How to Fix / Troubleshooting
Safety first: Disconnect power and allow the appliance to cool completely. Metal edges behind panels can be sharp; wear cut‑resistant gloves.
- Check ventilation: Ensure front and rear ventilation slots are not blocked by cabinetry, foil, or other objects.
- Inspect cooling fan: Remove the rear or top panel to access the oven cooling fan. Spin the fan blade by hand; it should turn freely without scraping. Clean any heavy grease or dust buildup.
- Test fan operation: With power restored and extreme caution, start a bake cycle and listen for the cooling fan. If it does not run, turn power OFF and test the fan motor for continuity. Replace if open or seized.
- Check thermal devices: Locate any thermal cutouts or thermostats in series with the fan. Test for continuity at room temperature. Replace any open devices with the correct La Cornue parts.
- Reassemble and test: After replacing components, reassemble panels, restore power, and run a high‑temperature bake to confirm the fan runs and F8 does not return.
