Error
Defective Thermistor
The error is displayed while
the corresponding fan motor is
operating and a feedback signal
line contact error, motor wire
separation or motor error occurs.
Connector Slipped-Out or Open-
Contact, Wire Cut or Short-Circuited,
Defective Thermistor
Door Handle Heater Open Error
Error
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
blinks
freezer display blinks.
When the freezer temperature is
abnormally high or the fridge door is
open for a certain period of time and
the fridge temperature increases, the
blinks
fridge display blinks.
The error code is displayed when the
error compressor has failed to start.
The error code is displayed when the
Error compressor IPM fault error has occurred.
The error code is displayed when the
compressor location detection failed.
The error code is displayed when the
compressor motor is constrained.
The error code is displayed when the
error AC Input Voltage is too low.
To check if the part is normal
Remove the MAIN PCB CN51 connector form the
MAIN PCB and read the continuity between CN51
#6 ↔ contact point R737 and R776.(Refer to the
Block Diagram for the Resistance Value.
When it reads 0 Ohm, check the Heater short
and when it reads ∞ Ohm, check if the Wire is
open or slipped out.
The voltage of the MAIN PCB CN76 1↔4 : should
be between 7V~12V.
Remove the MAIN PCB CN51 connector form the
MAIN PCB and read the continuity between CN51
#7 ↔ contact point R737 and R776.(Refer to the
Block Diagram for the Resistance Value.
When it reads 0 Ohm, check the Heater short
and when it reads ∞ Ohm, check if the Wire is
open or slipped out.
Remove the MAIN PCB CN51 connector form the MAIN
PCB and read the continuity between CN51 #2 ↔ CN51
#3(Refer to the Block Diagram for the Resistance Value.
For ∞ Ohm, check if the wire is open-circuited or not
connected.
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 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 the soldering status of the inverter PCB. (Check
if any parts have short-circuited). Check if the DC
15V output is less than 13.5V. Check the Comp and
Cycle.
Check the compressor wire connections. Check the
soldering status of the inverter PCB. (Check if any parts
have short-circuited). Check the Comp and Cycle.
Check if the compressor and the Cycle is normal.
Check the input voltage. Check the soldering of the
inverter PCB. (Check if any parts have short-circuited.)
Check the input voltage. (This error occurs when the
input voltage is AC 106 V or lower.)
