La Cornue Range No Ignition
La Cornue Range No Ignition is a fault our factory-trained technicians diagnose and repair with genuine parts. Below is what it means, the most likely causes, and the steps to try before booking service.
What Igniter Clicking — No Ignition means on your La Cornue Range
Continuous clicking with no flame is a classic ignition indicator on La Cornue gas ranges. The spark electrode is firing but the burner will not catch, or the clicking continues even after the burner lights. It usually traces to moisture, a misseated cap, or a sticking ignition switch.
Symptoms to look for
The signs below help confirm you are dealing with this condition rather than a different fault. You may notice just one of them or several together, and they can appear gradually over time or suddenly after a spill, a power event, or recent service.
- Persistent clicking but the burner will not light
- Clicking continues even after a flame appears
- Multiple burners may click together (shared module)
- Often follows cleaning or a spill
Common causes
Several different faults can produce these symptoms. Working through the most likely causes in order helps you separate a quick, inexpensive fix from a problem that needs trained service and the correct La Cornue parts.
- Moisture on the electrode/cap — water shorts the spark after cleaning
- Misseated burner cap — cap out of position disrupts the spark gap
- Sticking ignition switch — switch stays closed, clicking continuously
- Dirty electrode — debris on the spark tip
Troubleshooting steps you can try
Work through these checks in order, with the appliance cool and powered down before you touch any internal part. Stop at any point where you are unsure, or where gas, high heat, or live electrical parts are involved, and hand the remaining diagnosis to a qualified technician.
- Dry the burner cap and electrode thoroughly if you recently cleaned the cooktop.
- Reseat the burner cap squarely in position.
- Clean any debris from around the spark electrode.
- If clicking continues with the knobs off, the ignition switch is likely stuck.
When to call a technician
If drying and reseating do not stop the problem, a sticking ignition switch or failing module needs a technician. Continuous sparking should be corrected to avoid switch and electrode wear. You can reach the La Cornue National Service Center on 1-877-522-6768, or find an authorized technician through the manufacturer at lacornueusa.com. La Cornue appliances are hand-built and use proprietary parts, so factory-trained service protects both your warranty and the appliance.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the spark electrode, ignition switch, burner cap, and ignition module. The correct part for your configuration is identified from the model and serial number; on La Cornue appliances these are proprietary components fitted by trained service rather than generic substitutes, which protects both performance and the appliance’s long-term value.
Safety and prevention
To reduce the chance of this returning on your La Cornue Range, keep up with routine care — clean spills before they bake on, follow the manufacturer’s maintenance schedule, and avoid abrasive pads or harsh chemicals on enamel, brass, and finished surfaces. Periodic professional servicing catches wear items early, and addressing small performance changes promptly usually means a simpler repair. When you book service, having the model and serial plate details and a note of exactly what you observed will help the visit go quickly.
