Freezer shows E5 and compressor may not run or runs erratically

Safety first: Unplug the appliance. Compressor and inverter circuits carry mains voltage; do not work live.

Steps:

• Ventilation check: Ensure there is adequate space around the freezer and that the condenser at the back is not blocked with dust.
• Power reset: Unplug for 15 minutes and reconnect. Listen for the compressor attempting to start.
• Inspect compressor area:
  • Remove the lower rear cover to access the compressor compartment.
  • Check the start relay/PTC and wiring for signs of burning or melting.
• Replace start device (non-inverter models): If the PTC/relay is visibly damaged or rattles when shaken, replace it with a genuine Beko start device.
• If the unit uses an inverter module, do not attempt internal repairs; the module or compressor may be faulty and requires professional diagnosis.
• If E5 persists after replacing the start device, the compressor or main control board is likely defective; contact a refrigeration technician.
