5. Troubleshooting when error happens
( If the relative parts is normal, Error code display will be reset. )
1) Freezer sensor error
- Cause : Freezer sensor disconnection or short.
- Check point : Measure the resistance between both terminals after separating CN9 of the Main PCB.
If sensor is disconnected or short, change that in the freezer compartment.
- Error code display
Freezer sensor is short. Freezer sensor is disconneted.
2) Refrigerator sensoer error
- Cause : Refrigerator sensor disconnection or short.
- Check point : Measure the resistance between both terminals after separating CN8 of the Main PCB.
If sensor is disconnected or short, change that in the refrigerator compartment.
- Error code display
Refrigerator sensor is short. Refrigerator sensor is disconneted.
3) Room temperature sensor error
- Cause : Room temperature sensor disconnection or short.
- Check point : Measure the voltage of sensor part on the Main PCB.
FUNCTIONS ( Error Display_Basic Model )
If voltage is 0.5~4.5V, normal. If voltage is 0V (short) or 5V (disconnect), change new one.
- Error code display
RT sensor is short. RT sensor is disconneted.
4) Defrost sensor error
- Cause : Defrost sensor disconnection or short.
- Check point : Measure the resistance between both terminals after separating CN9 of the Main PCB.
If sensor is disconnected or short, change that on the evaporator.
- Error code display
Defrost sensor is short. Defrost sensor is disconneted.
5) Refrigerator door switch error
- Cause : When it senses the door open for more than 1 hour.
- Check point : Check the each door switch and exchange.
6) Freezer door switch error
- Cause : When it senses the door open for more than 1 hour.
- Check point : Check the each door switch and exchange.
7) Cycle error
- Cause : When compressor works for over 3 hours although Defrost sensor is over -5C.
- Check point : Refrigerant leakage.
8) Abnormal defrosting end error
- Cause : in case defrosting mode ends after 80 minutes.
