2-1) Introduction of main function
●●
A newly Developed SAMSUNG bottom mount freezer in 2008 has the following
characteristics.
Surround Multi Flow
●●
Uniform cooling for each shelf and even in corner in fresh
food compartment by centerpositioned fan and duct with
multiple flow effluences
Twin Cooling System
●●
The refrigerator and the freezer have two evaporators.
Given this independent system, the freezer and the
refrigerator are cooled individually as required and are,
therefore, more efficient.
Food odor from the refrigerator does not affect food in the
freezer due to separate air flow circulation.
Electronic control from outside of Pantry Cover
●●
Adjustable temperature control ((around 41℉(5℃) : Deli /
around 38℉(3℃) : Fresh / around 34℉(1℃) Chilled )
Temperature control from outside of the Pantry : user
friendly design helps keep foods fresh for longer
16" Pizza Corner
●●
Can be used for 16" pizza if stand flip tilting pocket.
Ice and Water Dispenser
●●
The ice and water dispenser provides ice and cold water at
any time.
Secure Auto Close Door System

• Unplug the refrigerator before cleaning and making repairs.
• Remove any foreign matter or dust from the power plug pins.
- Otherwise there is a risk of fire.
• Do not use a cord that shows cracks or abrasion damage along its length or at either end.
• Do not plug several appliances into the same multiple power board. The refrigerator should always be
plugged into its own individual electrical which has a voltage rating that matched the rating plate.
- This provides the best performance and also prevents overloading house wiring circuits, which could
cause a fire hazard from overheated wires.
• Do not install the refrigerator in a damp place or place where it may come in contact with water.
- Deteriorated insulation of electrical parts may cause an electric shock or fire.
• The refrigerator must be grounded.
- You must ground the refrigerator to prevent any power leakages or electric shocks caused by current
leakage from the refrigerator.
• Do not put bottles or glass containers in the freezer.
- When the contents freeze, the glass may break and cause personal injury.
• Do not store volatile or flammable substances in the refrigerator.
- The storage of benzene, thinner, alcohol, ether, LP gas and other such products may cause
explosions.

However, It means that micom signal is outputting, it does not mean whether load is operating or not. That is to
say that though load operation is displayed, load could not be operated by actual load error or PCB relay error
etc. (This function would be applied at A/S.)

● If the display changes to option setting mode, all displays will be off except freezer and
fridge compartments temperature display as below.
(Fresh food and freezer compartments case will be explained only because all options
are operated with the same method according to the option table.)
1) For example, if you want to change freezer compartment standard temperature to 28.4℉(-
2°C) by operating option, do as below.
This function is for changing the standard temperature.
In -2℉(-19°C) of current temperature of freezer compartment, if you make the temperature
lower to 28.4℉(-2°C) by the option, the standard temperature would be controlled -6℉(-21°C)
Therefore, if you change the setting of temperature option to -2℉(-19°C) on the panel, the
appliance will be operated with -6℉(-21°C).
It means that standard temperature is controlled 28.4℉(-2°C) less than setting temperature in
the display.
Basically, option function has cleared data at shipping process.
Therefore, almost all setting value are "0".
NOTE
Check the product information manual or specifications because setting value could be
changed particularly for the purpose of improving product at mass producing process.

2) After changing to the option mode, fresh food compartment "0" , freezer compartment
"0" will be displayed. ( Basically fresh food compartment "0", freezer "0" would be set at
shipping process, but setting value could be changed for the purpose of improving
product at mass producing process.)
- If fresh food compartment "0" shows only, temperature reference value of freezer
compartment will be set and current freezer compartment temperature code will be
displayed on the freezer temperature display.
3) If freezer compartment "4" is set as below freezer compartment code after fresh food
compartment "0 is set, standard temperature of freezer compartment will be lower than
28.4℉(-2.0°C).
(Refer to the picture "changing the freezer compartment temperature")
: If you wait for 20 seconds after completing the setting, MICOM will save the setting value
to the EEPROM and normal display will be returned and the option setting mode will be
canceled.
4) Option changing method as above is the same as all RF266/265** model.
5) By the same method as above, it is possible to control the fresh food compartment
temperature, water supply, ice-maker harvest temperature/time, defrost return time,
hysteresis by temperature, notch gap by temperature etc.
6) Option function is set in the EEPROM at shipping process in the factory.
You would better not to change the option of your own.
Completing the setting is that option function return to normal display after 20 seconds.
Do not turn off the appliance before returning to the normal display mode.
Option setting function exists in the other items.
We will skip the explanation of the other functions by the option because it is
NOTE
associated with refrigerator control function and is not needed at SERVICE.
(Please do not set the other options except above SERVICE Manual.)

1. When you replace the lamp of freezer, please power OFF to avoid an electric shock.
2. Please keep in mind you could get burnt by the excessive heating of an incandescent light bulb.
3. Bimetal is installed in the refrigerator LAMP. Check that if LAMP may be OFF by bimetal.
