating performance — replacing with the exact OEM part restores factory operation.

Specifications

  • Orifice size: #43 drill
  • Fuel type: Natural gas
  • Material: Machined brass
  • Thread: OEM standard burner spud thread
  • Fits: Goodman GMPE075-3 gas furnace
  • OEM part number: B4089343

OEM vs. Generic

Genuine OEM orifices are machined and gauged to Goodman's exact drill-size tolerance, which directly governs gas input and flame quality. Generic or re-drilled orifices can vary in bore diameter, risking over- or under-firing. For a heating appliance, we strongly recommend the OEM B4089343 for safety and correct BTU output.

Installation Difficulty

Moderate — requires shutting off gas, removing the burner assembly, and swapping the spud. Should be performed by a qualified HVAC technician; always leak-check after installation.
