1

F-DEF ERROR

[ Freezer Defrost Heater ]
Connector Slipped-Out or Open-Contact, Wire Cut or 
Short-Circuited, Defective Thermistor [Fridge 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 CN30-"2(WHT) ↔
1(WHT)" should be within 4.5V~0.5V

3

F-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 CN30-"3(GRN) ↔
1(WHT)" should be within 4.5V~0.5V

4

R-SENSOR

Same as the EXT - SENSOR

The voltage between MAIN PCB CN30-"5(BLU) ↔
1(WHT)" should be within 4.5V~0.5V

5

F - DEF - 

SENSOR

Same as the EXT - SENSOR

The voltage between MAIN PCB CN30-"4(YEL) ↔
1(WHT)" should be within 4.5V~0.5V

6

Vacation 
LED Lad

R-DEF-SENSOR Same as the EXT - SENSOR

The voltage between MAIN PCB CN30-"4(YEL) ↔
1(WHT)" should be within 4.5V~0.5V

7

F-FAN ERROR

Same as the EXT-Sensor

The voltage between MAIN PCB CN30-"6(RED) ↔
7(Gray)" should be within 4.5V~0.5

8

C-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 CN75-"2(BLU) ↔
1(GRY)" should be within 7V~12V

9

Power 

Freeze LED 

LAMP

R-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 CN75-"3(ORG) ↔
1(GRY)" should be within 6V~12V

10

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 1 3.5V. 
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.)

Comp over 

voltage error

The error code is displayed when the AC Input 
Voltage is too high.

Check the input voltage. 
(This error occurs when the input voltage is AC 310V 
or higher.)
