We have a walk-in refer that shares a wall with our walk-in freezer. At the base of the wall of the freezer, on the refer side there's a formation of ice that runs the full length of the wall. These walk-ns are set on solid concrete, with ceramic tile flooring. Although i'm not very familiar with walk-ins, I can only guess that there is a warm/room temp air leak somewhere in that joint. My questions are; 1.) What would be the easiest/quickest way to locate the leak, without shutting down either or both of the two boxes? And; 2.) Why would it freeze on the refer side, but not on the freezer side?
Thanks for your input.
