Freezer makes a loud rattling or banging noise when running.

Safety: Unplug the freezer before adjusting internal components.

Steps:

• Level the unit: Adjust the front leveling feet so the freezer is stable and does not rock when pushed.
• Check interior: Ensure baskets and shelves are seated properly and not rattling. Move items away from the walls.
• Inspect evaporator fan housing: Remove the rear interior panel and tighten any loose screws on the fan shroud or evaporator brackets.
• Secure tubing: From the rear, gently reposition any refrigerant lines that are touching the cabinet and secure with foam or clips where appropriate. Do not kink or sharply bend tubing.
