Ice maker is running but makes a loud buzzing or rattling noise.

Safety first: Unplug the unit before tightening any screws or touching moving parts.

Steps:

• Level the appliance: Place a spirit level on top and adjust the feet or position so the unit is stable and does not rock.
• Check for external vibration: Ensure the ice maker is not touching walls or other appliances that can amplify noise.
• Tighten accessible screws: Inspect the rear cover and side panels for loose screws and gently tighten them.
• Inspect fan (if accessible): Look through the rear grille to see if the fan blades are hitting any wires or plastic. Carefully reposition any obstructions.

Persistent loud mechanical noise may indicate a failing fan motor or compressor, which should be assessed by a technician.
