Please consult your owner’s manual. If too many bottles/cans are put in at once or the door has not been closed tightly, the unit will display the “HI” signal in the display panel. This is normal, please wait 5 minutes after you close the door and “HI” will disappear.
It is normal that the cabinet shows “HI” or “LO” from time to time. If it occurs frequently or lasts for a long time, you can restart the unit by unplugging it. If the problem occurs once again after restart, please contact customer service.
