How to Fix / Troubleshooting

Safety first: Disconnect mains power and allow the oven to cool before inspecting internal components.

Steps to improve heat distribution:

Check convection fan operation: Run the oven in convection mode and verify that the fan runs. If not, test and replace the convection fan motor.
Inspect air vents: Ensure that the air inlets and outlets around the convection fan cover are not blocked by foil or heavy grease. Clean thoroughly.
Check rack placement: Use the recommended rack positions from the user manual. Avoid placing large trays directly against the back wall, which can disrupt airflow.
Test convection element: If the fan runs but convection is weak, test the ring element and replace if open or weak.
Test: After adjustments, bake a test item (e.g., a tray of biscuits) and check for even browning.

Oven temperature is uneven; food is overcooked at the back and undercooked at the front.
