Caple oven not heating evenly; food is burnt at the back and undercooked at the front.

Safety first: Turn off the oven and allow it to cool before inspection.

• Check fan operation: Run the oven in fan mode and observe through the door that the fan is spinning at a steady speed. Any hesitation or noise suggests a failing motor.
• Clean vents: Remove shelves and clean all visible vents and slots in the rear and sides of the cavity to restore airflow.
• Inspect fan blade: With power off, remove the rear panel and check that the fan blade is not bent or loose on the shaft. Tighten or replace as needed.
• Use correct shelf positions: Follow the Caple manual for recommended shelf levels and avoid blocking the fan with large trays.
