Service and Repair Costs
Annual Professional Service: from $200
La Cornue recommends periodic professional servicing for their rangetops. A comprehensive service visit includes burner jet cleaning and inspection, gas pressure verification, ignition system testing, valve operation check, and overall cleaning of accessible internal components. This preventive service extends component life and catches developing issues before they become costly failures.
Burner Ignition System Repair: from $200
High-output rangetop burners cycle through more thermal stress than standard residential burners, which accelerates wear on igniter electrodes and caps. Ignition system repairs for rangetops follow similar pricing to cooktop ignition work, though the higher burner count means issues sometimes affect multiple burners simultaneously, adding to parts costs.
Gas Valve Service or Replacement: from $350
La Cornue rangetop burner valves control the full output range from a precise simmer to 18,000–22,000 BTU maximum output. Valve service — cleaning, adjustment, and calibration — is often sufficient to restore smooth operation. Full valve replacement is reserved for valves that have developed internal wear or leaks. All gas system work requires a licensed gas technician.
Griddle Element or Thermostat (Dual Fuel): from $400
Rangetops with electric griddle sections have an additional electrical service scope. Griddle heating elements and thermostats are serviceable components. A failed thermostat — the most common griddle issue — prevents the griddle from maintaining accurate temperature. Element replacement is warranted when the element has failed open (no continuity).
