Are you measuring air temperature in the kegerator or the actual beer temperature when you say that it's too cold? Can you see the thermostat probe or does it appear to be inserted into the evaporator coil?
The reason for these questions is that TRUE commercial coolers use a thermostat that monitors the actual evaporator coil temperature during operation. The evaporator is allowed to drop to well below freezing during the cooling cycle. Once the evaporator set
temperature is reached, the compressor is cycled off until the probe reads a fixed
temperature above freezing and then the cycle begins again. This scheme is used in order to allow the evaporator to defrost for each cycle. You can not use air temperature to determine set temperature, actual beer temperature must be used. The resulting beer temperature is basically an average of the set and fixed temperature.
I would suspect that TRUE kegerators operate the same way.
