Possible Causes

Incorrect orifice for gas type (NG vs LP), Blocked burner air shutter, Low gas pressure, Debris in burner ports

How to Fix / Troubleshooting

Safety first: Turn off the burner and allow components to cool. If you suspect a gas supply issue, contact a licensed gas technician.

  • Clean burner: Remove burner cap and head. Clean all ports thoroughly with a soft brush and toothpick. Ensure the burner sits correctly when reinstalled.
  • Check gas type conversion: Verify the range or cooktop is configured for your gas type (natural gas or LP). If recently converted, confirm the correct Wolf conversion kit and orifices were used.
  • Inspect air shutters: Some models have adjustable air shutters on the burner tubes. With a qualified technician, adjust the shutter to achieve a blue, stable flame.
  • Gas pressure check: If flames remain yellow, have a licensed gas fitter measure and adjust supply pressure and regulator settings.
