La Cornue ranges are largely hand-built, with brass trim, custom enamel, and no fault-code system whatsoever. Diagnosis is mechanical and visual, and parts often come from France on a real timeline. This guide explains how we approach a La Cornue and why parts availability shapes the plan.
Models We Service
We service the full current and recent La Cornue lineup, including the CornuFe and Chateau range series. CornuFe and Chateau ranges here are often decades old, and while enamel and brass work can take months to source from France, burners and valves are serviceable.
How La Cornue Repair Works
La Cornue builds hand-finished French ranges with mechanical controls and heavy ovens, and they report problems through symptoms rather than numeric codes. The diagnosis is hands-on: burners, igniters, thermostats, and the vaulted oven.
A La Cornue has no diagnostics at all, so the table works purely from observable symptoms:
| Symptom | Likely Cause | Typical Fix |
|---|---|---|
| Oven slow to heat or uneven | Worn thermostat or a weak gas igniter | Replace the thermostat or igniter and verify heat |
| Burner will not light or lights unevenly | Clogged port or a failed spark electrode | Clean the port and replace the electrode |
| Oven temperature drifts from the dial | Thermostat calibration or sensor wear | Recalibrate or replace the thermostat |
| Simmer plate or burner runs too hot | Failed valve or worn gas orifice | Replace the valve and confirm the orifice |
| Electric oven element not heating | Failed element or a control fault | Replace the element and test the control |
Common Problems We Fix
La Cornue work is almost entirely mechanical, and these are the repeats:
- Thermostats that drift on the gas ovens.
- Spark electrodes on the burners.
- Gas igniters that weaken over time.
- Burner valves that lose flame control.
- Electric element faults on dual-fuel models.
- Door and hinge service on the heavy ovens.
Maintenance and When to Call
Keep the brass and enamel clean with non-abrasive products and have the burners and valves checked periodically rather than waiting for a failure. Call early on anything mechanical, because parts sourcing sets the timeline more than the labor does. Diagnostic and travel fees, if applicable, are confirmed before the appointment and before repair approval.
