The problem is the drain is clogged. Remove the back panel in your freezer and at the bottom of the evaporator coil you will see a hole about ½” in diameter this is the drain tube. You might need to use some warm water to melt the ice and then run a wire being very careful not to puncture the hose and run it down the tube to free up the drain. This tube travel down to the bottom of your refrigerator to a pan sometimes located on top of the compressor or somewhere else down there. It collects the water there to evaporate. You can enter your model # at www.appliancehelponline.com for a diagram or illustration of your refrigerator. Not all models are available.

Open both doors and check to see if the center divide between the the freezer and fridge is warm/hot to touch. If so, you need a new cooling motor/fan. Motor should come with new fan and can be purchased for around $60. Pretty easy to change yourself. In cover on back/bottom of unit. Have exact model and changed that part 6 months ago.
