If your Samsung refrigerator icing up then you need to check if there is any leak. Pour some drops of water into the dispenser bucket in the refrigerator door.
Without shutting its door, have a look at the dispenser on the outside. If water is pouring out, then there surely is a leak.
To be double sure, put a torch under the ice maker. There surely is a leak if you can see the light from your torch in the ice makers. The leak is the right basis for freezing. Warm or moist air causes a frost buildup. And if water isn't draining the right way, it will then freeze with time. It means you will have to replace the ice maker.
The leak may mean water or air is at this moment coming out of some opening somewhere. It may also mean water isn't draining properly. You will have to use the silicone material to seal the left and back area where the ice maker fits. This is, you will have to remove the ice maker to complete this checkup.
You may use another solution to replace the circuit board and change the unit's firmware that is given next. This isn't something you can do all by yourself. You will have to contact the Samsung help center for this. The reason is that the ice maker freezing up may be a common issue with Samsung refrigerators. If your warranty is still on, then you won't have to pay for repairs.
Solutions for Samsung refrigerator icing up but not cooling:
The Samsung refrigerator ice machine icing up is a common issue, and the following are a few things you can check:
1. Door seals:
Check the door seals or the gaskets to be sure that they latch well. Also, make sure that they are clean. If the door isn't closing well, humid air will enter the refrigerator and cause a frost buildup. But still, this will reduce the cooling strength of the whole unit.
2. Ice dispenser flap:
Also, be sure that the ice dispenser flap closes all well. If it doesn't, it may keep the door from shutting up properly so outside air will then enter and build the frost. Check if ice or debris is keeping it from flushing with its housing, and then remove it.
Samsung refrigerator coils freezing up
If your Samsung refrigerator evaporator coils ice up, defrost them by hand by turning the refrigerator off for 24 hours at least or using hot water. But this also tells you to check some parts of the refrigerator.
Check the defrost heater that is under evaporator coils. If the heater is finely working, it must defrost the ice buildup on coils. But if it's not working, it is either defective, or the timer on defrost is bad and stuck only on the cooling mode. Test the heater or timer using a multimeter to check for continuity. If there isn't any of it in both of them, you will have to change them.
