Cause : in case defrosting return is done by time limit of 50 min Check point : Measure the resistance between both terminals of the defrost heater.

(Assembled with evaporator)

If the resistance is ∞ ohm (disconnected) or 0 ohm (short) change the

3) “rt” error

Cause : RT-sensor disconnection or short (full down) Check point : Measure the voltage of “A” part on the Main PCB.

If the voltage is 0.5V~4.5V, it is normal. If the voltage is 0V (short) or 5V (disconnected), change the RT-sensor on the Main PCB

How to reset : If F-sensor is normal, the error is terminated automatically.

10) “EF” ERROR

Cause : When Flow-sensor ERROR (There is no Pulse during some time)

The number of pulse signal is below 10 by 1 sec during water supply.

Check point : Water supply line

13) “Ea” error Cause : Malfunction of ice drop motor.

Check the motor by pushing test switch.

11) “Eg” ERROR Cause : I-sensor temp (5min after water supply) doesn’t go up.

Check the I-sensor or water supply line.

12) “ES” error (MICRO switch error) Cause : When it senses 1min continuously

Check the MICRO switch of the dispenser.

14) “Eu” error Cause : Switch (which senses if the ice is full or not) is in error.

Control : When dropping the ice, the motor just rotates 90 degree. Termination : When the switch is in normal.

15)“EA“ ERROR Cause : When sensing Ice dropping by time 3 times in level sensor SW Error.

Control : Stop of Ice Maker Termination : With normal level switch. Re-input of power or push if icemaker test switch.
