Why Proper Maintenance Matters

Routine maintenance of your Breezaire unit is crucial for several reasons:
- Preserves wine quality: Stable temperature and humidity prevent cork deterioration and flavor loss.
- Prevents costly breakdowns: Regular upkeep helps you catch minor issues before they become major repairs.
- Extends unit lifespan: Clean, well-maintained components reduce wear and tear.
- Optimizes performance: Features like the Sentry III control system and vibration-free operation work best when the unit is well cared for.
Routine Maintenance Checklist
Staying on top of these routine tasks will keep your Breezaire unit in peak condition. Many of the maintenance steps outlined here apply directly to the popular Breezaire WKL Series wine cellar cooling systems. Check your model’s specifications for detailed instructions.
-
Clean Air Filters and Vents
- Dust and debris can restrict airflow, causing the unit to work harder and less efficiently.
- Check filters and vents monthly; clean or replace as needed.
-
Inspect for Blocked Airflow
- Ensure there’s nothing obstructing the intake or exhaust vents.
- Blocked airflow can trigger the unit’s protection features and affect cooling.
- If your unit keeps shutting off unexpectedly, find solutions in our wine cooling keeps shutting off resource.
-
Vacuum Condenser Coils
- Dust buildup on condenser coils reduces cooling efficiency.
- Gently vacuum the coils every 3–6 months, or more often in dusty environments.
-
Check Humidity Levels
- The unit maintains humidity between 50% and 75%—ideal for wine storage.
- In very dry climates, add moisture using a small, open water container for natural evaporation (avoid humidifiers).
- If you’re struggling to maintain the right humidity in your wine cellar, see our detailed tips in this guide to fixing wine cellar humidity problems.

-
Clear the Drain Tube (if applicable)
- Some models have a drain tube to remove condensation.
- Inspect regularly for clogs; ensure the hose is routed to an approved drain with an air break.
- If you notice water pooling or leaks, learn how to address them in our wine cooling unit leaking guide.
-
Monitor for Unusual Noises or Vibrations
- Breezaire units are designed for quiet, vibration-free operation.
- New or loud noises may indicate a maintenance issue.

Monitoring and Adjusting Temperature

Breezaire’s Sentry III control system makes temperature management easy and precise:
- Checking the Temperature: Use the digital display to monitor the current cellar temperature.
- Adjusting the Set Point: Press and hold the "SET" button, then use "COOLER" or "WARMER" to adjust the desired temperature. Release "SET" to save.
- Recommended Range: Keep your cellar between 50°F and 60°F for optimal wine aging.
- Using a Bottle Probe: For the most accurate readings, consider installing a bottle probe. This accessory measures the temperature inside a wine bottle rather than the ambient air, offering greater precision.

Troubleshooting Common Issues
Even with regular maintenance, issues can arise. Here’s how to address some common problems:
-
Blocked Airflow Protection Activated

- For instructions on resetting your unit, see our step-by-step guide: how to reset a wine cooling unit.
-
Power Outage Recovery
- Breezaire units feature power outage protection. After an outage, the unit should resume operation automatically, maintaining your set temperature.
