How to Fix / Troubleshooting

Safety: Unplug the unit before checking internal connections.

  • Inspect harnesses: Check all wiring harness connectors on the main control PCB, sensors, pump, fan, and compressor start device. Reseat each connector firmly.
  • Look for corrosion: Clean any corroded terminals and replace connectors if necessary.
  • Tap test: With the unit running (use caution), gently tap the control panel and rear panel. If operation changes, a loose connection or failing relay is likely; replace the main control PCB.
  • Monitor cycles: After reseating connections, monitor several full ice cycles to confirm consistent operation.
