Ice Maker does not stop making ice and icecle hangs from it.

I have whirlpool side by side refrigirator freezer model No. GD25DIXHS00 8 years old. The ice maker keep making ice even when the ice maker switch on freezer wall is turned to off position and water over flows and there are icecles on the freezer cabinet wall and also hanging on ice maker and on shelfs under. The icemaker buket gets full and ice overflows. I am not sure if the sensor on the on-off switch is gone bad and does not stop the watrer and shutt the ice maker off or it’s something else. Please see the attached 2 pictures. Please advise. Thanks!
