GSD3200G00WW ice cube maker and door froze. Can't find my manual. I toggled the switch in back to "O" from "I". What does that switch do and where should it be? The ice cube maker was all frozen. I think the water dispensing door was also frozen and no water. Now water is running. Reoccurring problem has been the ice dispensing flap doesn't always close and creates melt down and refreezing. Please advise. sjbrodbeck@frontier.com
