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.
Freezer sensor is disconneted.
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.
Refrigerator sensor is disconneted.
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.
RT sensor is disconneted.
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.
Defrost sensor is disconneted.
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.
