5. Troubleshooting when error happens
( If the relative parts is normal, Error code display will be reset. )
1) F1 error
- Cause : Freezer sensor disconnection or short.
- Check point : Measure the resistance between both terminals after separating CN15 of the Main PCB.
If sensor is disconnected or short, change that in the freezer compartment.
- Error code display
Freezer sensor is short.
2) R1 error
- Cause : Refrigerator sensor disconnection or short.
- Check point : Measure the resistance between both terminals after separating CN14 of the Main PCB.
If sensor is disconnected or short, change that in the refrigerator compartment.
- Error code display
Refrigerator sensor is short.
3) rt error
- Cause : Room temperature sensor disconnection or short.
- Check point : Measure the voltage of sensor part on the Main PCB.
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.
4) d1 error
- Cause : Defrost sensor disconnection or short.
- Check point : Measure the resistance between both terminals after separating CN15 of the Main PCB.
If sensor is disconnected or short, change that on the evaporator.
- Error code display
Defrost sensor is short.
5) Door switch error ( dr, dF, dH on display )
- Cause : When it senses the door open for more than 1 hour.
- Check point : Check the each door switch and exchange.
6) EI error
- Cause : Ice sensor is abnormal.
- Check point : Measure the resistance between both terminals after separating CN11 of the Main PCB.
If sensor is disconnected or short, change that in the automatic ice maker.
Freezer sensor is disconneted.
Refrigerator sensor is disconneted.
RT sensor is disconneted.
Defrost sensor is disconneted.
