Per cuffs' advice in the post above mine, the drain hole is behind the crisper in the fridge section. I'm not familiar with your model, so why there's a drain in the fridge, I don't know. All fridges I've ever owned have had the evaporator at bottom rear in the freezer section, and drain directly below.
I'm sure there's an exploded view of your fridge's interior and mechanical components on line somewhere if literature that came with your fridge doesn't provide one. That should help you zero in on where the drain is located.
