Bush oven temperature is uneven; food burns at the back and is undercooked at the front.

Safety first: Allow the oven to cool before internal inspection.

• Check fan operation: In fan mode, confirm that the fan runs. If not, test and replace the motor.
• Inspect fan blade: Ensure the blade is intact and securely fixed to the shaft.
• Door seal: Replace a damaged seal that may allow cold air in.
• Use correct shelf positions: Follow the Bush manual for recommended shelf levels and avoid blocking airflow with oversized trays.
