Freezer makes loud knocking, rattling, or banging noises during operation

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

Steps:

• Level the appliance: Adjust the front feet so the freezer is stable and does not rock.
• Check baskets and shelves: Ensure all are seated properly and not vibrating against each other.
• Inspect compressor mounts: At the rear, verify the rubber grommets under the compressor are intact. Replace if hardened or missing.
• Secure tubing: Gently bend any copper lines that are touching each other or the cabinet, adding foam sleeves if necessary.
• Evaporator fan noise: If noise comes from inside, access the fan and check for play in the shaft. Replace the fan motor if bearings are worn.
