Gas surface burner will not ignite; clicking sound may or may not be present

Safety first: Turn off all burner knobs and ensure the area is well ventilated. Do not use open flames to test for gas leaks.

• Check cap alignment: Remove and reseat the burner cap so it sits flat and centered on the burner base.
• Clean burner: Remove the burner head (if removable) and clean ports with a soft brush and warm soapy water. Ensure all passages are clear and dry thoroughly before reassembly.
• Inspect igniter: The ceramic igniter tip near the burner should be clean and not cracked. Gently clean with a soft brush. Ensure the gap between igniter and burner is similar to other working burners.
• Test spark: Turn the knob to ignite and look for a strong, regular spark at the electrode. If no spark on any burner, the spark module or power supply may be faulty. If only one burner fails, the electrode or its wiring is suspect.
• Replace parts as needed: Replace the burner head, igniter electrode, or spark module with La Cornue‑specified components if cleaning and alignment do not restore ignition.
