2. FUNCTIONS
- ERROR DISPLAY
- If appliance has any errors, LED on the Main PCB is flickering.
- If the appliance is normal (no error), LED IS off.
A. 'R1' ERROR
: It happens when R-Sensor is OPEN or SHORT.
(1) LED DISPLAY: Shortly flickering(0.3sec.) 1 times.
(2) CONTROL:
Controlled by the following condition of RT
※
If 'RT ERROR' happens at the same time, “COMP. ON/OFF Operating Time” is 16min/24min.
(3) RELEASE: When R-Sensor is working normally.
B. 'RT' ERROR
: It happens when RT-Sensor is OPEN or SHORT.
(1) LED DISPLAY: Shortly flickering(0.3sec.) 2 times.
(2) CONTROL: Delete the conditions of 'RT-sensor Control' and operate normally.
(3) RELEASE: When RT-Sensor is working normally.
C. 'd1' ERROR
: It happens when D-Sensor is OPEN or SHORT.
(1) LED DISPLAY: Shortly flickering(0.3sec.) 3 times.
(2) CONTROL: Return to next limit defrost time (40 min)
(3) RELEASE: When D-Sensor is working normally.
D. 'DR' ERROR
: It happens when the system senses door opens more than 1 hour.
(1) LED DISPLAY: Shortly flickering(0.3sec.) 4 times.
(2) CONTROL: Delete function relating to door switch sensing
(3) RELEASE: When sensing close from door S/W.
E. 'F3' ERROR
: It happens when Defrost Heater off after 60min.
(1) LED DISPLAY: Shortly flickering(0.3sec.) 5 times.
(2) CONTROL: Skip the step 'PRE-COOL' of Defrost Mode.
(3) RELEASE: Defrost Heater off by D-Sensor.
※
When pusing 'TEST KEY' on the main PCB,
LED is long(1.0sec.) flickering several times.
ex. 'Forced Defrost Mode:' long flickering 2 times
