Freezer cabinet or door vibrates excessively; unit seems to 'walk' or move slightly when compressor starts.

Safety first: Unplug the freezer before adjusting feet to avoid accidental movement while running.

Step-by-step checks:

• 1. Level the freezer: Place a level on top of the cabinet. Adjust the front leveling feet until the unit is stable and does not rock.
• 2. Check rear supports: Ensure rear rollers or feet are intact and resting firmly on the floor.
• 3. Isolate from surroundings: Move the freezer slightly away from walls or cabinets that may transmit vibration.
• 4. Add anti-vibration pads: Place rubber pads under the feet if the floor surface is particularly resonant.

When to call a technician: If vibration persists despite proper leveling, there may be an internal mechanical issue that requires professional inspection.
