How to Fix / Troubleshooting

Safety first: If you need to remove the control panel, unplug the unit first.

  • Check for control lock: Refer to the user manual to see if a lock function is active (often indicated by a symbol). Disable it using the specified button combination.
  • Power cycle: Unplug the ice maker for 5 minutes, then reconnect and try again.
  • Test start button: If accessible, press the start button repeatedly and feel for a positive click. If it feels loose or unresponsive, the button or UI board may need replacement.
  • Board inspection: If the start circuit is suspected, a technician should test the control board relays and replace the PCB if faulty.
