When the freezer
temperature is abnormally
high or the freezer door is
open for a certain period
of time and the freezer compartment. If the reason for
temperature increases, the the error is removed, the error
freezer display blinks.
When the fridge temperature
is abnormally high or the
fridge door is open for a
certain period of time and compartment. If the reason for
the fridge temperature the error is removed, the error
increases, the fridge display
blinks.
When the Compressor fails

When there is a IPM Fault
error
Check the Compressor and the

Diagnostic method
Actually, If there is not a
problem, it is desirable to
replace Main and Panel PCB
With the oscilloscope after a
cable problem confirming.
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
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
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]
Cycle
Check the Compressor
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
