Ice maker is very noisy during operation, with rattling, buzzing, or grinding sounds.

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

• Identify noise source: Remove front and rear panels and run the unit briefly (with caution) to locate the origin of the noise (fan, pump, compressor, or loose panel).
• Tighten hardware: With power off, tighten all accessible screws on panels, fan mounts, and compressor brackets.
• Inspect fans: Check condenser and evaporator fans for wobbling blades, rubbing shrouds, or debris. Straighten blades and remove obstructions. Replace noisy or worn fan motors.
• Check circulation pump: Access the water circulation pump and inspect the impeller for scale or foreign objects. Clean or replace the pump if grinding persists.
• Add vibration pads: Place anti-vibration pads under the feet and ensure the unit is level to reduce transmitted compressor noise.
