How to Fix / Troubleshooting

Safety: Unplug the refrigerator before accessing the control board.

  • Power reset: Unplug the unit for 10–15 minutes to reset the control. Plug back in and listen for compressor and fan start within 5–10 minutes.
  • Check temperature settings: Ensure the unit is not in a special mode (vacation, Sabbath, demo) that disables cooling.
  • Inspect control board: Remove the control cover and look for burnt components or loose connectors. Reseat all harnesses.
  • Sensor faults: If any thermistor is reading incorrectly, the board may prevent compressor operation. Test and replace faulty sensors.
  • Board replacement: If the board does not energize outputs despite correct inputs, it likely needs replacement by a technician.
