operating
Poor contact with the
temperature controller
Inspect whether the connector
assembly is damaged
Insert the connector assembly
tightly
Compressor set
not opening
Temperature controller
damaged
Inspect whether open circuit
exists in two connector
assemblies
Replace the temperature controller
Too mush frosting on
evaporator
Inspect whether thickness is more
than 2mm
Remove the frost timely
Over-high frequency of
opening the door
Reduce the frequency of opening
the door as much as possible
Too mush articles in the case
Inspect whether it is possible to
impact the circulation of cool air.
Take some food out
Over-temperat
ure in the case
Refrigerating fluid leaking
Repair in a maintenance point
machine set
operating
continuously
Over-high ambient
temperature and too low
temperature of the temperature
controller
Inspect whether the knob is put
on Positions “2-4” or forced
cooling

Inspect supply voltage
Connect a voltage stabilizer over
1000V
If the supply cords are damaged, in order to avoid danger, replacement of the supply cords must be carried out by the manufacturer or its maintenance
department
Note: the following phenomenon is not the fault phenomenon
1. Slight gurgle exists in the temperature-changeable freezing refrigerator occasionally;
2 The compressor and the condenser emit heat, even scald hands;
3 It is possible to generate water bubbles outside the refrigerating cabinet when the ambient temperature is higher.
4 The heat of 50 Celsius degree exists outside the temperature outside.
