36’’ 3 DOORS WARDROBE TYPE REFRIGERATOR

/ REV

NO: 00

FF Eva sensor (Fridge Compartment Eva Sensor):

It is used to detect the tail Evaporator temperature of the

Fridge compartment.

Defrost sensor:

It is located on the evaporator at the capillary outlet. It detects the temperature on the

evaporator and transmits it to the microprocessor. Defrost is terminated according to the temperatures received
from this sensor.

Freezer defrost heater:

The heater under the freezer evaporator is activated and deactivated by the electronic

card at times of defrost. In this way, it periodically defrosts icing accumulated on the evaporator.

Flange Heater:

It is used to prevent condensation on the contact surface of Freezer Door seals.

Thermal fuse:

It is located on the evaporator. In case of any malfunction, it cuts the current to the heater to

deactivate the defrost heater in order to prevent the defrost heater from remaining activated continuously and
doing any damage to the refrigerator, environment and foods inside. Thermal fuse is disposable and therefore
it must be replaced once it is blown.

PTC relay:

It has a characteristic that its resistance increases as the temperature rises. It ensures primary

start-up of the compressor by activating the compressor's auxiliary coil, then it deactivates the auxiliary coil by
being heated with the current flowing over it.

Thermal:

It is a component that becomes open circuit when heated. It opens the circuit at a certain

temperature and cuts the current to the compressor in order to protect the compressor coils against excessive
heating. When the temperature of the compressor drops below a certain value, it re-completes the circuit to
operate the compressor.

Upper hinge cover Reed Switch:

Reed switches are used in the upper hinge cover with display. Normally,

once the cooling doors are closed it is in closed circuit. When the cooling doors are open, a signal is
transmitted to the control board and thus, FF illumination units are lit and disabled if the fan is running. When
the door is closed, lamps are turned off and the fan starts running if needed.

DC Led Bar and DC ATK Led Board

6 units of 12V DC LED boards are used for the illuminating fridge

compartment. These LED boards are activated by the reed switch and control board when the fridge
compartment door is opened. 1 unit of 12V DC LED boards are used for the illuminating the fridge
compartment. This LED board is activated by the reed switch and control board when the freezer 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 the info to the microprocessor. Thus the motor of the icematic is rotated according to the
temperatures detected from the sensor.

Icematic Sensor:

The icematic accessory in the freezer compartment is used to detect the ice quantity in the

icebox.

Icematic motor:

It ensures discharging 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.

Blue light LED board:

Blue light LEDs are used to ensure longer preservation of vegetables. It is used along

with the rear illumination units of cooler compartment on the lower section.

Ioniser:

It periodically spreads ions into the FF compartment in order to clean the air inside the compartment. It

is used on the upper section of the fridge compartment and behind the fridge eva cover.
