Ice maker is running but makes a loud grinding or rattling noise during operation.

Safety first: Unplug the unit before removing panels or touching moving parts.

Steps to reduce noise:

• Identify noise source: Listen carefully to determine if the noise comes from the rear (fan/compressor) or from the reservoir area (pump).
• Inspect condenser fan: Remove the rear panel and check for foreign objects (plastic, paper) caught in the fan. Remove any debris and ensure the blades spin freely.
• Tighten hardware: Check screws securing the compressor, fan bracket, and panels. Tighten any loose fasteners to reduce vibration.
• Check water pump: If the noise is from the reservoir, inspect the circulation pump for vibration against the housing. Add foam padding or reposition hoses to prevent contact with plastic walls.
• Replace worn components: If the fan motor or pump is noisy even when unobstructed, replace the condenser fan motor or water circulation pump as needed.
