2-1) Introduction of main function
●
A newly developed SAMSUNG side by side refrigerator in 2005 has the following
characteristics.
1) Twin Cooling System
● The refrigerator and the freezer have two
evaporators. Given this independent system, the
freezer and the refrigerator are cooled 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.
2) Multi-Flow System
● Cool air circulates through multiple vents on every
shelf level. This provides even distribution of cooling
inside cabinets to keep your food fresh longer.
3) Xtra SpaceTM
● Vertical room next to the ice maker in the freezer
provides space for pizza etc.
4) Door Alarm
● Beep sound reminds you the door is open.
5) Xtra FreshTM
● Optimized humidity control keeps vegetables & fruits
fresh.
6) Deodorizer
● Reusable twin deodorizers keep the refrigerator air
fresh and odor free.
7) CoolSelect ZoneTM Drawer(RS267, RS269)
● User can select Quick Cool, Thaw, for quickly chill
items, thaw items. Select Soft freeze, Chill or Cool to
control the temperature of the drawer.

1) Initial Operation function
1-1) Whenever the power is on, the control board checks the ice tray leveling with the leveling switch within 2 seconds.
1-2) If the leveling switch is not off position, the geared motor will turn to the initial position to make the ice tray leveled.
1-3) When the ice tray is leveled, it will remain this position for 2 hours (1 cycle time for ice production).
1-4) After 2 hours, the sensor located under the ice tray will measure the tray temperature. If the temperature is
maintained lower than 1℉ for 5 minutes, and the ice full switch is off position, the ice tray twisting process will
begin.

11. CIRCUIT DESCRIPTIONS
11-1) Source Power Circuit
This circuit shows SMPS(Switch Mode Power Supply) which converts AC input voltage (115V, 60Hz) to a high DC voltage
(170V). 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 and sensor’s
circuits.
Caution) Be careful to handle this circuit due to high voltages (AC115V, DC170V)

11-6) Key Scan and Display Circuit
1) Key Scan and display operation.
The model uses a decorder IC which 4 inputs and 9 outputs.
If the IC 9 decorder (TC4028BP) received signals from
MICOM pins (3∼6), an output signal per 2 miliseconds
comes out from Q3, Q41, Q8, Q6, Q9, Q7, Q0, Q2, and Q4
pin in sequence. This signal enters to a driver IC input
terminal of the CoolSelect ZoneTM PCB and IC5 (TD
62783AP), then approximate 11V peaks will generate from
an output terminal as shown on the next page.
78
11. CIRCUIT DESCRIPTIONS
The step signals of DC 11∼ 12V will be generated periodically. If a sink signal outputs from IC4, DC 11-12V will be
applied to the LED input terminal and sink the LED output terminal to 0V. Therefore, LED will be ON for 2 miliseconds.
2) Key Scan
The 6 step signals, Q6∼Q4 are applied to scan the 6 keys (buttons). When SW6 is pressed, the step signal from Q6
will be reduced to 5V and entered to the MICOM, then MICOM will match a corresponding function for SW6 key.
