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 of freezer sensor in 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 of refrigerator sensor in 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.
FUNCTIONS ( Error Display )
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 of defrosting sensor in 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.
16

7) Et error
- Cause : Level switch abnormal. ( No pulse is sensed for some time. )
- Control : By time. ( Supply mode is skipped. )
8) Eg error
- Cause : When Ice sensor temperature ( 5 minutes after water supply ) doesn't go up.
- Check point : Ice sensor or water supply line.
9) EA error
- Cause : When sensing ice drop 3 times in level sensor switch error.
- Control : Stop ice maker
- After 1 time rotation EA error code disappear if level swtich is normal.
10) Eu error
- Cause : Sensor which senses if ice is full or not is abnormal.
- Control : When drops the ice, the motor rotates 90 degree.
FUNCTIONS ( Error Display )
11) C1 error
- Cause : When compressor works for over 3 hours although Defrost sensor is over -5C.
- Check point : Refrigerant leakage.
12) F3 error
- Cause : in case defrosting mode ends after 60 minutes.
- Check point : Measure the resistance between both terminals of the defrost heater.
If the resistance is infinity (disconnection) or 0 ohm (short).

- Ice tray rotation to separate ice cubes
- water supply to ice tray
- check if water supply complete or not
1) Press Test switch ( which is under the ice tray ) for more than 1 second and then test starts.
- Test mode starts from ice separating mode.
- In case test switch is abnormal, test is done only 1 time.
2) When the initial power input, ice tray turns to be horizontal.
3) Water supply hose heater control - defrost heater linkage operation
- Heater is always ON if Room temperature sensor is abnormal or room temperature is below 15 degree.
- Heater is ON for 60minutes (max limit time) if Flow sensor is abnormal.
4) Water supply stand by
- Condition : When ice is full
- Operation : Proceeds to ice making mode. ( stop ice separating and water supply mode )
5) Crusher function
- It stops operation when freezer door is open.
- It operates if door is close.
