My freezer section was icing up to the point that it couldn’t maintain below 40. I realized that my keg box was just wayyyy too big for a mini fridge so I got some of the pink thick foam and a wooden frame and basically filled in about half of the keg box. Now it can hold either 2 1/6kegs or 1, half keg, plus CO2. I had to struggle with this so hopefully this saves someone time in figuring out how to fix a similar problem.
