Freezer makes gurgling, hissing, or popping sounds during operation.

Safety: No repair is usually required.

Explanation and checks:

• Normal operation: Gurgling and hissing are typically normal sounds of refrigerant and defrost cycles.
• Verify performance: If temperatures are normal and there are no leaks or odors, no action is needed.
• Secure loose parts: If noises are excessively loud, check for loose panels or tubing and secure them.
