►
If tests have to be conducted while the appliance is live, ALWAYS use a residual-current-operated circuit-breaker!
►
The protective conductor connection must not exceed the standardised values! This is essential for personal safety and appliance function! When0701 repaiorrsthe arecorresponding complete, conduct a test in accordance wias th VDE national regulations as well a performance test! Conduct a leak and performance test on the refrigeration circuit.
514_58300000137976_ARA_EN_H– 26.05.10
Comply with ESD information!
►
NEVER attempt repairs by randomly replacing compone
►
Always proceed systematically and comply with the tec documentation for the appliance!
►
As a rule, printed-circuit boards are not repaired b completely replaced by srcinal spare parts. Exception documented separately.

FC fin ev aporator

TCD Airflow
Two evaporators(FC/RC) are sharing one compressor and one solenoid valve controls the cooling circuit when any compartment needs refrigeration. If the appliance equiped with inverter compressor, the refrigerant goes through the condenser first then the FC heating tube. If the appliance equiped with normal compressor, the refrigerant goes through the FC heating tube then the condenser.

When both compartments need refrigeration, FC has the priorit exchanging time between FC and RC will be 30min/20min.
Ele ctronic control
This appliance is equipped with 5 NTC sensors which control the temperature of FC, RC, TCD, FC-evaporator, RC-evaporator respectively.
During the compartment running progress, when the relevant d open, compressor is still functioning but the relevant fan stops. TCD temperature control
FC/ RC Running and temper ature c ontrol The temperature range of FC is from-16℃ to -26 ℃/ 7℉ to -15 ℉(USA). The temperature range o f RC is from 2 ℃ to 8℃/ 35 ℉ to 46 ℉(USA). When the tem perature of FC or RC ri ses, the control module connect s the solenoid valve (opens to FC evaporator or RC evaporator), FC-fan or RC-fan, compressor, the FC or RC is under cooling. Once the slected temperature is reached, it disconnects the fan, and also closes the s olenoid valve.
The temperature of TCD can only be set as 0 ℃, 2℃, or 4 35.5 ℉or 39 ℉(USA).
When the temperature of TCD rises, the control module conne two flaps, flaps open and TCD fan runs intermittently, the h attached to the air inlet flap stays off. Once the selected tempe is reached, the fan stays off and the flaps are closed, but heate intermittenly.
