I am having trouble with a small Keezer I am using. It is a small Kenmore 5cf freezer with an eight inch tall collar with 2 foam insulation. I have it set up to hold four corny kegs and a basket. The keezer keeps very good temp with the compressor hardly running at all. The temp near the top of the Keezer regulates between 41 and 43, while down in the bottom, the temp hovers right at 38. My problem is that the kegs on the step tend to completely freeze up and it is driving me a bit crazy. To me, the temps dont seem that low and I dont really want to run it with the temps that much higher, but I may not have much of a choice here. Anyone care to attempt explanations here?
