1-8. ICE PLUS 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, ICE PLUS will be canceled. 4) To activate this function, press the ICE PLUS 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 ICE PLUS 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 during the first 90 minutes of ICE PLUS, the ICE PLUS cycle will complete its cycle after defrosting has ended. If the defrost cycle begins when ICE PLUS has run for more than 90 minutes, ICE PLUS will run for two hours after the defrost is completed. (3) If ICE PLUS is pressed during defrost, ICE PLUS icon is On but this function will start seven minutes after defrost is completed and it shall operate for three hours. (4) If ICE PLUS 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 ICE PLUS. (6) For the rest of the 21 hours, the freezer will be controlled at the lowest temperature. 1-9. Control of variable type of freezing fan 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, ICE PLUS, load response and Test mode 1 for the high RPM speed and operates in the standard RPM in other general operation. 3) If the freezer door is opened while the fan motor is operating, the fan motor will continue to operate normally. (If the fan motor is running at high speed, it will automatically be reduced to the standard speed). However, if the refrigerator door is opened, the freezer fan motor will stop operating. 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 115 seconds 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. 1-10. Control of cooling fan motor 1) The cooling fan motor performs ON/OFF control by linking with the COMP. 2) It controls at the single RPM without varying RPM. 3) Failure sensing method is same as in the freezer fan motor (refer to failure diagnosis function table for failure display). 1-11. Door opening alarm 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. 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.
