Water is leaking and freezing on the top two selves near the rear on the refrigerator. My unit of about 10 years old and just has the freezer on the top and the refrigerator on the top. No signs of leaking anywhere else. Both the refrigerator and freezer are still cold.

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. Try using a turkey baster to flush out 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. After cleaning mix a 50 -50 solution of baking soda and water and run some down the drain tube this should help prevent future clogs.
