TROUBLESHOOTING
Self-Diagnosis Error Description
NO Error Code Item Description Trouble Shooting
1 F-DEF ERROR
[ Freezer Defrost Heater ]
Connector Slipped-Out or Open-
Contact, Wire Cut or Short-Circuited,
Defective Thermistor
Freezer Defrost When the defrosting
does not complete even after it does
defrosting for more than 120 minutes.
Remove the MAIN PCB CN70 and CN77
connectors from the MAIN PCB and
read the continuity between BROWN ↔
ORG wires.
(It differs according to the energy
consumption.)
When it reads 0 Ohm, check the Heater
short and when it reads ∞ Ohm, check
if the Wire/Thermal Fuse or the Bimetal
is Open.
2 EXT - SENSOR
Connector Slipped-Out or Open-
Contact, Wire Cut or Short-Circuited,
Abnormal Sensing Temp
(higher than +65℃ or lower than -50℃)
The voltage between MAIN PCB CN31-
"1(WHT) ↔ 2(WHT)" should be within
0.5V~4.5V.
3 R - SENSOR Same as the EXT - SENSOR
The voltage between MAIN PCB CN30-
"5(ORG) ↔ 7(Gray)" should be within
0.5V~4.5V.
4
F - DEF -
SENSOR
Same as the EXT - SENSOR
The voltage between MAIN PCB CN30-
"4(RED) ↔ 7(Gray)" should be within
4.5V~0.5V.
5 F-FAN ERROR
When the related Fan Motor operates, it
occurs if the contact of the Feed Back
Signal Wire is defective, the Motor Wire
is slipped out or the Motor is defective.
The voltage between MAIN PCB CN72-
"9(S/BLU) ↔ 10(GRY)" should be within
7V~12V.
6
Comp start
failure error
The error code is displayed when the
compressor has failed to start. Check the soldering status of the
inverter PCB.
(Check if any parts have short-
circuited). Check if the DC 16V output is
less than 13.5V. Check the Comp and
Cycle.
Compressor
IPM Fault Error
The error code is displayed when
the compressor IPM fault error has
occurred.
Comp location
detection error
The error code is displayed when the
compressor location detection failed.
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.
Comp motor
constraint error
The error code is displayed when the
compressor motor is constrained.
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.)
Comp low
voltage
error
The error code is displayed when the AC
Input Voltage is too low.
Check the input voltage. (This error occurs
when the input voltage is AC 106 V or
lower.)
Check the input voltage. (This error occurs
