Freezer makes gurgling or hissing sounds periodically

Safety first: These sounds are typically normal and do not require repair.

• Identify pattern: Gurgling or hissing shortly after the compressor starts or stops is usually normal refrigerant movement.
• Check performance: If temperatures are normal and no error codes are present, no action is needed.
• Inspect for leaks (if odor present): If you smell a chemical odor or see oily residue, unplug the unit and contact a technician to check for a refrigerant leak.
