The fridge temperature is normally set to 5C and my thermometer shows it around this temperature, but now it is showing 7-8C and setting the fridge temperature lower has no effect. The temperature of the freezer (below) is correct.
1-The condenser coils are usually located under the refrigerator. They dissipate heat as refrigerant passes through them. If the condenser coils are dirty, they won't dissipate the heat effectively. As debris builds up on the coils, the refrigerator becomes less efficient, causing the refrigerator to work harder to cool down. If the coils are significantly dirty, the refrigerator will not be able to maintain the proper temperature. Check the condenser coils to determine if they are dirty-if the condenser coils are dirty, clean them.
2-The evaporator fan motor draws air over the evaporator (cooling) coils and circulates it throughout the refrigerator and freezer compartments. Some refrigerators have more than one evaporator fan motor. On refrigerators with only one evaporator, the evaporator is located in the freezer compartment. If the evaporator fan is not working, it will not circulate the cold air to the refrigerator compartment. If this occurs, the freezer may still get cold, while the refrigerator will not get cold. To determine if the evaporator fan motor is defective, try turning the fan blade by hand. If the fan blade does not turn freely, replace the fan motor. Additionally, if the motor is unusually noisy, replace it. Finally, if the motor does not run at all, use a multimeter to test the motor windings for continuity. If the windings do not have continuity, replace the evaporator fan motor.

If the fridge has been making more noise than usual, like the sound of a plastic fan grating against something then the fan has probably seized up with ice. This will cause the fridge temperature to rise. It is located at the back of the fridge behind a plastic panel at the bottom where the water cooler pipe and bottle are. You need to partially remove this panel just enough to be able to aim a hairdryer down the back of it to defrost the fan.

Is the back of the freezer section iced up?
If so you could have a defrost problem. All the cooling components are in the freezer section there is a damper controlled by a dial in the refrigerator that opens and closes.
If the damper is closed it will not allow air into refrigerator section. It is seperate from the Thermostat.
If the damer is opened to much you can start freezing food in the refrigerator section.
If there is ice on the back wall of the freezer section. It is not defrosting. There are 3 parts in the defrost process. The thermination stat, the heater, and the defrost timer or it's a timer on the electronic board behind the metal plate on the back of the refrigerator.
Good Luck

Ring samsung up because this is a common fault in that make. I had the same problem, They should do something depending on when it was purchased ( 2005-2006 i think it was) it was on watchdog.

Hello, The answer to these questions lies in the way the
freezer/fridge combo works. The freezer is where the cooling coils are located.
Then air is moved over the coils and circulated through the fridge side by a
small blower or fan. The problem arises when the air is not circulated for some
reason.

The reasons the air is not moving is usually two reasons
The first reason is pretty simple to fix, you simply replace the air circulator
and things are good again.
The second reason can be more difficult.
1. The timing device that runs the defrost cycle of the refrigerator is
defective.
2. The heater coil that melts the water is shorted or not working
Usually the first thing to check is the heater coil. If there is resistance
through the coil then most likely it is still good.
The timing device can be an advanced defrost control board or a mechanical
timing device.
If the heater coil checks out to be good then the problem should be the timer.
For most situations, unplugging the refrigerator and allowing it to defrost on
it's own will get you going temporarily, till parts can be shipped to you. That
will melt the ice and give you a few days or a couple of weeks till it ices up
to the point where it will not work again.
So you can see here, the problem can usually be traced to one of three things.
By methodically checking these parts you can isolate
your problem and fix it.
Take care.
