I have been seeing water accumulate under the crispers in the refrigerator. After doing a number of searches, I came to the conclusion that the freezer drain is plugged. I tried to access the drain hole by taking the back panel out of the freezer, but can't figure out how to do it. I have removed the screw in the upper right, released the 2 clips at the top, but the panel stays put. There seems to be something on the left side that is holding it, but I don' see any more screws or clips and I am afraid of pulling too hard and breaking something. I was able to get a piece of tubing to the drain and siphon some water out but not enough to free the clog. Any help would be greatly appreciated.
