If every one of them clicks continuously, even the ones that light, the problem is in the module or its supply. If only one clicks, that burner's electrode is wet, dirty or cracked. And if the clicking continues after a burner has settled into a steady flame, the module is not being told that ignition happened — which is the electrode again, not the module. ### What it usually means, by the kind of La Cornue appliance La Cornue sells one appliance in several forms, and the same behavior points at different things on each of them. A built-in side-by-side and an integrated column are not the same service situation, and a dual-fuel range and an induction range fail in different halves. - **Château gas and dual-fuel** — One electrode per burner and a shared module. Which burners click tells you which of the two is the problem. - **CornuFé 90 and 110 dual fuel** — Same architecture, more standardised parts. - **All-induction** — No spark ignition at all. Clicking on an induction top is a relay in the control and a different problem. ### Why continuous clicking is not something to put up with On a range with mechanical valves, holding the knob in while it clicks means gas is flowing whether or not it lights. A few seconds is how a burner is lit; thirty seconds is a quantity of unlit gas in a kitchen that may have a hood running at low speed and a window shut. There is no scenario where persisting is the right answer. Two attempts, then off, then book it. ### What a technician actually does with this The electrode comes out, the ceramic is inspected in daylight, the gap is measured against specification and the ports are cleared and seated. Where the module is suspected it is tested rather than swapped, because a module is a considerably more expensive part than an electrode and it is rarely the answer. The burner is then lit cold and again with the range hot, because a problem that only appears at temperature is missed by a single test. Moisture on the electrode The commonest of all, and it clears on its own once dry. After that it is a part. Cooking residue bridging the gap Spilled sugar or fat carbonises and conducts. The spark goes somewhere useless. A cracked electrode ceramic It arcs to the burner body instead of across the gap. Replaced, not cleaned. Ports blocked near the electrode The gas never reaches the spark even though both are working. The ignition module Only when every burner clicks continuously, and it is the least likely of the five. Which burners click All of them, or one. That answer is most of the diagnosis. Does it stop once lit Clicking that continues after a steady flame is a sensing problem at that electrode. Was anything cleaned recently Water in the wrong place is the leading cause of this call in this climate. Look for residue Around the electrode tip and the nearest ports. Carbonised spill is visible and it conducts. The spark is there and the flame is not What it usually means Clicking after ignition is usually a wet or dirty electrode Clicking on every burner at once points at the module It is a small part and a same-visit job in most cases The check that decides it Light the other burners. If every one of them clicks continuously, even the ones that light, the problem is in the module or its supply. If only one clicks, that burner's electrode is wet, dirty or cracked.

If it clicks and then stops once the flame is steady, that is normal ignition and nothing is wrong. If it keeps clicking with a good flame burning, then the electrode is not sensing the flame it just lit, and that is worth fixing — not because the burner will fail, but because the module is being asked to spark permanently and because the problem that causes it is the same one that will eventually stop the burner lighting at all. ### Can I use the burner while I wait for the visit? If it lights within a couple of seconds and burns cleanly, yes. If it takes repeated attempts, no — use another burner. And if you can smell gas at any point, turn the appliance off at its shut-off valve, ventilate the room and treat it as the gas-smell page rather than this one. --- **[Read full article: Burner clicks but will not ignite](https://la-cornuemiami.support/symptoms/burner-clicks-but-will-not-ignite/)**
