Refrigerator Leaking From Icemaker
If it's leaking from inside the freezer then it's coming from the icemaker or the drain. Lets start with the icemaker. If it's the icemaker there will likely be an ice hanging from the icemaker or just a big block of ice in the ice bin. In any case, it will be obvious.
There are a few reasons this will happen: one is the icemaker will stop turning when it gets to the fill cycle. This will happen when the gears in the icemaker break. On GE icemakers that were made before the year 2000, you can see the gears by taking off the cover on the front of the icemaker. However, if the small gear is broke you can't buy it as far as I know. I have been taking them off of junk icemakers for years. So this part may be hard to find. But if the big gear is broke replace it. Another reason icemakers leak is the fill tube is stopped up and I already discussed this earlier (replace water valve and clean out tube).
Another reason icemakers leak is that the water comes in too fast so it over fills the first cube mold. When this happens you will get a few drops of water when it fills. To fix this you have to take the icemaker out and remove the piece on the side of the icemaker. I don't know the name of it so for this we'll call it cube separator because that's what it does (most of them just snap off others have a screws). Now take silicone (RTV) and put a small amount around the first cube mold only under the cube separator. Now reinstall the cube separator and wipe off excess silicone and it shouldn't leak anymore.
Another reason that icemakers leak is that the refrigerator water valve sticks after the icemaker goes out of the fill cycle. When this happens the valve stays on and the icemaker keeps on turning, in which case, replace the refrigerator water valve.
