chamber
Yes
On of LED1
and LED2
simultaneously
Step 1: Check whether the terminal CN3 is well
stuck, pull out the terminal and re-stick it in place
Step 2: Check to see if therere foreign matters on
the terminal. Pull out the refrigerating sensor
according to the method in described in Article
8.4 and then inspect the sensor against the
resistance value table in 10.8.
Step 3: Replace main control board
Step 4: Replace electrical wiring main harness

9.9Defrosting function
1.Defrost the freezing chamber as per the accumulative operation time of the Compressor2.If
power failure occurs abruptly to the Compressor and the defrosting sensor in freezing chamber is
less than 0
o
C after powering on, then first conduct defrosting once. If more than 0
o
C, then
defrosting is not needed.
After that, conduct defrosting according to using condition and ambient temperature in a period
between 6 and 24 hours as per the accumulative operation time of the Compressor.
