How to Fix / Troubleshooting

Safety first: Unplug the freezer before cleaning or touching components near the compressor.

  • Improve ventilation: Ensure the freezer is not pushed tightly against the wall and that side and top clearances meet Ariston specifications.
  • Clean condenser: Vacuum and brush dust from condenser coils and the compressor area.
  • Check condenser fan: On models with a fan, verify it runs when the compressor is on. If not, the fan motor may need replacement.
  • Allow cooling: Leave the unit unplugged for 30–60 minutes to let the compressor cool, then reconnect and observe operation.

When to call a technician: If E5 recurs and the compressor overheats or makes unusual noises, a sealed-system specialist is required to check refrigerant pressures and compressor health.
