Fault Analysis
Maintenance
Measures
8. Displayed temperature is
different from actually tested
temperature
1. The user's test instrument is not accurate
Change the test instrument
2. Temperature probe of sensor is not accurate
under locked state
，
press down
"temperature" button until
temperature calibration value
displays flickeringly on the displaying
area of setting temperature, now you
can set a new temperature calibration
value.
3. Displayed temperature is the temperature at
the temperature-control probe, it is normal that
there is certain temperature difference between
upper part and lower part in refrigerator.
9 Temperature difference
between upper part and
lower part in refrigerator is
too large
If a user opens and closes the door frequently
，
it is normal that temperature inside the box is
unstable, it is not fault.
Reduce the times of opening and
closing the door.
It is normal that there is temperature difference
between upper part and lower part in low
temperature cabinet.
10. it Displays that inside
temperature sometimes is
high and sometimes is
low(Sometimes more than
20 °, sometimes below zero)
Computer board has a failure
，
refrigerating
system can not work normally.
Change the Computer board
11. Display E0 or other signs.
Master sensor fault: E2
，
condenser- sensor
fault: E1
，
ambient temperature sensor fault: E0
Check if sensor contact is bad or
not
，
otherwise, change the sensor.
12. The start of high
temperature level
compressor is normal
，
but
Low temperature level
compressor protection is not
normal, does not start and
fails to refrigerate.
High temperature level refrigerant leaks
Maintenance high temperature level
compressor.
13 Temperature can only be
maintained at about 50° for a
long time, and temperature
neither rises nor falls, and the
machine is operating
normally.
Low temperature level refrigerant leaks
Infuse refrigerant
Refrigeration pipe line is blocked
After shutdown, open the cover to
balance inside and outside
temperature
，
then start up again.
Infuse refrigerant again
，
and change
the filter.
14. It displays that voltage is
high or low
Displayed voltage is the voltage at the user’s
socket
，
it is normal.
