Excessive vibration; bottles rattle and the unit moves or hums loudly against cabinetry.

Safety first: Carefully move the cooler to avoid tipping. Do not lay compressor models on their side.

Steps to reduce vibration:

• 1. Level the unit: Adjust the front and rear leveling legs until the cabinet is stable and does not rock.
• 2. Provide clearance: Ensure the sides and top are not tightly wedged against cabinets. Leave a small gap to prevent resonance.
• 3. Use padding: Place thin foam or felt pads between the cooler and adjacent cabinetry if contact cannot be avoided.
• 4. Secure loose legs: Tighten the lock nuts on leveling legs so they do not shift during operation.
