Unit makes a gurgling or hissing sound periodically.

This is usually normal operation.

• Identify the sound: Soft gurgling or hissing when the compressor starts or stops is typical for hOmeLabs wine coolers.
• Check for abnormal signs: As long as cooling performance is normal and there is no strong odor or visible leak, no repair is needed.
• Reduce resonance: Ensure the unit is level and not touching cabinets or walls that can amplify normal sounds.
