I found a manual, although I cannot be sure it is for your exact model, it is located HERE
. This is what is stated under "Temperature Adjustment"
IF TEMPERATURE DISPLAYS FLASH...
If ever you see both temperature displays continously flashing,
it may indicate that the control system has detected a
performance problem. Call your service representative, who
can interpret the flashing message.
To maintain temperatures, a fan circulates air in the refrigerator
and freezer compartments. For good circulation, do not block
cold air vents with food items.
This is located under "Turning the Cooling System On and Off"
TURNING THE COOLING SYSTEM ON AND OFF
You can disable the cooling system in your refrigerator by pressing the On/Off button located on the left side of the temperature
control panel. To ensure that you do not accidentally turn off the cooling system, the button does not work unless you press and
hold it for three seconds. Once you disable the cooling system, all refrigeration to the freezer and fresh food compartments stops.
To turn the cooling system back on, you must again press and hold the On/Off button for three more seconds.
If the manual I selected is not the one for your particular machine, there are others located HERE
. There are various ones only differing by a "upgrade" letter on the end, perhaps for different models of different manufacturers, produced by the same company.
I hope this is of some help
