TROUBLE SHOOTING
When the display is converted to Option Setting mode, the entire display is to be turned off except the
Fridge & Freezer 7-SEG LEDs as follows.
Option Value
1) The following shows the way to shift the Freezer temperature by -3 This function is to shift its base
temperature. For example, if the current base temperature is -18 and it is lowered by -3
Option Setting function, the unit is to be controlled based on -21°
on the display panel after shifting the base temperature, it is to be controlled based on -21 So,
when the base temperature is lowered by -3 , the unit is controlled -3°... lower than the displayed
temperature.
NOTE
The units are shipped out with all their data being cleared. i.e. the setting values are "0" for all
together. But, for the purpose of quality improvement, the settings can be changed before
being shipped out, make sure to check relevant SVC bulletins.
2) With the Option Setting mode, "0" blinks on both of the Fridge and the Freezer sections. (Generally,
they are set to "0" at both the Fridge and the Freezer sections. But, they can be changed for the
purpose of quality improvement.) - When "0" blinks on the Fridge section, it is set to the Freezer
Option Setting and the Freezer temp code will be displayed on the Freezer temp section.
3) If the Freezer temp code is set to "6" as the following table after setting the Fridge section to "0", the
Freezer base temperature is to be lowered by -3 (Refer to the Freezer temperature setting image.)
Option Value
: In 15 seconds after completing the adjustment, MICOM is to store the setting value in EEPROM and
it goes back to the normal display mode, deactivating the Option Setting mode.
4) The above Option Setting is the same for both of the Dispenser model and the No-Dispenser model.
5) With the same method as the above, you can control the Fridge temperature, the water supply
quantity, the Ice-Maker sensor temperature.
6) Make sure not to change the factory-set default values otherwise exception cases. Also, the Option
Setting is to be completed when it goes back to the normal display mode in 20 seconds. So, do not
turn off the unit before it goes back to the normal display mode.
NOTE
There are more functions which can be adjusted. But, they are not to be described in this
manual because they are not actually related to the diagnosis of the unit. (Do not change the
option settings other than the ones described in this manual)
that is even though it shows -18
