The defrost is not working,.The evaporator coil in the inner section of freezer is got blocked by ice .
Try manual defrost reset procedure: ----
First unplug the unit from main power outlet. Then empty whole unit completely. Then keep both the doors open. Wait for 24 hours. All the ice collected on the coils and in the freezer section will get melted. Clean the water from the sections. Then Connect the power cord of the unit to main power outlet after 24 hours/.Then set the temperature to normal in both fridge and freezer section. It will take near to 4 hours to get run in its proper cooling cycle. Then check, if the problem returns again. If the same problem occurs then it's defrost problem. The defrost board and the defrost thermostat/heater is not functioning properly and it has to be checked and replaced.
Check the damper if there is too much water collected in the damper then press the damper and remove the water collected in it. The procedure of this unit is as follows: --- The compressor starts then it cools the freezer section. When the freezer reaches its cooling level the defrost cycle starts functioning. In this cycle the fan in the freezer section starts running and the cool air in the freezer section is passed to the refrigerator section and the refrigerator section gets cold. The air from freezer to refrigerator passes from the section, in that section the damper is located. Now this problem which you mentioned. In this problem the freezer works but no cooling in fridge, this happens if the thermostat is not functioning or the heater is not heating. Then the ice starts getting collected on the evaporator coil. The evaporator coil is at the internal section of freezer. If too much ice gets
collected then this ice blocks the fan in the freezer section from functioning and this blocks the damper section with ice getting collected there. This all procedure is controlled by the main defrost board of the unit. Now if the damper is not got blocked with too much water or if the ice is not got collected on the damper area then check the evaporator coils. If there is too much ice got collected on the coils, then takes a hair dryer and melt the collected ice. Then see if the problem returns again. But if there is little bit ice collected on the coils and fan is running properly then it's not a problem. In that case main defrost board is faulty and it has to be replaced. The main defrost board is working but its not controlling the functions as required so the freezer works but fridge section not getting cold..
