Oven display shows F8, cooling fan may run continuously or not at all, oven may shut down during use.

Safety first: Switch off power and allow the oven to cool fully before accessing internal components.

• Check air flow: Ensure that the front ventilation slots are not blocked by cabinetry or objects. Poor airflow can cause overheating and F8 errors.
• Access the cooling fan: Remove the top cover of the oven or range to reach the tangential cooling fan assembly above the oven cavity.
• Inspect the fan: Try spinning the fan wheel by hand (with power OFF). It should rotate freely without scraping. Clean any accumulated grease or dust from the blades.
• Test the motor: Disconnect the fan and measure its resistance. An open circuit indicates a failed motor. If you are qualified, you can briefly power the fan with the correct mains voltage to confirm operation.
• Check wiring and control: Inspect the harness and connectors to the fan. If the motor is good but never receives voltage when the oven is hot, the control board’s fan driver (relay/triac) may be defective and require board replacement.

Warning: Do not operate the oven with a non-functioning cooling fan; this can overheat electronics and surrounding cabinetry.
