How to Fix / Troubleshooting

Safety first: Disconnect power before accessing fans. Use care when adjusting leveling legs.

Step 1 – Level and stabilize

  • Adjust leveling legs so all four corners firmly contact the floor.
  • Verify the unit does not rock when pushed at the corners.

Step 2 – Reposition bottles and shelves

  • Distribute bottle weight evenly across shelves.
  • Ensure shelves are fully seated in their tracks and not warped.

Step 3 – Inspect fans

  • Check evaporator and condenser fans for bent blades or debris.
  • Replace any fan that wobbles or is out of balance.

Step 4 – Isolate from cabinetry

  • Add thin foam or felt strips between the unit and adjacent cabinets where contact occurs.
