This information applies specifically to the Samsung RS21 range of Fridge Freezers. These are the most popular of the Samsung range of Side-by-Side fridge freezers currently in use in the UK today.
The RS21 range of models have a common fault symptom affecting the fridge section only. If, like many other owners of this model, you are finding that the fridge is getting too warm, just follow these simple directions and within seconds you will know the cause of this fault.
All models of Samsung Fridge Freezers including the RS21 range, have a clever self diagnosis facility built into the control module of each appliance. This self diagnosis facility is easily accessed by making use of the control panel on the front of the freezer door. This panel consists of four buttons and two separate digital temperature displays (one showing the temperature of the freezer compartment and the other showing the temperature of the fridge compartment).
Press the two top buttons of the control panel, holding them both down together for eight seconds. After the eight seconds, you will hear a regular ‘pinging’ sound. Keep holding the two buttons for one more second, and then release both buttons.
Now look carefully at the digital fridge temperature display (the right-hand pair of numbers) which is immediately below the two buttons that were being pressed. If there is a fault with the fridge section, you will see that one of the lines (that would normally make up the number on the display) is flashing. As an example of this, if the lowest horizontal one is flashing, it is indicating that the fridge fan motor has failed.
The fault mentioned above is probably the most common one that occurs, and the fault can be easily and safely repaired yourself without the need of an engineer. Spare parts for these Samsung models are available at reasonable prices. If you find that a different line is flashing on the digital temperature display, it will mean that there is a different cause of the fault.
If instead the freezer is faulty, one of lines of the digital temperature display for the freezer (the left-hand pair of numbers) will be flashing. Again, each specific line of the freezer digital temperature display represents a different freezer fault.
Please note that whenever the fridge freezer has been unplugged from the electrical power supply, the self diagnosis information, discussed above, will be deleted. Don’t worry though, just plug it in again and wait for the fault to show itself again. This usually happens within about twelve hours.
Whenever you do this test, after a short time (about thirty seconds) the control panel will automatically come out of this self diagnosis mode and go back to the normal operation mode.
