How to Fix / Troubleshooting

Safety first: Unplug the freezer before cleaning coils or accessing the rear compartment.

  • Check installation: Ensure there is adequate clearance around the freezer for ventilation, especially at the rear and sides.
  • Clean condenser: Vacuum dust from condenser coils and fan area.
  • Verify condenser fan operation: With power restored, confirm the fan runs whenever the compressor runs. Replace the fan motor if it does not.

Some warmth on the cabinet is normal, but surfaces too hot to touch indicate a problem. If cleaning and fan replacement do not help, have a technician check the sealed system and heater circuits.
