Ice maker is very noisy during operation (grinding, rattling, or loud humming).

Safety first: Unplug the unit before tightening hardware or removing covers.

Steps to reduce noise:

• Level the unit: Use a spirit level to ensure the ice maker is level front-to-back and side-to-side. Adjust leveling feet as needed.
• Tighten fasteners: Check and tighten screws securing panels, compressor mounts, and internal brackets.
• Inspect fans: Access condenser and evaporator fans. Remove any debris and check for wobble or grinding. Replace noisy fan motors.
• Check harvest mechanism: Look for ice pieces jammed in the rake or tray. Clear obstructions and run a test cycle.
• Isolate compressor: Ensure rubber grommets are intact under the compressor. Replace if hardened or missing.

When to call a technician: Persistent loud humming or knocking from the compressor may indicate internal failure and requires professional service.
