Ice maker is very noisy during operation (grinding, rattling, or buzzing)

Safety first: Unplug the unit before touching any moving parts. Do not operate with panels removed unless necessary for diagnosis, and keep hands clear of fans.

• Step 1 – Isolate noise source: With the front panel removed and power restored briefly, listen carefully to determine if the noise comes from the pump, fan, or compressor area. Then disconnect power again.
• Step 2 – Check circulation pump: Inspect the pump for debris in the impeller and for signs of wear. If the pump is noisy even when clear, replace it.
• Step 3 – Inspect condenser fan: Ensure the fan blade is tight on the motor shaft and not rubbing against shrouds or wiring. Tighten or reposition as needed.
• Step 4 – Secure tubing and panels: Look for copper lines or harnesses vibrating against metal panels. Add foam sleeves or clips to prevent contact. Tighten any loose screws.

After adjustments or part replacement, reassemble panels and verify that noise levels are normal during a full cycle.
