How to Fix / Troubleshooting

Safety first: Unplug the Klarstein ice maker before tightening screws or touching moving parts.

Level the unit: Ensure the ice maker is on a stable, level surface. Adjust feet if provided.
Check for loose parts: Gently shake the cabinet and listen for rattles. Tighten any loose screws on panels or brackets.
Isolate noise source: Run the unit with the cover removed (if safe) and listen to identify whether the noise comes from the fan, pump, or tray motor.
Replace noisy components: A grinding or squealing fan or pump should be replaced. A clicking/grinding during tray rotation suggests a worn tray motor gear set.

Persistent loud humming from the compressor with no cooling indicates a serious compressor issue requiring a technician.

Ice maker is very noisy during operation; rattling, grinding, or loud humming sounds.
