Oven takes an unusually long time to cool down and the cooling fan runs for a very long time after use.

Safety First: The cooling fan is designed to run after use; this is normal unless excessively long or noisy.

• Check vents: Ensure all oven vents are clear and not blocked by cabinetry or objects.
• Fan performance: Listen for unusual noises from the cooling fan. If airflow seems weak or the fan is noisy, replace the cooling fan motor.
• Usage pattern: After very high-temperature or long baking cycles, expect longer cool-down times. This can be normal.
