Freezer makes a gurgling or hissing sound periodically, even when the compressor cycles.

Safety first: No repair is usually required for mild gurgling or hissing sounds that occur during normal operation.

Step-by-step checks:

• 1. Identify sound source: Listen carefully; if the sound comes from inside the cabinet or rear tubing and is not accompanied by performance issues, it is likely normal.
• 2. Monitor performance: Ensure the freezer maintains correct temperature and no error codes are displayed.
• 3. Check installation: Make sure the freezer is level and not touching other objects that could amplify normal sounds.

When to call a technician: If gurgling is very loud, continuous, or accompanied by poor cooling or error codes, have a technician check the sealed system.
