Where is the condensation drain tube located?

Lois,
I am not sure if you have resolved this problem yet or not, but hopefully this article might help. It does not sound like all refrigerators have a drain tube, but they might have a drain channel. They may also have the water flow down the refrigerator back wall to the bottom of the refrigerator and a drain hole may exist under a pullout storage area. Good Luck and I hope this was helpful. I am sorry I do not have specific information on your model.
