La Cornue repair services on this site cover the full range of hand-built French cooking appliances — stoves, ranges, vaulted ovens, cooktops, range tops, and range hoods — and nothing outside the kitchen cooker. Each appliance is assembled to order by the Compagnons in Saint-Ouen-l’Aumône, so every service call begins by identifying the precise build rather than assuming a standard layout. That discipline matters because a single La Cornue can pair gas burners, an electric or multifunction oven, and an induction top, each needing parts matched to the installed fuel and configuration.
Which repair service you need
We break the work into focused services so you reach the right technician faster. Whole-appliance gas and dual-fuel concerns belong with stove repair, while the Château and CornuFé cookers are covered by range repair. The sealed radiant “voûte” cavity is handled by oven repair, the modular hob by cooktop repair and range top repair, and the Château and CornuFé Hood Collection units by range hood repair. The lines overlap because the appliances do, so we coordinate between services when a fault spans the oven and the hob.
How we diagnose a La Cornue
Every repair starts with model identification and, on electronic builds, reading any stored fault codes such as E2, U400, or Er from the induction top or multifunction oven. We measure glow-bar igniter amp draw rather than judging by the glow, check thermostat and sensor calibration against a reference thermometer, and verify flame quality and air-shutter settings for the installed fuel before condemning any part. The hi-limit safety thermostat (part reference 06ELTS01) trips on overheat and lights a red indicator; it is reset or replaced only after the overheat cause is found. Where a symptom needs explaining first, our diagnostics library walks through the likely causes.
Protecting the finish during a repair
On a La Cornue, the repair is not finished until the cosmetics are intact. Vitreous enamel chips from impact or thermal stress and is replaced as a panel rather than refinished in place; polished or brushed brass burners, rails, and trim discolour under heat and harsh cleaners and are restored with correct brass care, never abrasives; and a cast-iron French Top relies on seasoning and on staying dry, since standing water and thermal shock cause the cracking, warping, and rust we routinely repair. Whether the trim is brass, nickel, chrome, or copper, each surface is handled on its own terms so a working repair never leaves a visible scar on a piece that doubles as furniture.
Genuine parts and the craftsmanship behind them
Because each cooker is hand-built with brass, cast iron, and vitreous enamel, repairs use OEM components matched to the specific build — orifices, valves, igniters, elements, induction coils and sensors, blower motors and capacitors, and the 06ELTS01 hi-limit thermostat. Fitting the wrong orifice or regulator after an LP/NG conversion ruins flame quality, and an approximate board substitution can lock out a multifunction oven, so we do not improvise on a made-to-order appliance. You can confirm specifications and finishes against the model lineup or the official La Cornue website before we begin.
Warranty, coverage, and booking
La Cornue cooking appliances carry a 5-year parts-and-labour warranty, and genuine parts and authorized service are coordinated through the National Service Center at 1-877-522-6768. Our factory-aware technicians service every La Cornue type across all 50 US states, and same-day booking is available through our 24/7 form. Diagnostic service starts from $129, and any repair quote is given before work begins — we never quote a fixed price sight unseen, and the final cost depends on the part and the appliance involved. When you are ready, schedule your repair and tell us the model, fuel, and finish so the technician arrives with the right parts in hand.
