Gas cooktop burner flame is yellow, noisy, or lifting off the burner

Safety first: Turn off the burner and allow it to cool. Gas adjustments should be performed by qualified personnel.

• Check cap placement: Ensure the burner cap is correctly seated and matches the burner base size.
• Clean air inlets: Inspect the area under the burner head for dust, grease, or debris blocking air inlets. Clean with a brush and vacuum.
• Verify gas type: Confirm that the appliance is configured for your gas type (natural gas vs LPG) and that the correct injectors and regulator are installed.
• Professional adjustment: If flames remain yellow or noisy, a technician should check gas pressure and adjust or replace injectors and regulator as needed.
