1-8. ULTRA ICE
1) The purpose of this function is to intensify the cooling speed of freezer and to increase the amount of ice.
2) Whenever selection switch is pressed, selection/ release, the icon will turn ON or OFF.
3) If there is a power outage and the refrigerator is powered on again, ULTRA ICE will be canceled.
4) To activate this function, press the ULTRA ICE key and the icon will turn ON. This function will remain activated for 24 hrs.
The first three hours the compressor and Freezer Fan will be ON. The next 21 hours the freezer will be controlled at the lowest
temperature. After 24 hours or if the ULTRA ICE key is pressed again, the freezer will return to its previous temperature.
5) During the first 3 hours:
(1) Compressor and freezer fan (HIGH RPM) run continuously.
(2) If a defrost cycle begins the first 90 minutes of ultra ice, the ultra ice cycle will run for remaining time after the defrost is
completed. If the defrost cycle begins when ULTRA ICE has run for more than 90 minutes, ULTRA ICE will run for two hours after the
defrost is completed.
(3) If ULTRA ICE is pressed during defrost, ULTRA ICE icon is on but this function will start seven minutes after defrost is completed
and it shall operate for three hours
(4) If ULTRA ICE is selected within seven minutes after compressor has stopped, the compressor (compressor delays
seven minutes) shall start after the balance of the delay time.
(5) The fan motor in the freezer compartment runs at high speed during ULTRA ICE.
(6) For the rest of the 21 hours, the freezer will be controlled at the lowest temperature.
1) To increase cooling speed and load response speed, MICOM variably controls he freezer fan motor at the high RPM speed and
standard RPM.
2) MICOM only operates in the input of initial power, ULTRA ICE, First cylce after defrosting Test mode 1 for the high RPM speed
and operates in the standard RPM and low RPM in other general operation.
3) If opening doors of freezing / cold storage room while fan motor in the freezing room operates, the freezing room fan motor
normally operates (If being operated in the high speed of RPM, it converts operation to the standard RPM). However, if opening
doors or Refrigerator Room, the freezing room fan motor stops.
4) As for monitoring of BLDC fan motor error in the freezer, MICOM will immediately stop the fan motor by determining that the
BLDC fan motor is locked or failed if the fan motor position does not change for more than 65seconds at the BLDC motor.
Then a failure code will be displayed (refer to failure diagnosis function table) on the refrigerator, for BLDC motor failure. If you want
to operate the BLDC motor, turn off and on at the power source.
1) The cooling fan motor performs ON/OFF control by linking with the COMP.
2) Failure sensing method is same as in the freezer fan motor (refer to failure diagnosis function table for failure display).
1) The buzzer will sound if the freezer or refrigerator doors have been left open for longer than one minute.
2) The buzzer will ring three times every 30 seconds if the doors have been left open for longer than 1 minute.
1-9. CONTROL OF VARIABLE TYPE OF FREEZING FAN
1-10. CONTROL OF COOLING FAN MOTOR
1-11. DOOR OPENING ALARM
3) Closing all refrigerators doors will stop the Buzzer alarm function.
4) If all the doors of freezing / cold storage room or Refrigerator Room are closed during door open alarm, alarm is immediately
released.
