Major Feature Twin Cooling System The refrigerator and the freezer have two evaporators. Given this independent system, the freezer and the refrigerator arecooled individually as required and are, therefore, more efficient. Food odor from the refrigerator does not affect food in the freezer due to separate air flow circulation. Multi-Flow System Cool air circulates through multiple vents on every shelf level. This provides evendistribution of cooling inside cabinets keep to your food fresh longer.
Xtra SpaceTM (for RS277 models) Vertical room next to the ice maker in the freezer provides space for pizza etc.
Door Alarm Beep sound reminds you the door is open.
CoolSelect ZoneTM Drawer (for RS277 models) User can select Quick Cool, Thaw and Select buttons to quickly chill, thaw and cool items. Select Soft freeze, Chill or Cool to control the temperature of the drawer.

Reference
CN72 No. 3(F)’ 2(R)’1(C) will get entered pulse signals which are generated when the motor rotates. These signals will be inputted into MICOM. Unless signals are not inputted in the rerun of motor, it will be ON 10 seconds after the fan OFF. But If signals arenot still entered, the above operation will be rerun four times more. Without signals entered continuously, the motor will get restarted after 10 minutes. This function is effective where the normal operation of motor would be restrained due to foreign matters such as ice. 50
Expected causes : 1. Check if the fan motor has failure for itself. 2. Check if the wireconnections have a trouble of contact. 3. Check the input of thefan motor rotation pulse in the operation motor fan. (See the details of FanMotor Drive Circuit section at page 93.)

9. REFERENCE INFORMATION 9-2) CIRCUIT DESCRIPTION 9-2-1) SOURCE POWER CIRCUIT
This circuit shows SMPS(Switch Mode Power Supply) which converts AC input voltage (115V 50Hz, 127V 60Hz, 220V 50~60Hz, 230V 50Hz) to a high DC voltage. The input AC source power is converted to DC through a wave rectifier (BD1) and the converted DC power will generate a constant waveform on the switching transformer using a high speed (100KHz) switching motion of TOP223Y. The D104 will rectify the generated voltage and transform into a steady 12V DC source power used for the digital display panel and relays. The regulator (KA7805) finally transforms into 5V DC source power for the control board andsensor’s circuits.
