This refrigerator will turn on the dispenser light and open the flapper of the ice bucket about every 12 hours even through the ice maker is "turned off".
I have disconnected the water feed since when this event happens, the water may also run by itself. I pulled the plug and this did not stop the problem. About a year ago, I replaced the flapper since the spring was broken. The refrigerator does control the temperature which is set at -4f and 34f. I would believe that the control board appears to be the problem. Please confirm and also is there a way to reset or check this board and is this the display that you use to set for water and temperature? Is it possible that the micro switch that you use to activate the water/ice to fill the glass could cause this problem?
