Freezer vibrates excessively or hums loudly, especially when compressor starts

Safety first: Unplug the freezer before adjusting rear components.

Steps:

• Level the unit: Use a spirit level and adjust the front feet until the cabinet is stable and slightly tilts back.
• Clearances: Ensure the freezer is not touching the wall or adjacent furniture. Maintain recommended clearances.
• Check rear panel: Tighten any loose screws on the rear cover or compressor bracket.
• Inspect compressor mounts: Replace worn rubber mounts if the compressor is transmitting vibration to the cabinet.
