Freezer makes gurgling, hissing, or dripping sounds periodically, especially after the compressor stops.

Safety first: No disassembly is usually required. Do not puncture or bend refrigerant lines.

Steps:

• Identify pattern: Gurgling and hissing immediately after compressor shutoff are typically normal refrigerant equalization sounds.
• Check drain pan: Light dripping into the drain pan during or after defrost is normal. Ensure the pan is properly seated and not touching other parts that could amplify noise.
• Secure loose parts: If noises are excessively loud, check that panels and tubing are secure and not vibrating against the cabinet.

Note: These sounds are generally normal for Insignia freezers and do not indicate a fault unless accompanied by cooling issues.
