LG Oven Error Code F17 — Convection Fan Error

Moderate Repair 30–60 minutes Tools: Phillips screwdriver

What this means

The F17 error code indicates the convection fan motor has failed or is not detected during a convection bake or roast cycle. The convection fan circulates hot air evenly throughout the oven cavity. Without it, convection cooking cannot function properly. The fan motor, wiring, or control board relay may be at fault.

Step-by-step fix

3 steps

Reset the oven

Press CLEAR/OFF. Reset the circuit breaker for 30 seconds and restart.

Test with standard bake

Try running the oven in standard (non-convection) bake mode. If standard bake works, the issue is isolated to the convection fan.

Listen for the fan

Start a convection cycle and listen at the back of the oven for the fan motor spinning. If silent, the motor may be stuck or burned out.

When to call a professional

Convection fan motor replacement requires removing the oven back panel and is best handled by a technician.
