When the freezer temperature
is abnormally high or the
freezer door is open for a
certain period of time and the
freezer temperature increases,
the freezer display blinks.

Diagnostic method
The voltage of MAIN PCB CN52
2PIN - 3PIN shall be between
7V~12V
Actually, If there is not a problem,
it is desirable to replace Main and
Panel PCB With the oscilloscope
after a cable problem confirming.

It is desirable to replace Main
PCB.
The temperature has been
abnormally increased. Check
if the door has been open
for a long time or if hot
food has been stored in the
compartment. If the reason for
the error is removed, the error
code disappears after a pre-
determined period of time.
Check if door has been
open for a long time or if hot
food has been stored in the
compartment. If the reason for
the error is removed, the error
code disappears after a pre-
determined period of time.
Check if there is a short
between compressor
terminals. Check IPM Voltage
[Under 13.5V] Check if there
is a short between IPM Pins
[#1~33]
Check the Compressor and
the Cycle
Check the Compressor
connections Check the voltage
of Resistance of R308
[0.09Ohm] Check the
Compressor and the Cycle
Check the voltage of
Resistance of R308 [Short/
Open] Check the voltage
of both of C103 terminals
[Unstable Voltage] Check the
Compressor and the Cycle
Check the voltage of
Resistance of R513 [Short/
Open]
Check the voltage of
Resistance of R501, R505,
R509 [Short/Open]
