E8 error; freezer may be too warm or too cold; fan may run at incorrect speed.

Safety: Disconnect mains power before accessing the fan area.

• Access the fan: Remove the internal rear panel of the freezer to expose the evaporator fan motor and evaporator.
• Check for ice build-up: Look for heavy frost or ice blocking the fan. If present, fully defrost the unit and check the defrost system (heater, sensor, thermostat).
• Spin the fan by hand: The blades should rotate freely without scraping. If stiff or noisy, the motor bearings may be worn.
• Test the motor: With the motor disconnected, measure resistance across the motor terminals. An open circuit indicates a failed motor. On DC fans, also check for correct supply voltage from the control board when powered.
• Inspect wiring: Ensure the harness from the fan to the main PCB is intact and connectors are secure.
• Replace faulty motor: Install a new evaporator fan motor if defective. Ensure the fan shroud and blades are correctly positioned to avoid noise and vibration.
• Control board: If the motor and wiring are good but the fan never receives power, the main control PCB may have a failed fan driver.
