Other fault phenomena and maintenance methods
(1)
The refrigeratordoes not work. (The whole machineis not working, with the
compressor not started, the display panel not illuminatedand the LED lamp OFF
when the door is opened.)
a.
Check whether the refrigerator plug is properly plugged in; whether the
socket is electrified; and whether the socket voltage is normal.
b.
Cut off power supply, remove the electrical box cover, observing whether the
terminals are properly connected, reinsert the terminals, and then power on
the system to observe whether the refrigerator can work normally.
c.
Cut off power supply, change the main board, insert the terminal well, and
power on the system to observe whether the refrigerator can work normally.
(2)
The compressorcannot start. (Other devices are working normally)
The compressor shutdown duringthe normal operation of the refrigerator does
not belong to this type of failure. Be sure to wait for at least 5 minutes before
starting the compressor again in the case of compressor shutdown. During the
following maintenance operations, if a power failure occurs, please wait for 5
minutes, and then power on the system to observe the compressor working, or
wait for 5 minutes after the system is powered on to observe whether the
compressor can work normally or not.
