Freezer makes a gurgling or hissing sound periodically; cooling seems normal.

Note: Soft gurgling, hissing, or whooshing sounds are usually normal in modern freezers.

• Verify performance: Check that the freezer maintains the correct temperature and there are no error codes or leaks.
• Check installation: Ensure the cabinet is level and not amplifying normal sounds through contact with cabinets or walls.

If noises are very loud, metallic, or accompanied by poor cooling, have a technician inspect the sealed system.
