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

Safety first: Most vibration fixes can be done with power on, but unplug before reaching near moving parts.

• Step 1 – Level the freezer: Use a level on top of the cabinet. Adjust leveling legs so the unit is stable and does not rock.
• Step 2 – Check rear panel: Ensure the rear access panel is securely fastened and not vibrating.
• Step 3 – Inspect internal panels: Inside the freezer, verify that shelves and the rear evaporator cover are firmly seated.
• Step 4 – Isolate tubing: In the rear compartment, gently reposition any copper lines touching the cabinet and insert foam spacers.

Persistent vibration after these steps may indicate a failing fan motor or compressor, which should be checked by a technician.
