• When the temperature detection fails, the display shows an error message
[ F1
°
C ], it means the NTC function is defective, which can only be repaired
by an authorised repair centre.
• When the fault indicator flashes, it means the DC power supply voltage is
lower than the currently set "Battery Voltage Protection" gear. The battery
needs to be charged or set the "Battery Voltage Protection" gear lower for
using continuously.
• The flashing red light indicates an error message during the operation of the
refrigerator. The frequency of flashing depends on the type of error. Each flash
will last for a quarter of a second, and there will be a pause after a series of
flashes, as shown in the following table. The error indicator will flash
repeatedly every 4 seconds.
Frequency
of Flashing
Fault Possible
Causes
1
Operating voltage
too low
Voltage is lower than 9.6V and needs charging
Fan current too
high
2
The current in the fan load circuit exceeds 1A
The pressure difference in the refrigeration
system is too large (>5bar)
3
Compressor does
not work
Compressor
rotational speed too
low
The refrigeration system is overloaded, the
motor cannot maintain the minimum speed of
1800 rpm
4
5
Part of circuit
overheated
The ambient temperature is too high or the
ventilation is not good
• Note: In case of the above 2, 3, 4, and 5 failures, you can switch off the device
and restart it after sufficient time.
• If the fault persists, you need to contact an authorised repair centre.
