Micom Function
2-2. Express freezing
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 30 minutes the compressor, Freezer Fan and Icing Fan will be ON. The next 23 hours 30
minutes the Ice room will be controlled at the Ice room lowest temperature. After 24 hours or if the Ice
PLUS key is pressed again, the Ice room will return to its previous temperature.
5. During the 30 minutes :
(1) Compressor, Freezer Fan and Icing Fan run continuously.
(2) If a defrost cycle begins during the first 15 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 20 minutes,
Ice PLUS will run for 40 minutes after the defrost is completed.
(3) If Ice PLUS is pressed during defrost, Ice Plus Icon is on but this function will start 7 minutes after
defrost is completed.
(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.
6. For the rest of the 23 hours 30 minutes, the Ice room will be controlled at the lowest temperature.
2-3. Control of variable type of freezing room fan
1. To increase cooling speed and load response speed, MICOM variably controls freezing room fan motor at the high
speed of RPM and standard RPM.
2. MICOM only operates in the input of initial power or special freezing operation or load response operation for the high
speed of RPM and operates in the standard RPM in other general operation.
3. If opening doors of freezing /cold storage room or home bar the freezing room fan motor OFF.(12 ~20 seconds)
4. As for monitoring of BLDC fan motor error in the freezing room, MICOM immediately stops the fan motor by
determining that the BLDC fan motor is locked or poor if there is no position signal for more than 65 seconds at the
BLDC motor, it will see it as BLDC Fan motor locked for fan motor defect and immediately stops the fan motor, and
displays error in the refrigerator display
(refer to the failure diagnosis function table) and periodically performs ON/OFF.
2-4. Control of M/C room fan motor
1. The M/C room fan motor performs ON/OFF control by linking with the COMP.
2. The fan motor in the machine room operates in a high / medium / low speed RPM depending on the ambient
lemperature and humidity.
3. Failure sensing method is same as in fan motor of freezing fan motor
(refer to failure diagnosis function table for failure display).
2-5. Control of Ice Compartment Fan
1. The Icing Fan is controlled by the the sensor on the top of the ice compartment.
2. The Failure sensing method is the same as in the fan motor of the freezer
