E3 error code and interior fan does not run or runs erratically

Safety: Disconnect power before working near the fan or evaporator.

• Listen for fan operation: With the door closed and unit powered (before unplugging), listen for the evaporator fan. If silent when compressor is running, suspect a fan issue.
• Access fan assembly: Remove interior shelves and the rear inner panel to expose the evaporator and fan housing.
• Check for obstructions: Look for ice buildup around the fan, loose wiring, or foreign objects. Carefully clear any ice with warm (not hot) water and a cloth—do not use sharp tools.
• Inspect wiring: Ensure the fan motor connector is fully seated and wires are not damaged.
• Test fan motor: With the fan disconnected, measure resistance across the motor terminals. An open circuit indicates a failed motor. If you have a safe low-voltage test source (per manufacturer specs), you can bench-test the fan.
• Replace fan motor: If defective, install a new Beko evaporator fan motor. Reassemble the housing and ensure the blades spin freely.
• Control board check: If the fan tests good but does not receive power when it should, the main PCB fan output may be faulty and require replacement.
