Kitchenaid model ksc24c8eyy02, side-by-side a little less than six years old.
Water pooling under crisper drawers found to be caused by a rusty galvanized steel drip pan (part number W10317862). The drip pan rusted so bad the rust bits clogged the drain pipe that drains condensate from the lower evaporator to the underside of the fridge.
This was fixed by making a homemade drip pan from aluminum and cleaning out the drain. I am going to order a new drip tube so the next time I have the fridge pulled out, I can replace it. Also, found out you need to look at parts diagrams from the Sears site. The drip pan was not shown on at least one other site that I spent a lot of time on.Video
