How do I change temperature - Samsung RB2155SH Bottom Freezer Refrigerator

answer is in instructions
Save-Smart®
Press () to activate the Save-Smart®Function.
1.Set the thermostat to desired temperature using the +/-
buttons (Note: The default Save-Smart®temperature is 72 ? F)
2.When you reach the temperature at which you want to
set the unit, the set temperature will flash several times
and then the display will return to indicate the current
room temperature and will gradually change as the
room temperature changes.
3.When the air temperature is less than the set temperature,
the heater will run in HIGH heat.
4.Once the thermostat reaches the set temperature the heater
will automatically switch to LOW heat to save energy.
5.When the air temperature reaches 4? above the set temperature,
the heater will turn off. The Heater will cycle off and on in the LOW
mode to maintain the set temperature.
All this happens automatically with Lasko Save-Smart®Technology.
To deactivate the Save-Smart®function, press Save-Smart®
again or (hi/lo) for continuous high/low heat.

AUTOMATIC TEMPERATURE CONTROL(Figure 3)
The automatic temperature function will only operate on "High" heat.
You cannot set the temperature automatically when the unit is in the low heat mode.
1.To set the room at a specific temperature press the () or()buttons
to the desired temperature. The display will now reflect the () and the temperature will be flashing. The Heater is now in Auto Temperature Mode.
2.When you reach the temperature at which you want to set the unit, the set temperature will flash several times and then the display will return to indicate the current room temperature and will gradually change as the room temperature changes. NOTE: the temperature display does not indicate the temperature of the heated air being emitted by the heater.
3.Once the room temperature reaches 2 degrees above the set temperature, the Heater will shut off. Once the room temperature reaches 1 degree below the set temperature, the Heater will turn back on and continue to cycle off and on to maintain the set temperature.
4.This function will cancel if the ()button is pressed. The Heater will now be in High heat and run continuously.
NOTE:It is normal for the Heater "fan" to run for approximately 15 seconds when the Heater shuts off after reaching the set temperature.Press the () and() buttons at the same time to change the display to ° Celsius. Press the same two buttons together again to change the display
back to ° Fahrenheit.

Hi its sounds like you have to get the temperature thermostat looked at.

A thermistor is a component whose
resistance changes when its temperature changes.
A thermistor is a special type of resistor whose
resistance decreases as its temperature increases.

A plot of resistance against temperature for
a thermistor is shown above. The plot is unusual
because it shows that a bigger current will flow
at a higher temperature. For most components, the
resistance increases as the temperature increases
and a smaller current flows at a higher temperature.

What is a Thermistor used for?
A thermistor can be used in a circuit to detect a
temperature change. For example, a thermistor may
be used to keep a freezer at the right temperature.
A circuit with a thermistor in it can switch the freezer on if the temperature gets too high and switch the freezer
off again when the correct low temperature is reached.
A thermistor can also be used to trigger a fire alarm. Thermistor are used in all Temperature controlled device and Motors to cut off
circuit when temperature rises over a certain limit to cut off power or trigger another circuit.

If you are referring to the dual white wires with the small white plastic bulb at the end, it's the temperature thermistor. As the temperature goes up and down, the resistance in the thermistor changes as well. The electronic control sends a constant low voltage to the thermistor, and as the temperature/resistance changes, the voltage back to the board changes as well. The board interprets the voltage change, as a temperature change.

What is the complete model number of the unit?

The temperature would charge due to change of cycles in the refrigerator operation. For example, the temperature would slowly rise if the compressor has shut off. Also, the temperature would rise significantly during the defrost process. A heater is activated at the evaporator coil to thaw the ice that forms there. This heat would transfer to the freezer unit and would cause the temperature to go up.

As long as the cycles are constant, and the temperature does not rise significantly and keep rising for a long period, there is no problem.

Oven Temperature Adjustment Option for the MSG5770
If you think the oven should be hotter or cooler, you can adjust
it yourself. To decide how much to change the oven temperature,
set the temperature 25°F higher or lower than the temperature
in your recipe, then bake. The results of the “test” should
give you an idea of how much to adjust the temperature.
To adjust the oven temperature:
1. Press the BAKE pad.
2. Enter 550° by pressing the number pads “5, 5, 0”.
3. Press and hold the BAKE pad for several seconds until 0°
appears in the display.
4. Press any number pad to change the temperature. Each time
a pad is pressed, the temperature changes by 5°F.
• Press repeatedly to reach +35°F. Continue pressing
to reduce the temperature up to -35°F.
• If the oven temperature was previously adjusted, the
change will be displayed. For example, if the oven
temperature was reduced by 15°, the display will
show -15°.
5. When you have made the adjustment, press the
CANCEL pad and the time of day will reappear in the
display. The oven will now bake at the adjusted
temperature.
NOTE: Do not change the temperature setting more than
10° at a time before testing the oven.
It is not necessary to readjust the oven temperature if there
is a power interruption. This adjustment will not affect
broil or clean temperatures.
