How to Fix / Troubleshooting

Safety: Unplug the freezer before accessing the display or control board.

  • Power cycle: Unplug for 5 minutes and plug back in to see if the display resets.
  • Check harness: Remove the display panel and rear control board cover. Inspect and reseat the harness between the display and main board.
  • Sensor check: If the display shows dashes where temperature should be, the cabinet sensor may be open. Test and replace the cabinet temperature sensor if faulty.

  • Main board: Persistent communication errors after replacing the display may require main control board replacement.
