I purchased a severely modified Beverage Air BM23 recently. It seems to me that the whole cooling apparatus was switched out with parts from a compact refrigerator. There is now an evaporator plate screwed into the back of the inside. When I first bought this thing, I did get a bit of ice on the evaporator, so I know it was getting cold enough. Now, the evaporator itself will only get down to around 40 degrees on it's surface, and the compressor has to run continuously to do that. My kegs are only getting to around 45 degrees.
Anyone have any suggestions? I really hate to put more money into this thing if it's not worth it.
