Refrigerator makes a gurgling or hissing sound periodically.

Information: Gurgling, hissing, and occasional popping sounds are often normal in modern Gaggenau refrigerators, especially during and after compressor operation.

Steps:

• 1. Verify cooling: If temperatures are normal and there are no error codes or leaks, these sounds are likely normal.
• 2. Check installation: Ensure the refrigerator is level and not touching cabinets or walls, which can amplify normal noises.

Action: No repair is typically required unless noises are extremely loud or accompanied by performance issues, in which case have a technician inspect the unit.
