SERVICE MANUAL
Model:
Symptom:neither displaying nor starting when powering on
Check:
1) Check if the power supply is connected properly.
2) Remove the main control panel and examine its back side carefully to see if there are
solder skips or open soldering;
3) Check if the connector of the freezer door hinge is connected properly.
4) Verify the display panel to see if the refrigerator is in OFF state. If so, press and hold the
button on the power board for 5s to turn it on.
Solutions:
1) If there is dry soldering or open soldering on the control panel, resolder it with an electrical
iron.
2) If any connector is not connected properly, replug it firmly.
3) Press and hold the button on the power board for 5s to turn the refrigerator on.
Symptom:poor freezing effect accompanied by loud noise
Check:
1) Check if there is apparent abnormal sound in the freezer storage compartment. Remove
the fan cover plate, close the refrigeration air door, and check if the freezer fan is operating
normally. (The fan does not operate when the refrigeration air door is open. Please first
eliminate the possibility of improper installation of the door on-off)
2) If the freezer fan does not run, remove it and check if its connector and the cabinet
connector are connected properly. Test if there is approximately 12VDC voltage across
pin1 and pin 3 of CN2. If there is no 12VDC voltage, the main control panel can generally
be determined to be malfunctioning. If there is 12VDC voltage, the freezer fan can
generally be determined to be malfunctioning.
3) If the fan rotates abnormally, the fan is malfunctioning.
Solutions:
1）If there is apparent abnormal sound in the freezer storage compartment, check if the fan
base is firmly fixed, if the fan vanes are installed properly, and if they intervene with the
wires. If any of these problems is found, please remove the fan and reinstall it properly.
2）If the fan connector is not installed properly, disconnect the terminals and reinstall the
connector。
3）If the main control panel or the fan is malfunctioning, replace the malfunctioning one with a
good spare part.
