Possible Causes

Defective compressor overload protector, Incorrect voltage supply, Overheating compressor, Faulty main control board timing

How to Fix / Troubleshooting

Safety first: Unplug the freezer before accessing the compressor area. Compressor surfaces can be hot.

  • 1. Verify ventilation: Ensure adequate clearance around the freezer for heat dissipation. Blocked vents can cause overheating.
  • 2. Check voltage: If possible, have a qualified person verify that the supply voltage is within the specified range for your SMEG model.
  • 3. Inspect overload protector: Remove the start device from the compressor and check the overload for signs of heat damage. Replace if suspect.
  • 4. Clean condenser coils: Dirty coils can cause high compressor temperatures and overload trips. Clean thoroughly.
  • 5. Control board: If mechanical causes are ruled out, the main PCB may be cycling the compressor incorrectly and require replacement.
