Ice maker is posessed (by 3 users)

The ice maker quit producing ice. I removed it to find the “head unit” filled with ice and frozen up. Thawed it good, blew it out (over two days). While reinstalling it water would come out the fill tube AND the dispenser on the door. Found ice in the terminals, hair dried them, reinstalled. Still no ice and when getting water out of the door water dispenses out the fill tube.
