SAFETY For your own safety, unplug the refrigerator from the electrical outlet before servicing the appliance.
- Page 5 FEATURES A. Temperature Control Operation The internal temperatures of the freezer and fresh food compartments can be regulated individually to maintain better food conservation conditions, thus optimizing the use of the appliance. These models feature controls for better temperature monitoring, one for the freezer and one for the fresh food compartment.
- Page 6 Operating Instructions for the External Controls Vacation Mode Directly enabled by pressing the button (when enabled, the indicator light will turn on). It is disabled by pressing the button or by opening the fresh food compartment door for more than 10 seconds. You will also see in the digital display an indicator light that swirls quickly.

Page 8: Thermal Protector
CAPACITOR TO THERMAL PROTECTOR CONNECTION THERMAL PROTECTOR This component (installed in the compressor body) quickly detects any abnormal increase in temperature or excess current caused by a failure of the electrical or mechanical system or an inappropriate application. This compressor element consists of a bimetallic disc which, when it detects an excessive temperature in the compressor or when its integrated resistance becomes too hot, due to an excessive current, bends and disconnects the compressor, and the disc returns to normal electric contact when it cools off. -
Page 9: Electrical System
SAFETY Before plugging the refrigerator into the electrical outlet, please make sure that: All electrical connections are grounded and all wiring harnesses are connected, away from the sharp edges of the metal plates, and that both the internal and external grounding connections of the appliance are properly connected. -

Page 11: Defrost Circuit
DEFROST CIRCUIT The defrost circuit has a series of components that allows the disintegration of the frost formed during the cooling cycle: control board, defrost sensor, relay number 2 in the board, output port in the board, defrost thermostat, fuses and resistance (heater). -
Page 12: Defrost Sensor
If the heater is in circuit (on) for 20 minutes in the defrost cycle, the following cycle is increased by 2 hours; if it is connected for 30 minutes, it is maintained as is; if it is connected for 40 minutes, it is decreased by 2 hours. - Page 13 Evaporator fan motor Condenser fan motor assembly...
- Page 14 For these models THERE ARE 2 DIFFERENT TYPES OF ELECTRONIC BOARD: ONE FOR THE STANDARD AND DELUXE (“X”, “Y”) MODELS, which are models with BASIC ELECTRONICS (see factsheet PTR05014), and ANOTHER ONE FOR SUPERDELUXE (Z) MODELS, which have an EXTERNAL DISPLAY (see the following photos). The different boards that have been used for the Polar, Polar Display and now Sedna models have a different adjustment and/or setting.

OPERATION CHECK. DEFROST CYCLE OPERATION. A) DISASSEMBLE THE CONTROL BOARD AND REMOVE THE EVAPORATOR COVER.
- Page 16 DIRECT TEST FOR THE ELECTRONIC BOARD REGULATED VOLTAGE TEST OF THE BOARD The tests described here must be carried out with the sensor located in the fresh food compartment and the potentiometer (temperature control) integrated to the board. In case any of these components is damaged, the whole assembly must be changed because each board is calibrated with these components.
- Page 17 For these models THERE ARE 2 DIFFERENT TYPES OF ELECTRONIC BOARD: ONE FOR THE STANDARD AND DELUXE (“X”, “Y”) MODELS, which are models with BASIC ELECTRONICS (see factsheet PTR05014), and ANOTHER ONE FOR SUPERDELUXE (Z) MODELS (see factsheet PTR05014), which have an EXTERNAL DISPLAY (see the following photos).
- Page 18 When applying voltage to the white and black cables the board is energized and 10 seconds later it sends a signal to the compressor to start working. You must now bridge test points GND and P.P., which will turn off the compressor. Three seconds later, a signal will be sent to the defrost resistance to start working and, at this moment, the white and blue cables must give a reading of 127 A.C.V.

Page 19: Thermistor Test
THERMISTOR TEST Thermistors vary their resistance value according to the temperature they detect. For example, at room temperature they have low resistance. When the temperature decreases, the resistance value increases. The following table shows the approximate readings based on a temperature scale. In fact, what is actually important about thermistors is that they must not show a reading of infinite value (open) or zero resistance (closed), and when they turn hot or cold their resistance value must vary. -
Page 20: Special Features
SPECIAL FEATURES SUPER COOLING FEATURE (QUICK COOLING) When this function is selected, the LED2 light turns on, which indicates that a signal is being sent to the board. When the shut-off temperature indicated by the thermistor and the potentiometer is reached, the board does not send the shut- off signal to the compressor, which continues operating non-stop for an hour. - Page 21 Evaporator cover assembly Airflow system Defrost system components are: the thermostat, the thermistor and the resistance (heater) Defrost drainage system.
