How to Fix / Troubleshooting

Warning: Sealed refrigeration system work (refrigerant, compressor, brazed joints) must be performed by an EPA-certified refrigeration technician. Do not attempt to open the sealed system yourself.

  • Basic checks: Unplug the unit and clean the condenser coils thoroughly with a brush and vacuum. Ensure the condenser fan is operating correctly and that there is adequate ventilation around the unit.
  • Check ambient temperature: Make sure the ice maker is not installed in a very hot or enclosed space, which can cause high-pressure faults.
  • Restart and observe: After cleaning and ensuring good airflow, restart the unit. If E12 returns and ice production remains poor, a sealed system issue is likely.
  • Call a technician: Contact a qualified refrigeration technician to check system pressures, refrigerant charge, and compressor performance. They can locate leaks, repair, evacuate, and recharge the system as needed.
