36
Sensitivity: Public
FF Illumination:
One unit of 12V DC LED board is used for the illumination of the fridge
compartment. This LED board is activated by the board when the fridge compartment door is
opened.
Electronic Control Board:
The control board is placed in the plastic box towards the rear
wall on the upper plate of the refrigerator. FRZ is used as the main board which controls the
electronic systems which are controlled by the display on the door.
Icematic sensor:
It is a sensor with flexible body under the icebox. It detects freezing of the
water in the icebox and transmits this to the microprocessor. Thus the motor of the icematic
starts to run according to the temperatures detected from the sensor.
Icematic Sensor: It is used to detect the ice quantity in the icebox of the icematic accessory in
the Freezer compartment.
Icematic motor:
It ensures pouring of the ice formed in the icebox into the ice container. Ice
formation is determined with the information received from the icematic sensor; icebox motor
is activated according to the time of ice formation and the ices are poured into the ice
container. Icematic arm detects when the ice container is full and it does not pour more ice
into the ice container than its capacity.
Water valve:
Water valve group allows sending of the water taken from the mains supply or
from a jug by means of a pump to the water dispenser and to the icebox.
Ice crusher motor:
It drives the accumulated ice in the ice container towards its outlet to help
taking the ice. When ice is needed from the dispenser, the ice crusher motor drives the ice
towards the mouth of the dispenser.
Motor for ice type:
Motor runs to prevent passing of the ice through the blade when ice cube
is selected and the ices sliding from the ice container towards the dispenser are poured into
the dispenser without being broken directly.
Motor to open the ice lid:
When cube or broken ice is selected, flap lid is opened to pour the
ice from the container into the dispenser. This lid is opened by running of the relevant motor.
When the trigger is released, motor runs inversely and the lid is closed.
Ice lid heater:
It is on the surface of the ice lid where the freezer compartment and ambient
temperature encounter. It prevents perspiration.
Water dispenser heater:
It electrically transmits pushing of the water dispenser trigger to the
control board and ensures performing of the selected function.
Blue light LED board:
Blue light LEDs are used to ensure longer preservation of vegetables.
It is located near the filter housing at the lower left part of FF compartment together with the
ionizer.
Ionizer:
It periodically spreads ions into the FF compartment in order to clean the air of this
compartment. It is located near the filter housing at the lower left part of FF compartment
together with the blue light LED board.
Reed switch:
It gives the door open warning. It is located on the upper hinge covers. It is
activated and deactivated by means of the magnets on the door.
