Refrigerator runs but makes a gurgling or hissing sound inside walls

Safety: No repair is usually required for these sounds.

Information:

• 1. Normal operation: Gurgling, hissing, and occasional popping sounds are often normal as refrigerant flows and components expand/contract.
• 2. Monitor performance: As long as temperatures are correct and no error codes or leaks are present, these sounds can be considered normal.
• 3. Reduce resonance: Ensure the refrigerator is level and not touching cabinets that can amplify sounds.

Note: If noises are accompanied by loss of cooling or strong odors, seek professional service.
