Possible Causes

How to Fix / Troubleshooting

Safety: No high‑voltage work for basic checks.

Steps:

  • Door switch: Check that the door or flap closes fully and that the interior light goes off (if applicable). A faulty door switch can prevent operation.
  • Bin position: Remove and reinsert the ice bin, ensuring it is fully engaged with any sensors or switches.
  • Settings: Verify that the ice function is enabled and no child lock or cleaning mode is active.
  • Power reset: Unplug for 5 minutes, then reconnect and try again.

If the unit still refuses to start, the door switch or control board may require replacement.
