La Cornue Range Not Igniting in Orange County — What We Found

Why is my La Cornue range clicking but not igniting?

When a La Cornue range clicks but won’t ignite, the problem is almost always one of three things:

• a failed ignition module
• a worn or contaminated igniter electrode
• moisture trapped in the ignition system after cleaning

Recently, we went to see a client in Orange County whose La Cornue range wouldn't light. It turned out to be the Soufflet ignition module. This is where you can change how sparks get to all the burners. Because it was broken on the inside, it clicked but didn't spark reliably at the electrode.

Here’s what we found, what we checked first, and what you should know before calling anyone to service your La Cornue appliance.

‍

What makes La Cornue ignition different from standard ranges

La Cornue ranges — both the handcrafted Château series and the more accessible CornuFé series — use a proprietary ignition system that differs significantly from what you’d find on a Thermador, Wolf, or Viking range. The Soufflet ignition module controls spark delivery to all burners simultaneously from a single unit. When this module develops a fault, it doesn’t typically fail completely — it often continues generating a signal (hence the continuous clicking) while losing the ability to produce a consistent spark at the electrode itself.

This is important because it means a La Cornue that’s clicking isn’t necessarily a reassuring sign that “electricity is getting through.” It may mean the module is working partially and failing at the critical moment of spark delivery. A technician who mistakes the clicking for proof of a functioning ignition system will misdiagnose the cause and replace the wrong component.

La Cornue parts also come through a specific supply pipeline via Middleby, the parent company of La Cornue in the US market. The Soufflet module, igniter electrodes, burner heads, and gas valves are not available at standard appliance parts distributors — they need to be sourced correctly. A technician ordering a generic ignition module that “fits” is not the same as ordering the correct La Cornue component.

‍

What we check first on a La Cornue ignition call

Before assuming a component has failed, we work through the causes that don’t require any parts:

• Burner cap alignment — La Cornue burner caps must seat precisely in their correct position. A cap that’s slightly rotated or not fully seated will prevent ignition even with a perfectly functioning ignition system. Each cap has an orientation slot that aligns with the burner body.

• Moisture in the ignition system — La Cornue ranges are often cleaned carefully by homeowners who care about their equipment, and water that enters the burner wells or the igniter housing can cause continuous clicking without ignition for 24–48 hours. If the range started clicking after cleaning, this is the first thing to rule out. Turn all burners to the off position, leave the range off for several hours, and try again. Gentle heat from the oven at a low temperature can accelerate drying.
  ‍
• Electrode gap and contamination — the igniter electrode sits adjacent to the burner and must maintain a precise gap to produce a reliable spark. Grease buildup, food debris, or physical damage to the porcelain insulator can prevent a proper spark even when the module is functioning correctly.
  ‍
• Gas supply pressure — a spark without ignition can also mean the gas isn’t reaching the burner in the right volume or pressure. We check the shutoff valve position and the inlet pressure before assuming the ignition system is at fault.

‍

What the repair looked like

• Problem reported: La Cornue CornuFé range clicking continuously across all burners, no flame on any burner, gas smell present briefly at startup
• What we ruled out first: Burner cap alignment confirmed correct, no moisture present (range hadn’t been cleaned recently), electrode condition inspected and found intact
• Root cause: Soufflet ignition module fault — generating a spark signal but not producing reliable spark at the electrode on any burner
• Parts replaced: Soufflet ignition module (sourced through Middleby supply channel)
• Additional work: All five burners tested individually after replacement, flame pattern and height verified on each burner, gas pressure confirmed
• Result: All burners lighting cleanly on first attempt before technician left
• Time on site: Approximately 95 minutes including diagnostic and repair

La Cornue CornuFé vs Château — ignition differences worth knowing

Both La Cornue series share the same Soufflet ignition platform, but there are practical differences in how they present with ignition problems.

The CornuFé series — the more commonly serviced La Cornue in Orange County homes — is a semi-professional range with more conventional service access. The ignition module is accessible without extensive disassembly, and burner components follow a more standard pattern despite being proprietary parts. CornuFé ignition failures are the most common La Cornue service call we see.

The Château series is a fully handcrafted range with a gravity-convection vaulted bake chamber and more complex internal architecture. Ignition service on a Château requires more time and care due to the bespoke construction — access to components takes longer, and reassembly must be done with attention to the cosmetic finish. Château burner heads and gas valves have a 5–8 year service life in regular use and are replaced as part of planned maintenance rather than emergency repair on well-maintained units.

If you’re not sure which series you have, the range’s model plate is typically located on the inside of the storage drawer or on the back of the unit. Bringing that model number when you call speeds up the diagnostic and helps us arrive with the correct parts.

‍

Is it safe to keep using the range if one burner lights and others don’t?

If some burners are igniting normally while others won’t light, the range is not dangerous to use on the functioning burners as long as you’re not detecting any gas smell at the non-functioning burners when they’re turned to the on position. Gas smell without ignition means gas is being released and not burned — stop using the range entirely and call for service promptly.

If there’s no gas smell and the non-functioning burners are simply not sparking, you can continue using the working burners cautiously while scheduling a repair. Don’t attempt to light a non-sparking burner with a match or lighter without confirming there’s no gas flow issue first.

If all burners have stopped igniting simultaneously — as in the call above — the cause is almost always the ignition module rather than individual burner components, since a module fault affects all burners at once.

Frequently asked questions

Why does my La Cornue range keep clicking but not light?
Continuous clicking without ignition on a La Cornue usually means a faulty Soufflet ignition module, a contaminated or damaged igniter electrode, or moisture in the ignition system after cleaning. If all burners are affected simultaneously, the module is the most likely cause.

Can I light my La Cornue burner manually if it won’t spark?
Only if you’re certain there’s no gas smell at the burner when turned to the on position. If gas is present without ignition, don’t attempt manual lighting — turn the burner off and call for service. If the burner simply isn’t sparking but there’s no gas smell, a long lighter can be used cautiously, but diagnosing and fixing the ignition issue is the right long-term solution.

How much does La Cornue ignition module replacement cost?
La Cornue parts are brand-specific and priced accordingly — more than equivalent components on standard appliance brands. We provide a written estimate before doing any work so there are no surprises. The diagnostic fee is waived when you proceed with the repair.

Why did all my burners stop working at the same time?
When all burners fail simultaneously rather than one at a time, it almost always points to the ignition module rather than individual burner components. Individual burner failures (electrode damage, gas valve wear) tend to affect one burner at a time.
