Introduction - Electrolux COMBI “Zero Degree” Service Manual

This manual deals with the Zero Degree COMBI refrigerators produced in the Susegana factory (ZS).
It is a two-compressor combined appliance with PNCs: 925 703 xxx (KBI0280 DOD).
The cooler/zero degree and freezer compartments are independent; therefore it is possible to switch them on/off
according to the necessity.
The appliance is equipped with the following compartments:
cooler and Zero Degree;
freezer.
The evaporator circuit consists of:
battery evaporator (Zero Degree and cooler compartment);
evaporating tower (freezer compartment).
The appliance is controlled by the ERF2050 electronic system for the power and ERF2000 for the display.
KEY:
A = cooler compartment;
B = separator;
C = Zero Degree compartment;
D = freezer compartment.
A separator is placed between the refrigerator compartment and the Zero Degree compartment. This separator
is contoured at the front (near the door) to allow air to flow between the compartments.
Unlike No Frost refrigerators, the Zero Degree refrigerator is equipped with a battery-type evaporator that does
not have a heating element (for defrosting) or the relative thermal safety switches, since this evaporator is
defrosted by a fan which operates when the compressor is off.
