After the setting is complete, the kinds of thermistor and its temperature are alternately shown on the panel. In case of abnormality, the display returns to current temperature. Please note that the temperature detected by thermistor may be a little different from the real one due to the influence of refrigerator temperature.

Follow the procedure above to release this mode. For the prevention of the compressor, avoid releasing

 

 

it by plugging and unplugging the power cord.

(6) Change mode of compressor rotational speed

Operation sound can be checked by changing the rotational speed of compressor. Always conduct a check while the compressor is operating and the “-” mark is not on the display, which shows the compressor stops. If the “-” mark is on the display, unplug the power cord and then plug it in a few seconds to operate the compressor. Also, this function is not available during the following modes: Child lock, Demonstration, Cooking timer, Thermistor temperature check and error code display.

for about 3 seconds until a “beep” sound is heard, and “88” blinks.

 

 

 

 

 

 

Press with the door left open.

2Changing the rotational speed

After the setting is complete, press and the rotational speed of compressor alternately changes in 6 steps.

The rotational speed (rps) is shown on the panel. Basically the compressor starts operating at level 5, however, it depends

on model or specification change.

WNote: Operation sound may get increased in the process of changing the speed, but that does not mean any problem. Check the operation sound when the rotation is stabilized.

3 ON and OFF of machine chamber fan motor

 

Under this function, fan motor in machine chamber can be switched on and off at each press of

switch.
