I was having the same problem and found that the drain hole on the freezer side at the bottom was clogged. When the condensation drips it should drain through that hole. Since it is clogged the water builds up and leaks out the side of the refrigerator. Here is how to fix it:
1. Check to make sure you see the hole and that it is clogged. You will know it is clogged if water simply sits on top of the hole and doesn't drain through it.
2. Unplug the refrigerator and get a flashlight - I used the little cute one on my key chail :-)
3. Go to the back at the bottom right and remove the vent cover. It is just a few screws.
4.On the right you will see a plastic pipe that connects to the rain drain inside the freezer.
4. Simply disconnect the pipe and remove it. The pipe is bendable so do be afraid to bend it if you need to in order to remove it.
5. Clean out the pipe with hot water. You will need to tap it in the sink to make sure all the "gook" is coming out. I boiled hot water and poured it through the pipe until the water flowed through both ends completely.
5. Re attach the pipe and screw the vent back on.
You have solved the problem!
I bought this refrigerator new in 1998 and it has been a great investment. This is the only problem I've ever had. I'm happy this was an easy fix.
It took me more time to find a fix on the internet than it did to actually fix it. So that's why I'm sharing the solution with you. I hope this is helpful!
