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

Safety: Unplug the freezer before adjusting internal components or accessing the rear.

• Level the appliance: Use a spirit level and adjust the front feet so the freezer is stable and does not rock.
• Check compressor mounts: Access the rear and gently move the compressor. Tighten or replace rubber mounts if excessively loose.
• Inspect refrigerant lines: Look for copper tubes touching each other or the cabinet. Gently bend them apart slightly to prevent contact, taking care not to kink or crack them.
• Secure panels and fan: Inside the freezer, ensure the fan shroud and inner panels are firmly screwed in place. Tighten any loose screws.
