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

Safety first: Unplug the appliance before tightening any components near electrical parts or moving fans.

Level the fridge:

• Use a spirit level on the top of the appliance.
• Adjust the front leveling feet until the unit is stable and does not rock.

Check rear components:

• Remove the rear lower panel.
• Ensure the compressor mounting bolts or rubber grommets are intact and tight.
• Inspect the condenser fan (if fitted) for contact with wires or debris; clear obstructions.

Internal noises:

• Inside the fridge and freezer, ensure shelves and drawers are seated properly and not vibrating against the liner.
• Tighten any loose interior panels or covers.

Normal sounds: Some gurgling or clicking is normal as refrigerant flows and the defrost system operates. Focus on persistent loud knocking or rattling as abnormal.
