2. The input voltage is too low to reach the
minimum starting voltage required by the battery
protection, resulting in the refrigerator can not
start. Reduce the starting voltage gear can solve
the problem.
Minimum motor speed error, the compressor is
over-loaded, and the motor cannot maintain
its minimum speed of 1850 rpms.
E4 Error Code
1. Make sure to turn o the machine and
wait for 5 minutes before turning it on again.
If the compressor starts and then stops a
few seconds later, it is an E1 fault, and you

2. The compressor will break down at ambient
temperatures above 55°C. Try to avoid using the
refrigerator at high ambient temperatures. Make
sure there is enough space outside the compressor
cover to dissipate heat
(more than 5cm on the left and right sides and 10cm
space on the front air outlet).
Check that the cooling fan terminals are connected
tightly. A non-functioning cooling fan will result in the
compressor being unable to dissipate heat and the
temperature will rise.
