Possible Causes

Dirty burner ports, Incorrect injector (jet) size for gas type, Wrong gas type (LPG vs natural gas), Insufficient primary air adjustment

How to Fix / Troubleshooting

Safety: Turn off gas supply before removing burners or injectors. Work in a well-ventilated area.

  • Clean burner: Remove burner cap and head. Clean all ports and surfaces to remove grease and carbon.
  • Check cap seating: Ensure the burner cap sits flat and centered.
  • Verify gas type: Confirm that the cooktop is configured for your gas type (natural gas or LPG). If recently converted, ensure the correct injectors were installed.
  • Air shutter adjustment: Some burners have adjustable air shutters under the cooktop. A qualified technician can adjust these to correct flame characteristics.

Warning: Persistent yellow or lifting flames can produce carbon monoxide. If you cannot correct the flame, stop using the appliance and contact a gas technician.
