Ice maker is very noisy during operation; rattling, buzzing, or grinding sounds are heard.

Safety first: Unplug the ice maker before inspecting moving parts.

Check for external causes:

• Ensure the unit is on a stable, level surface. Use a spirit level and adjust feet if provided.
• Remove any objects touching the sides or top that could vibrate.

Inspect internal components:

• Remove the rear/side panel and visually inspect the condenser fan. Remove any debris and ensure the blade is tight on the motor shaft.
• Check compressor mounting grommets; replace if cracked or missing to reduce vibration.
• Listen near the water pump area. A loud grinding or squealing often indicates worn pump bearings; replace the pump if necessary.

Reassemble and test. Persistent loud mechanical noise after these checks may indicate internal compressor issues, which require professional service.
