La Cornue Cooktop Repair in Houses, Townhomes and Condos
We are independent: not a La Cornue service center, and not authorized by La Cornue. If your cooktop is still inside the La Cornue warranty, go to the manufacturer first. Once it's past that coverage, a model number in your booking lets us source parts ahead of the visit.
How a Cooktop Repair Visit Works
Book the Visit
Call or use the form. Name the make and describe the fault; a model number, if handy, speeds up parts.
Find the Fault
At your place, the technician checks the appliance and whatever feeds it (power, water, drain, gas or venting) until the cause is clear.
Approve the Price
You get a plain explanation and a price for the repair. The work starts only if you say yes.
Fix and Check
The new part is fitted and the appliance is run through a cycle, so you can see it working.
How La Cornue builds its cooktops
Most La Cornue cooktops, whether on the range itself or a separate rangetop, light their gas burners with an electric spark and protect them with a thermocouple. Château ranges can also carry a French top, a thick cast-iron plate heated by a burner at its center. It runs hottest in the middle and cooler toward the edges, and the cook slides pans around to find the right heat. When a burner misbehaves, it's usually one of three things: the igniter gives no spark, the burner goes out once the knob is let go, or the flame is ragged and lifts because ports are blocked or the burner head is sitting wrong. A French top that takes far longer than usual to heat may have fouled ports or weak ignition. Older valves can stiffen, making a knob hard to turn.
Parts that tend to fail on La Cornue cooktops
- Thermocouple not holding the flame
- No spark at the igniter
- Burner ports fouled with residue
- French top slow to reach heat
- Valve stiff and hard to turn

La Cornue Cooktop Repair Questions
The questions that come up most often. Anything not covered here, ask us when you call, or add it to the booking form's notes field.
Have a different question?
Tell us what make it is and what's going wrong. A few things can be settled over the phone, and anything else gets looked at during the visit.
Most likely the thermocouple, which has to heat up and hold the gas valve open after you release the knob. If it's worn, coated with residue or knocked out of the flame, the burner goes out. Cleaning and repositioning sometimes fixes it; otherwise it gets replaced.
It's meant to heat gradually and run hottest in the center, cooler at the edges, and it takes a while to come up to temperature. If the center never gets properly hot, or it's noticeably slower than it once was, the burner, its ports or its ignition may need attention.
