Answer to continue safely
Is it safe to keep using?
Yes. The oven can be used safely in conventional (non-convection) bake and broil modes. Only the convection function is affected. Avoid convection modes until the fan is repaired.
Can I reset the code?
Yes. The error may clear after a power cycle, and the fan may work intermittently if the issue is bearing-related. However, it will progressively worsen.
When to stop immediately?
Stop if you notice: If you hear loud grinding or metal-on-metal sounds, stop using convection modes immediately., If you smell burning from the rear of the oven (motor burning), disconnect power..
Symptoms You May Notice
Uneven cooking and browning results
Food cooks unevenly with hot spots and cold spots, or one side of dishes browns significantly more than the other.
No fan noise during convection mode
The oven is silent when set to a convection mode where you would normally hear the fan running.
Fan makes grinding or squealing sounds
The convection fan produces abnormal mechanical sounds, indicating bearing wear or blade obstruction.
E2 appears during convection cycle
The error appears specifically when convection mode is selected or during a convection cooking cycle.
Possible Causes
Worn fan motor bearings
The motor bearings have degraded from heat exposure, causing the motor to seize or run at reduced speed.
Requires ProfessionalObstructed fan blade
Food debris, foil, or a dislodged oven component is physically blocking the fan blade from spinning.
DIY PossibleFailed motor winding
The electrical windings inside the fan motor have burned out, usually from overheating or age.
Requires ProfessionalSafe Checks You Can Do
-
1
Listen for the fan
Set the oven to convection bake and listen carefully at the rear vent for fan sound. Compare to normal operation.
A working fan creates a gentle but audible whooshing sound from inside the oven.
-
2
Check for obstructions
With the oven off and cool, check the fan cover at the rear wall of the oven. Look for any debris or items that could block the fan.
Small items like skewers or aluminum foil pieces can sometimes get pulled into the fan area.
-
3
Try non-convection mode
Test conventional bake (no convection) to confirm the oven heats normally without the fan.
If conventional bake works fine, the issue is isolated to the convection fan system.
When to Call a Professional
Contact a qualified technician if:
- Fan motor replacement requires removing the rear oven panel for access.
- Motor amperage testing confirms whether the motor is drawing excess current.
- On some La Cornue models, the fan blade and motor are a combined assembly requiring full unit replacement.
