the bottom of Fridge under the pantry drawer has constant water that ends up freezing.  I had my repair guys clean everything, check for water line leaks etc., then he suggested to replace the Refrigerator side evaporator panel.  When we opened that up, we could see where the leak was coming from.  the back wall and when you pushed on the back wall near the screw holes, you could see water come out from them so the issue is inside the wall of the fridge - probably the insulation and you can't remove the back of the refrigerator to back inside the insulation - at least not without cutting it open.  So this appears to be a manufacturer issue?
