1. Use correct shelf positions: Follow Rangemaster manual guidance for shelf placement for different cooking modes.
2. Inspect fan cover: Remove and clean the fan cover; ensure all slots are clear.
3. Check fan operation: Confirm the fan runs smoothly and at full speed. Replace the fan motor if weak.
4. Verify sensor placement: Ensure the temperature sensor is correctly clipped and not touching the rear element directly.
