http://svc.dwe.co.kr Nov. 2003
There was an engineering change in Side By Side Refrigerators.
The function that controls Top Hinge's left and right side was removed.
As a result, "Installation Guide" was modified and "Screw Machine" was deleted in service manual.
This change took effect on Nov. 11th, 2003.
So please refer to the revision service manual for the SBS models produced after Nov. 11th, 2003 .

SAFETY AND PRECAUTIONS
1) For starters, be sure to check any chances of the leakage of electricity
2) You could handle a part in the vicinity of electricity after unplugging
3) You should put on rubber glovers to prevent an electric shock on operation test
4) Make sure the rated current, voltage, capacity before using an instrument
5) Keep your wet hands away from the metal goods in the freezer compartment not to be frostbitten
6) Be careful not to let water to permeate the electric part in the machine room
7) with the door open during your working, you might be damaged by that door
8) You should give a tilt to the refrigerator for your safe after removing the breakable
goods inside the refrigerator
9) You'd better use cotton gloves if you fix it up around the evaporator

5. Prevention of weak/poor-refrigeration
1) When weak refrigeration is sensed, comp. is ON regardless of F-sensor.
2) When R-sensor reaches R-fan OFF point, comp. is controlled by F-sensor and
R-fan turns OFF.
3) Sensing point of weak refrigeration : R-sensor OFF point of each mode + 7C

3. F-FAN
4. CUSTOM-LCD
CONTENTS REMARKS
1. This mode starts with a push of “SLEEP”button.
2. Conditions to start Sleep mode
1) F-sensor <-13C
2) Unless it is a restart within 40 minutes after the end of previous Sleep mode
3) F-sensor error
4) Door switch error
5) Defrosting (Heater defrosting, pause, Fan delay)
6) If the above conditions of 1) ~ 5) are all satisfied, the sleep mode starts.
3. Control of electrical parts
1) Mode 1
Once Sleep mode starts, all the electrical parts (COMP, F-FAN, R-FAN) turn OFF.
(“ON”letters of SLEEP on LCD is display.)
2) Mode 2
It operates with Silent mode and “ON”letters of SLEEP on LCD is displayed on.)
4. Termination of Sleep mode
1) MODE 1
a. F-sensor >-9C
b. In case of F-sensor error
c. When other button is pushed during this mode
d. Total F/R door open time exceeds 30 seconds during the mode
e. If Sleep mode is terminated by a, band f,F/R-fan delay for 5 minutes and
restart of this mode is prevented for 40minutes.
f. It it exceeds time limit of 130 minute, Mode1 is terminated and Mode2 starts.
2) MODE 2
Sleep mode is terminated 12 hours after the first start.
( Speed mode and defrosting operate in normal way.)
5. After Sleep mode stops all the electrical parts return to normal operation and Sleep
icon changes from “ON”to “OFF”.
6. If Sleep mode starts during PRECOOL, it goes on again after the Sleep mode is
terminated.
7. If Sleep mode starts during Super FRZ., Super REF., it returns to previous set
modeafter the Sleep mode is terminated.
