CHECK THE INSTALLATION STATUS
■ If the display changes to option setting mode, all displays will be off except freezer and fridge compartments temperature
display as below.(Fridge 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 -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 -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 -4℉(-2°C) less than setting temperature in the display.
Basically, all the data in option has cleared from the factory.Therefore, almost all setting value are "0".But, some setting
values could be changed for the purpose of improving performmance.NOTE You need to check the product manual and/or
specification.
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 -4℉(-2.0°C).
