Daniel Thornton Key Takeaways
- La Cornue repair costs are higher than standard appliance repairs, reflecting both parts cost and the specialized expertise required for hand-built French appliances.
- Igniter and sensor replacements are on the lower end of the cost spectrum (from $300), while control board and complete burner assembly replacements can reach from $800.
- The diagnostic fee (from $100) is almost always applied toward the repair cost by reputable La Cornue service agents.
- Given that La Cornue ranges start at $8,000 and Château models can exceed $50,000, even a $1,200 repair represents a fraction of appliance value.
- Always request an itemized estimate that separates parts cost from labor — some parts have long lead times from France that affect repair timelines.
The Bottom Line
La Cornue range repairs are premium-priced but represent exceptional value relative to appliance cost. Any repair under $1,500 on a range worth $10,000 or more is economically straightforward to justify.

Cost by Repair Type
Igniter Replacement: from $300
Oven igniter replacement is the most common La Cornue range repair. Parts cost from $80 for OEM La Cornue igniters; labor for a qualified technician runs 1–1.5 hours. This is a reliable, cost-effective repair with a clear outcome — the igniter either works or it doesn't, and replacement resolves the problem definitively.
Temperature Sensor Replacement: from $250
RTD temperature sensor replacement is straightforward on most La Cornue models. The sensor is accessible from the oven interior, and replacement takes approximately one hour. OEM sensors run from $60. This repair is often combined with a calibration check and adjustment, typically included in the labor rate.
Bake or Broil Element Replacement (Dual Fuel): from $350
Heating elements for CornuFé and Château dual-fuel models are sourced through La Cornue's authorized parts network. OEM elements for La Cornue models run from $120; installation is 1–1.5 hours of labor. Given the oven access required and the importance of correct element fit in a vault oven cavity, OEM parts are strongly recommended over aftermarket alternatives.
Control Board Replacement: from $700
Electronic control board replacement is among the more costly La Cornue repairs. Control boards for these appliances are engineered specifically for each model and sourced from France, with parts costs ranging from from $400. Labor for board replacement and recalibration adds another from $200. Boards are typically only replaced after confirming the board is the fault source through diagnostic testing.
Gas Valve or Burner Assembly: from $450
Gas valve replacement involves working with the gas supply system and must be performed by a licensed gas technician. Burner assembly replacements for individual cooking burners are more accessible repairs. La Cornue's precision brass burner heads are durable components that rarely require full replacement — more commonly the burner cap, jet, or igniter electrode is the component that needs replacement.
Door Hinge Assembly: from $400
Vault oven door hinge replacement is a moderately complex repair due to the weight of La Cornue doors and the precision alignment required. OEM hinge assemblies run from $150 per side; labor is 2–3 hours including alignment and adjustment. A properly executed hinge replacement should restore the distinctive, balanced door feel these ovens are known for.
Get an Accurate Quote
Repair costs vary by model, parts availability, and local labor rates. To get an accurate estimate for your La Cornue range, contact a certified service technician for a diagnostic visit. Most reputable service agents apply the diagnostic fee toward the repair cost. When requesting a quote, ask specifically whether parts are OEM La Cornue components — aftermarket alternatives may be available for some parts, but they carry fit and warranty risks on precision-engineered appliances.
