2-9. Function of Trouble Diagnosis(88-LED)
1. Failure diagnosis function is function to facilitate service when nonconforming matters affecting performance of product
during use of product.
2. In occurrence of failure, pressing the function adjustment button does not perform function and only alarm sound (“Ding~”) rings.
3. If nonconforming matters occurred are released during display of failure code, MICOM returns to the original state (Reset).
4. Failure code is displayed on the display part of setting temperature for the freezing room and the display part of setting
temperature for the cold storage room of LED, which are placed at the display part of a refrigerator. All the LED graphics
other than a failure code are turned off.
In display of the failure mode, all LEDs of setting temperature for freezing/ setting temperature for cold storage are turned
off (excluding Note1 and Note2).
