La Cornue Cooktop Clicking
La Cornue Cooktop Clicking 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 Continuous Clicking means on your La Cornue Cooktop
Continuous clicking from a La Cornue cooktop — especially when the burner is already lit or all knobs are off — is an indicator usually caused by moisture or a sticking ignition switch. The constant sparking is harmless briefly but should be stopped to protect the switch and electrode.
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.
- Clicking continues after the flame is established
- Clicking persists with all knobs in the off position
- Often follows cleaning or a boil-over
- May involve one or several burners
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 — water under the caps shorts the spark circuit
- Misseated cap — disrupts the spark gap, prompting re-sparking
- Sticking ignition switch — switch stays partly closed
- Debris on electrode — fouling 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 caps and surrounding area thoroughly.
- Reseat each burner cap squarely.
- Let the cooktop air-dry fully after cleaning.
- If clicking continues with knobs off, suspect a stuck switch.
When to call a technician
If drying does not stop the clicking, a sticking ignition switch usually needs a technician to replace. Persistent sparking wears the switch and electrodes. 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, and burner cap. 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 Cooktop, 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. A clear description of when the problem started and what you were cooking at the time often points the technician straight to the cause.
