Possible Causes

How to Fix / Troubleshooting
Safety: Turn off power before removing interior panels.
- Use convection mode: For more even cooking, use convection bake/roast if available and verify that the convection fan runs.
- Inspect fan cover: Remove the rear interior panel and check for grease or debris blocking the convection fan intake or exhaust slots.
- Check fan operation: Ensure the convection fan spins freely and runs during convection modes. Replace the motor if not operating correctly.
- Rack placement: Use the rack positions recommended in the Sub-Zero manual and avoid overcrowding the oven, which can block airflow.
