If The Trouble Is Detected By Self-Diagnosis - Samsung RF267AARS Service Manual

TROUBLESHOOTING

4-2-1. If the trouble is detected by self-diagnosis

- The error of sensor will be displayed on the front of display.
when the error of sensor is detected at initial power ON, the appliance will not operated and display
of abnormal sensor part will blink.
- The appliance will not stop operating when the error of sensor is detected during operation of the
appliance.
But normal freezing might be not operated if the appliance is operated by the emergency operation
mode. You would better to check the appliance according to the self-diagnosis of the manual.
