Wine cooler makes a gurgling or hissing sound periodically.

Safety: No repair is usually required. Do not attempt to puncture or modify the sealed system.

Steps:

• 1. Identify the sound: Soft gurgling, hissing, or trickling sounds when the compressor starts or stops are typically normal for Kalamera wine coolers.
• 2. Check for performance issues: If the cooler maintains proper temperature and there are no error codes, these sounds are likely normal operation.
• 3. Reduce resonance: Ensure the cooler is level and not touching cabinets or walls that can amplify normal sounds.
• 4. Monitor over time: If the noise becomes significantly louder or is accompanied by loss of cooling, contact a technician to inspect the sealed system.
