It could be a [product|IF476-422|defrost thermostat|new_window=true] problem or a control board problem.
I included the control board as a possible problem because looking at the [document|32553|tech sheet] for the model the auto defrost cycle occurs after a ''minimum'' ''of 8 hours of compressor run time''. You said that it stops after only ~6 hours. This makes me think that it is not stopping for a defrost cycle. The only other reason that it would normally stop is when the temperatures in the compartment were both at the lower limit of their preset temperature range and therefore no further cooling was required until the temps rose again.
The actual amount of time that the compressor takes to achieve the 8 hours run time may take longer than a straight 8 hours of elapsed time. This depends on such factors as the ambient temp and how many times the doors have been opened due to normal usage e.g. overnight it is cooler and the doors would be opened less often than during the day so less warmer air would have entered the compartments (when the doors were open - or less cooler air lost if you prefer) requiring the compressor to run less often and for shorter periods to cool it back down to the set temps.
Just to eliminate the possibility perhaps check if the temp sensors in both compartments test OK (as per the diagnostics as shown in the tech sheet). The sensors indicate that the correct temp has been reached so the compressor would be turned off. Although it should be turned on again when the temp rises above the upper preset limit.
Looking at the tech sheet the defrost thermostat only opens the defrost heater circuit when (or if) the temp near the evaporator unit exceeds its operating temperature, but in doing this it may also signal the control board to end the defrost cycle. I'm not 100% sure of this but maybe it is worth checking if the defrost thermostat is OK
