Freezer making loud humming, buzzing, or rattling noises during operation

Safety first: Unplug the freezer before touching moving parts or metal tubing.

Steps:

• 1. Identify noise source: Listen at the back, sides, and inside to locate where the noise is loudest.
• 2. Check leveling: Ensure the freezer is level and all feet are firmly on the floor. Adjust leveling feet as needed.
• 3. Inspect compressor mounts: At the rear, verify that rubber grommets under the compressor are intact. Replace if hardened or missing.
• 4. Secure tubing: Gently move refrigerant lines and condenser to ensure they are not touching the cabinet. Use foam pads or clips to prevent contact.
• 5. Fan inspection: Access the evaporator fan and check for ice or debris hitting the blades. Defrost and clean as necessary.
