Refrigerator

For the past week, I have been finding water in my refrigerator. I have a freezer on top refrigerator - no water/ice in the door - just your plain jane run of the mill refrigerator. The settings were off a bit - freezer too cold - refrigerator too warm - touched by little hands I'm sure. But we fixed that and mopped up the water. However, there is still water accumulating on the top shelf. The amount of water is significantly less now, but still requires a paper towel or two every day. Yesterday Mike pulled the refrigerator out and vacuumed behind and underneath. This evening I though I would tackle the inside of both refrigerator and freezer. Any other ideas????
