Freezer makes a loud rattling or vibrating noise, especially when the compressor is running.

Safety first: Unplug the freezer before adjusting internal components or removing panels.

• Level the appliance: Use a spirit level and adjust the front leveling feet so the cabinet is stable and does not rock.
• Check internal panels: Ensure all interior shelves, baskets, and rear panels are properly seated and not loose.
• Inspect fans: Access the evaporator and condenser fans. Remove any ice or debris contacting the blades and ensure wiring is tied back.
• Secure tubing: Add foam or clips where refrigerant lines contact the cabinet to reduce vibration.

After adjustments, run the unit and listen for remaining noises. Persistent unexplained vibration may require professional inspection.
