Description
Solution
E1
When the temp. in UPPER zone is 4F (2C degree) higher than LOWER zone,
E1
display on panel.
With the temp. changes, temp. in UPPER zone is lower
than LOWER zone, E1 will disappear automatically. So,
just wait for about one hour and check again.
F1
1.
When the evaporator temperature is lower than 0F (-18C degree)
F1
display on
panel
2.
F1
meaning the fridge is at defrosting mode.
3.
During DEFROSTING period, evaporator fan is operating but compressor stop.
4.
After evaporator temp. is higher than 39F (4C degree),
F1
will disappear
It’s normal, nothing need to do. Wait for 3 hours and
check again. Or, turn OFF the power, open the door and
wait for 3 hours, then check again.
F2
1.
If compressor keeps operating continuously for over 8 hours, the fridge will
automatically enter DEFROSTING mode and
F2
display on panel
2.
F2
meaning the fridge is at defrosting mode.
3.
During DEFROSTING period, evaporator fan is operating but compressor stop.
4.
F2
will disappear after 20 minutes
It’s normal, nothing need to do. Wait for 30 minutes and
check again.
C1
C1
displaying on panel, means sensor in UPPER zone is open-circuit. Compressor
stop operating and no cooling
Need engineer to check
1. Socket/plug with UP mark in PCB is bad connected.
2. The sensor is damaged, need to replace it
3. Repair or replace the PCB
C2
C2
displaying on panel, means sensor in LOWER zone is open-circuit. Compressor
stop operating and no cooling
* This does not apply to SINGLE zone models
Need engineer to check
1. Socket/plug with DOWN mark in PCB is bad connected
2. The sensor is damaged, need to replace it
3. Repair or replace the PCB
C3
C3
displaying on panel, means evaporator sensor is open-circuit. Compressor stop
operating and no cooling
Need engineer to check
1. Socket/plug with PTC mark in PCB is bad connected
2. The sensor is damaged, need to replace it
3. Repair or replace the PCB
U1
U1
displaying on panel, means sensor which is in the UPPER zone is short-circuit.
Compressor stop operating and no cooling
Need engineer to check
1. The sensor is damaged, need to replace the sensor
which is connected to UP socket/plug in PCB
2. Repair or replace the PCB
U2
U2
displaying on panel, means sensor which is in the LOWER zone is short-circuit.
Compressor stop operating and no cooling
* This does not apply to SINGLE zone models
Need engineer to check
1. The sensor is damaged, need to replace the sensor
which is connected to DOWN socket/plug in PCB
2. Repair or replace the PCB
U3
U3
displaying on panel, means evaporator sensor is short-circuit. Compressor stop
operating and no cooling
Need engineer to check
1. The sensor is damaged, need to replace the sensor
which is connected to PTC socket/plug in PCB
2. Repair or replace the PCB
No Code
After the temp. is lower than 32°F (0C degree) or higher than 69°F (20C degree),
the buzzer will alarm and remind user need to pay attention.
