F R
Dispenser
Panel ↔ Main
Communication
Error
MICOM MAIN ↔ DISPENSER
PANEL communication error.
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 F
compartment
abnormal
hightemperature
indicator blinks
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.
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.
The R
compartment
abnormal
hightemperature
indicator blinks
When the fridge temperature
is abnormally high or the
fridge door is open for a
certain period of time and
the fridge temperature
increases, the fridge display
blinks.
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.
Comp starting
Failure Error
When the Compressor fails
starting
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
IPM Fault Error
When there is a IPM Fault
error
Comp Abnormal
current
Detection Error
When there is abnormal
current detected at the
Compressor
Check the Compressor
connections Check the voltage
of Resistance of R308
[0.09Ohm] Check the
Compressor and the Cycle
Motor Locked
Over RPM Error
When there is a Compressor
restriction error
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
Comp under
voltage Error
When there is a low voltage
error
Check the voltage of
Resistance of R513 [Short/
Open]
Comp over
voltage Error
When there is a over voltage
error
Check the voltage of
Resistance of R501, R505, R509
[Short/Open]
