After conducting the self-check referring to 5-2(1),
flashes repetitively and the error code is displayed. The tens
place and ones place of the error code is displayed separately.
When two or more errors occur, they are displayed alternately. The error of which code has smaller number has priority
to be displayed first. There are 0.5 seconds intervals between the error codes.
(2) Timing in self-check
Trouble of Defrost heater
: Self-check is conducted after defrosting.
(Make sure to check the display before unplugging the power cord because it is
automatically reset once the power cord is unplugged.)

operation.
Trouble of Fan motor
: Open the door and then close it.
When any abnormality is found in fan motor, the alarm sounds every time the door is closed.
Trouble of Inverter
: Check the error when the compressor starts up or is operating.
Trouble of Thermistor
: Self-check is continuously working.
For 2 minutes in self-check, a high-tone sound is heard due to the operation check of damper.
2. Check point and corrective measures
e.g.) The errors of refrigerator thermistor (
E13
) and ice maker gear box
(
E33
) are occurring simultaneously.
