Gas burner will not ignite on a Montpellier gas hob or gas section of a dual-fuel range.

Safety first: Turn all burner knobs to OFF. Do not continue sparking if you smell gas. Ventilate the room and avoid open flames.

• Check gas supply: Ensure the gas isolation valve is open and other gas appliances work. If no gas anywhere, contact your gas supplier.
• Clean burner parts: Remove the burner cap and head. Clean ports with a soft brush or wooden toothpick. Do not enlarge holes.
• Dry components: If the hob was recently cleaned, moisture may prevent ignition. Dry the burner, cap, and electrode thoroughly.
• Check spark: Turn the knob to ignite and look for a strong blue spark at the electrode. If no spark on any burner, the ignition module or power supply may be faulty.
• Replace faulty parts: If only one burner fails to spark, replace that burner’s ignition electrode. If none spark, have a technician test and replace the ignition module.
