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.
