Hi,
The quick answer is to turn the water off to the refrigerator so it quits making until you get it fixed.
If your fridge has the control boards in each side of the freezer cabinet that controls the icemaker, then you have a failed board.
If you have a standard icemaker with the metal shutoff arm then you have a failed motor module in the icemaker.
You can remove the icemaker and unplug the wiring connector from it so you can leave the water on to the dispenser
