A lot of times freezing in the refrigerator part is due to a couple of things. One being lack of air movement, folks will add a 12v fan to move the air around which keeps a more even temp. The other is where is the "thermistor" located on the fin? It should be on the second or third fin, the closer to the top of the fin the colder your frig will be and the closer to the bottom the warmer.
