High-pitched whine or rattling noise from the back of the unit during operation.

Safety first: Unplug the unit before touching the fan or compressor area.

Steps to address rear noise:

• 1. Level the unit: Ensure the ice maker is on a flat, stable surface. Adjust feet or place a thin pad under corners to stop rattling.
• 2. Inspect the fan: Remove the rear panel and check that the fan blade is not rubbing against the shroud or wires. Bend the shroud slightly or reposition wires as needed.
• 3. Check fan bearings: Spin the fan by hand. If it feels rough or wobbly, replace the condenser fan motor.
• 4. Tighten compressor mounts: Carefully tighten the compressor mounting bolts if they are loose, but do not overtighten and stress the refrigerant lines.
• 5. Dampen panel vibration: Add thin foam or rubber strips between vibrating panels and the frame if necessary.

Note: Persistent loud compressor noise may indicate internal compressor damage and should be evaluated by a technician.
