Refrigerator makes a gurgling or hissing sound periodically.

Information: Gurgling, hissing, or gentle popping sounds are usually normal as refrigerant flows and defrost water evaporates.

Steps:

• 1. Verify operation: If cooling performance is normal and there are no leaks, these sounds are typically not a fault.
• 2. Check for leaks: If you notice oil stains or a strong chemical smell, unplug the unit and contact a technician.
