Gas surface burner ignites but flame is uneven, yellow, or noisy.

Safety first: Turn off burner and allow it to cool before cleaning.

• Clean burner: Remove burner cap and head. Clean all ports and surfaces with warm soapy water and a soft brush. Dry thoroughly.
• Check gas type: Confirm the range is configured for your gas type (natural gas vs LP). If recently converted, verify correct orifices were installed.
• Adjust air shutter (if accessible): Some burners have adjustable air shutters near the orifice. A technician can adjust these to correct yellow or lifting flames.
• Service regulator: If flames are abnormal on all burners, the regulator or supply pressure may be incorrect and should be checked by a professional.
