Switch the fridge off a day in advance, empty it and let the freezer defrost. Dry everything well and tape the door shut, or leave it ajar if it will be in transit for longer.
Preferably transport the fridge upright. Take out loose shelves and drawers and pack them separately. In your new home, let it stand for a while before you switch it on. Check the manual to see how long that should be for your model.
