Operation; Normal - Electrolux FROST REFRIGERATORS with ERF2021 electronic Service Manual

Warning: Disconnect the appliance from the electric power before operating with the appliance.
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, heaters)
When the appliance is off then:
the compressor is off
the display is off
Pushing down the ON/OFF button, the LCD display switches on with the following displaying:
room temperature with the relative symbol;
sign +;
display with red background;
freezer compartment temperature alarm (buzzer active).
Push the function activation button to deactivate the buzzer sound.
Position the knobs of the compartments on the upper green side so as to set the following temperatures:
about +5 °C in the cooler;
about -18 °C in the freezer.
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 normal operation time the electronic board powers the compressor (2) and the fan (24) circuits.
The operation of the fan is independent from the operation of the compressor (the fan is on only when the
compressor is on).
The fan is activated or deactivated with a 2 minute delay compared to the compressor.
The operation time which corresponds to the interval between the following defrosting lasts about 14 hours with
normal opening of the door (it can last up to 72 hours if the doors are never opened).
