This genuine replacement shutoff arm spring is for refrigerator ice makers. It applies tension to the ice maker shutoff arm to hold it in place so that the ice maker will stop making ice when the ice bucket is full. If your ice maker continues to make ice when your bucket is full, you may need to replace this shutoff arm spring. This part is less than 2 inches long, and is made entirely of metal. Be sure to disconnect the power or the water supply to your refrigerator before completing this repair.
