Fluctuating temperature

Question

Danby DAR604wIntermittently the refrigerator that is set at 41 will suddenly go down to 32degrees. This is strictly a beverage refrigerator for us and as such can be quite a mess as bottles break. This has happened 3 times in the year since we purchased it. The first time we considered it a fluke, but it has happened 3 times without us touching a control panel. What is wrong with this?
