Description
Solution
E1
When the temp. In the UPPER zone is 4
°
F (2
°
C ) higher than the LOWER zone, E1
displays on the panel.
With the temp. changes, and temp. in the UPPER zone is
lower than the LOWER zone, E1 will disappear
automatically. So, just wait for about one hour and check
again.
F1
When the evaporator temperature is lower than 0°F (-18°C ) F1 displays on the
panel
F1 meaning the refrigerator is at defrosting mode.
During DEFROSTING period, evaporator fan is operating, but the compressor
stopped.
After evaporator temp. is higher than 39°F (4°C), F1 will disappear
It’s normal; nothing needs to be done. Wait for 3 hours
and check again. Or, turn OFF the power, open the door
and wait for 3 hours, then check again.
F2
If the compressor keeps operating continuously for over 8 hours, the refrigerator
will automatically enter DEFROSTING mode and F2 displays on the panel
F2 meaning the refrigerator is at defrosting mode.
During DEFROSTING period, evaporator fan is operating, but the compressor
stopped.
F2 will disappear after 20 minutes.
It’s normal; nothing needs to be done. Wait for 30 minutes
and check again.
C1
C1 displaying on the panel means the sensor in the UPPER zone is open-circuit.
Compressor stop operating and no cooling
Need an engineer to check
Socket/plug with UP mark in PCB is badly connected.
The sensor is damaged, need to replace it
Repair or replace the PCB
C2
C2 displaying on the panel means the sensor in the LOWER zone is open-circuit.
Compressor stop operating and no cooling
* This does not apply to SINGLE zone models
Need an engineer to check
Socket/plug with DOWN mark in PCB is badly connected
The sensor is damaged, need to replace it
Repair or replace the PCB
C3
C3 displaying on the panel means evaporator sensor is open-circuit. Compressor
stops operating and no cooling.
Need an engineer to check
Socket/plug with PTC mark in PCB is badly connected
The sensor is damaged, need to replace it
Repair or replace the PCB
U1
U1 displaying on the panel means a sensor which is in the UPPER zone is short-
circuited. Compressor stops operating and no cooling.
Need an engineer to check
The sensor is damaged, need to replace the sensor which
is connected to UP socket/plugin PCB
Repair or replace the PCB
U2
U2 displaying on the panel means a sensor which is in the LOWER zone is short-
circuited. Compressor stop operating and no cooling
* This does not apply to SINGLE zone models
Need an engineer to check
The sensor is damaged, need to replace the sensor which
is connected to DOWN socket/plugin PCB
Repair or replace the PCB
U3
U3 displaying on the panel means evaporator sensor is short-circuited.
Compressor stops operating and no cooling.
Need an engineer to check
The sensor is damaged, need to replace the sensor which
is connected to PTC socket/plugin PCB
Repair or replace the PCB
No Code
After the temp. is lower than 32°F (0°C) or higher than 69°F (20°C), the buzzer will
alarm and remind the user needs to pay attention.
Normal, nothing needs to be done.
