The fridge part of the refrigerator works, but the freezer has stopped and is not cool at all. For the past week or so the refrigerator has also been leaking water onto the floor and it was making a rattling noise for a few hours, which seemed to come from a motor or fan on inside the fridge near the panel where the temperature control setting is located (it has since stopped making that noise - we turned the temperature setting down a little). Ice had also built up on the ceiling of the fridge part, which has been melting last few days.
I cleaned the coils on the back as best I could.
