4. TROUBLESHOOTING
● When the Display Panel converts to the Option Setting mode, the entire Display except the Freezer and
the Fridge Temperature LEDs as shown below Temp LED goes off.
1) For example, if you want to shift the standard temp of the Freezer compartment by -2℃, follow the steps
below. This function is to change the default temperature and when the default temperature of the
Freezer compartment is -21℃ and the default setting is lowered by -2℃ with the Option function, the
default temperature will be controlled at -23℃. That is, when changing temperature options, the Freezer
compartment will operate at -23℃ internally even if it shows -21℃ on the display panel. Therefore, the
temperature will be controlled by -2℃ lower than the set temperature on the display panel.
Note Basically, when units being shipped out, all the data in the Option function are cleared. That is, the
Default settings are "0". However, for the purpose of quality improvement during mass production, the
Default values may change. Therefore, be sure to check quality information, such as SVC bulletins.
2) After changing into the Option mode,"0" on both of the Fridge and Freezer compartments lights up on the
display panel. (when units being shipped out, the unit will be shipped out with "0"s set on both of the
Fridge and Freezer compartments. However, for the purpose of quality improvement during mass
production, the Default values may change.)
- When the Fridge Display set to the status of the Option #0, it will be set to the Freezer Temperature
Option and the current Freezer Temperature Set Value will be shown on the Freezer Temperature Display
(Refer to the Freezer Temp Shifting Image).
3) When "4" is set as shown in the Freezer Option Table below after setting the Fridge Option # to "0", the
Freezer default temperature will decrease by -2℃. (Refer to the Freezer Temp Shift Figure)
:In 20 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.
5) The Fridge temperature can be adjusted with the same method.
6) Make sure not to change the factory-set default values excluding exceptional circumstances.
Also, the Option Setting will 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.
