Ice maker makes a high-pitched squealing or chirping noise during operation.

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

• Identify source: Listen carefully to determine whether the noise comes from the rear (fan/compressor) or the reservoir area (pump).
• Inspect fan: Remove the rear panel and check that the fan blades are not rubbing against the shroud or wires. Clean any debris.
• Check pump: Access the pump and ensure nothing is caught in the impeller.

If the squealing persists and is clearly from a motor, the affected fan or pump motor bearings are likely worn and the component should be replaced to prevent failure.
