Is it leaking from the freezer side? If so it's possible your drain tube is iced over. Pull out the bottom bin and look for ice build up coming from the back side. If so you need to melt the drain. I'm not sure if you need to open the back panel on this model to get to it but if so it's not hard to do just a few screws. Once you access the drain use hot water to melt the drain out till it run's free, I use a turkey baister for this, but whatever works for you. There will be an excess of water in the drain pan under the fridge so be ready for it with a towel. I then mix a little baking soda and hot water and run it through to clean and help aleviate the problem in the future.
