I had pretty good luck after I finally found the drain system. I had to purchase a do it yourself book form Sears to find it. Take out the bottom of the freezer section--two screws in the front of the bottom of the freezer compartment. Then mine was really iced up. I used a hair dryer and removed all the ice and finally got down to the drain pan that should probably be called a drain trough. It's in the very back at the bottom.
I kept sponging up the water and blasting awy with the hair dryer until it seemed to free up and the water remaining in the drain hole went down. We'll see if it happens again.
