Check the hole under the evaparator, it could be pluged with ice or other particals. also make sure the the drain cup or elbow leading to the outside of the unit is not pluged.
Try pouring boiling (or at least very hot) water down ... back of the fridge on top of the compressor.
If the refrigerator is equipped with a water dispenser on the freezer door, check if the water line to the dispenser is leaking. Also, check the drip pan to be sure it isn't out of place, broken or cracked.
Inside back wall of refrigerator:In some refrigerators, the water from the defrost cycle is intentionally directed down the back wall of the refrigerator, where it then flows to the bottom of the refrigerator compartment and out to a small drain - usually located beneath one of the drawers at the bottom of the refrigerator. If the drain becomes clogged or blocked, the water may back up. To fix this problem, clear the obstruction.
Self-defrosting refrigerators usually dispose of the water generated during the defrost cycle via a tube or channel that directs the water to a pan at the bottom of the refrigerator. From the pan, the water normally evaporates. (See a more detailed explanation of this in the How Things Work section of our website).
If the tube or channel is clogged or obstructed, the water backs up and leaks into the inside of the refrigerator compartment. Then the water builds up at the bottom, inside of the refrigerator. When the water has built up for a time it may spill out of the front of the door opening. To fix this problem, clear the drain tube or channel and allow the defrost water to flow down to the drain pan.

Another cause may be the following. The refrigerator may have doorframe heaters to evaporate any condensation on the cabinet frame. If your refrigerator is equipped with a switch inside that says "energy saver" or something similar, while running in that mode the door heaters are disabled. Turn the switch to the opposite setting and wait 24 hours. If the condensation disappears the problem is solved.
