My GE water dispenser stopped working and as it was still making ice (emptied ice tray to verify) and could hear solenoid when water button pushed. I did not have any weed wacker line but I did have some 16ga stranded wire. I cut about ten inches or so, stripped about an 1/8 inch off one end and 3 inches off the other end. Ran it in the supply line and hit the ice. I untwisted the longer end and using a hair dryer on high heated the bare copper which transferred the heat up the wire to the shorter bare end. Let the wire sit for a few minutes then repeated and ice was gone. Water dispenser froze up again and in the end it seemed to be related to placement of ice packs on the freezer door which caused my issues. I also got the little syringe to thaw the ice out but have not had any more problems after moving ice packs. I did find in my research that care you be used with a hair dryer as it seems it’s possible to warp the plastic parts of the ice dispenser.
