” and two digit error code flashes alternately as shown in the right figure.
When several errors occur, they are displayed alternately. However, the error whose code has
a smaller number has priority to be displayed first.
(Ex.) In case the errors of ice tray thermistor (
ee1100
), refrigerator thermistor (
ee1133
) and refrigerator
fan motor (
ee3311
) are happening simultaneously;
✻ For 2 minutes in self-check, a high-tone sound is heard due to the operation check of damper.
2. Check point and treatment
(Ex.) When ice maker gear
box is defective.

(2) Timing in self-check
Trouble of Defrost heater : Self-check is conducted after defrosting.
(Make sure to confirm the display before unplugging the power cord
because it is automatically reset once the power cord is pulled out.)
Trouble of Ice maker : Press the switch on the panel for 5 seconds. (Ice making test mode.)
The setting of ice making compartment blinks on LCD during the test operation.
Trouble of Fan motor : Open the door and then closed it.
When abnormality is found in fan motor, buzzer sound is heard every time the door
is closed.
Trouble of Inverter : Check the error when compressor starts up or is operating.
Trouble of Thermistor : Self-check is continuously working
