Check your gasket around the fridge door. If it isn't sealing properly moist air from cooking and showering will enter and collect on the cooling fins. Insert a sheet of paper and see if you can pull it out. Move the paper all around the gasket and try again after each relocation. If you narrow it down to an area less than the size of the paper, switch to a $1 bill (any denomination actually) to further zero in on the gap between the gasket and frame. This is usually the culprit.
