Important Safety Warnings
- Electrical components should only be tested by qualified professionals.
- Non-OEM parts can void your warranty.
What You'll Need
Step-by-Step Guide
Igniter Modules
The most frequently replaced component. Constant thermal cycling, spill exposure, and normal wear gradually weaken performance.
RTD Temperature Sensors
Critical to oven temperature accuracy. These should be tested during any annual maintenance visit.
Thermocouples
Safety devices that detect flame presence. A burner that lights but immediately extinguishes is the classic symptom.
Control Boards
The brain of the appliance. Susceptible to power surges and moisture ingress.
Door Gaskets
Wear items that should be inspected annually. Damaged gaskets reduce efficiency and cause overheating.
Understanding La Cornue Part Longevity
La Cornue appliances are built to last decades — but no mechanical component lasts forever. Catching problems early avoids costly secondary damage.
1. Igniter Modules
High-use components that eventually fail due to heat stress.
2. RTD Sensors
Drift over time, leading to temperature inaccuracies.
3. Control Boards
Manage every electronic function; replacement requires specific model firmware.
