La Cornue ranges are hand-built centerpieces, from the Château to the CornuFé, and they are as much furniture as appliance. Service calls for respect for the finish and the brass, and for genuine OEM parts sourced to the exact range.
We service La Cornue ranges across Chestnut Hill with careful handling and model-specific components, working from symptoms rather than a code chart.
Models We Service
We work across the current and recent La Cornue lineup, including:
- Château series ranges (75, 90, 120, 150)
- CornuFé 90 and 110 ranges
- Grand Palais 180
- Custom vaulted-oven configurations
- Gas, dual-fuel, and induction top options
Book a Diagnostic Visit
We confirm the fault, then quote the repair in writing. Diagnostic and travel fees, if applicable, are confirmed before the appointment and before repair approval.
Symptoms & Fixes
Classic La Cornue ranges are largely mechanical and do not use electronic fault codes, so we diagnose from symptom to cause to fix.
| Symptom | Likely Cause | What We Do |
|---|---|---|
| Oven will not reach temperature | Weak igniter, thermostat, or gas valve fault | Replace the igniter or thermostat, test the valve |
| Burner will not light | Fouled burner or a failed spark electrode | Clean the burner, replace the electrode |
| Uneven baking in the vaulted oven | Thermostat calibration or burner alignment | Recalibrate the thermostat, align the burner |
| Simmer will not hold | Worn gas valve | Replace the valve to restore low-flame control |
Common Problems We Fix
The La Cornue repairs we handle most often address:
- A vaulted oven that will not reach or hold temperature
- A burner that will not light or hold a simmer
- Brass or enamel wear that needs careful handling
- A thermostat that has drifted out of calibration
