I have had this refrigerator for about a year, The freezer get froze up and the temp in the frig. goes up ( not Cooling). I have to manually defrost . I replaced the defrost heater and the defrost thermostat but this did not cure the problem. Do I need to replace the motherboard , and does the motherboard( main control board ) control the defrost timing.

The problem could be in the encoder control that is in the fridge section or the mother board.

The encoder is number 424 on the fresh food section breakdown.
