5. Control way of Errors (if any)
1) “F-sensor” error
Cause : F-sensor open or short
Control : Condition of ambient temperature
How to reset : If F-sensor is normal, the error is terminal temperature.
CONTENTS REMARKS
2) “R-sensor” error
Cause : R-sensor open or short
Control : Condition of ambient temperature
How to reset : If R-sensor is normal, the error is terminal temperature.
3) “RT-sensor” error
Cause : RT-sensor open or short (full down)
Control : Normal operation, deletion of control by RT-sensor
If RT-sensor is normal, the error is terminated automatically.
4) “D-sensor” error
Cause : D-sensor open or short (full down)
Control : Time limit (30 min) of defrosting return
If D-sensor is normal, the error is terminated automatically.
5) “Door” error

Control : Deletion of function related door switch sensing
If door switch (open & close) is sensed, the error is terminated automatically.
6) “Cycle” error
Cause : in case comp. works for over 3 hours when D-sensor temp. is over -5
℃
Control : normal operation
When D-sensor temp. is below -5
℃
in comp. off it is terminated.
7) “Return after defrosting” error
Cause : in case defrosting return is done by time limit of 80 min
Control : Deletion of Pre-cool mode in defrosting mode

8) A/S forced defrosting mode
Push “REFRIGERATOR SET” button 5 times while pushing “FREEZER SET” button
Simultaneously.
Control : A/S forced defrosting control (Pre-cool is deleted)
If D-sensor temp. is over 10
℃
, the mode is terminated automatically.
When all error code is normal, the Refrigerator reset
