1. INTRODUCTION SAMSUNG side by side refrigerator 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. INSTALLATION 1) To protect refrigerator in movement Use padded hand truck as shown. If entrance width is less than 39 〃 , remove doors prior to installation and reattach doors according to procedure below. 2) Remove all protective tape and pad in refrigerators. Connect water lines and power cord.

Circuit Descriptions Note) 1) F-DEF-sensor and Bimetal work in parallel. 2) At the first power on, an open error (5V input to MICOM) can be detected by self-diagnostics. A short error will be ignored. 3) In self-diagnostics during a normal operation, only an open error can be detected.
Page 41
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).
Circuit Descriptions 10-7) CoolSelect Zone Panel Circuit 1) CoolSelect Zone display panel and temperature sensor 1-1) CoolSelect Zone is referred to as a storage drawer to implement features of Quick cool, Thaw, and Select (Soft Freeze, Chill, and Cool). 1-2) CoolSelect Zone has an additional display panel.
Circuit Descriptions 2-1) CoolSelect Zone Drawer is controlled by a damper to supply or block cold air. For Quick Cool, the damper will be close. So cold air is supplied only to CoolSelect Zone Drawer. For Thaw, the evaporator heater of refrigerator is ON and the damper is controlled by the refrigerator temperature.
Circuit Descriptions 1-3) When the motor rpm is in 600∼700, it will stop automatically and it tries to resume after 10 seconds. If the motor is not working properly after 5 time trials, it will rest for 10 minutes, then try to resume again. This process will be done continuously.
