Main Functions; Normal; Normal With First Switching On Or Power Failure - Electrolux REFRIGERATION Service Manual

6 MAIN FUNCTIONS

6.1 Normal

Warning: Unplug the appliance before operating.
In case of first switching on with a freezer compartment temperature higher than 10 °C, the appliance operates
with a test cycle (for the factory) for a maximum time of about 1,5 hours.
In this period do not check the correct functioning of the appliance, since the loads are activated only for internal
check (compressor, fan and defrosting heater).
If the appliance is disconnected from the mains power supply:
• the compressor is off
• the LED bar display is off
When the appliance is connected to mains power supply, the display is switched on and the temperature is
displayed through the lighting up of the corresponding LED.
Regulate the temperature of the cooler compartment pushing the temperature selection button so as to set the
following value:
• +5 °C in the cooler
When the cooler door is closed, then all the LEDs are off.
In NOFROST freezers, the humidity inside the freezer compartment accumulates on the evaporator battery
thanks to the air circulation, thus preventing the formation of frost on food.
During the normal operation time, the electronic board powers the compressor and the cold module fan circuits.
The fan and the compressor are powered in parallel, thus they are activated and deactivated at the same time.
The operation time that corresponds to the interval between the following defrosting lasts about 14 hours with
normal openings of the door (it can last up to 72 hours if the doors are never opened!).

6.2 Normal with first switching on or power failure

In case of fault when the appliance is switched on for the first time or in case of a power failure, one of the two
conditions described below occurs:
1. If the internal temperature is higher or the same as the sensor cut-in temperature (CUT-IN), when the power
is restored, the electronic board activates the compressor and the fan till the set temperature is reached and
after 5 hours the electronic board activates the defrosting procedure (after the compressor cut-out)
2. If the internal temperature is lower than the sensor cut-in temperature (CUT-IN), when the power is restored,
the compressor functions in thermostatic conditions and after 5 hours the electronic board activates the de-
frosting procedure (after the compressor cut-out)
The electronic board activates, in any case, the defrosting procedure 5 hours after the first switching on and
after a power failure.
