The fault indicates that the refrigerator refrigeration is normal, which may be caused by the fault of the air duct system or the set temperature of the refrigerator temperature control knob is too high. Open the refrigerator door and check that the setting value of the refrigerator temperature control knob is "medium". At this time, you can pull out the drawer door of the refrigerator, press the button switch of the refrigerator, and listen to whether the fan motor of the refrigerator is running.

If there is sound, check the air door control of the refrigerating room, cut off the power supply, take out the fresh-keeping tray, remove the air door cover of the indoor panel of the refrigerating room, and then plug in the power supply. If the damper does not open or close, there is something wrong with the circuit control board or damper.
