TROUBLE SHOOTING
2) If any connector is not connected properly, replug it firmly.
3) Press and hold the button on the power board for 3s 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 the icemaker 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
pin2 and pin 3 of CN4. 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.
