Ge refrigerator Model GSS25LSWASS The Dispenser Interface model WR55X10708 Light goes on and off we cant get water or Ice. I thinking the dispenser motherboard needs replaced.I tryed unplugging it and that didnt work. Can you buy just the mother board or do you have to get the key pad with it in one part. How do you get it apart? I tryed pulling off the trim piece that surrounds the whole water dispenser area. It doesnt want to come off easily and I dont want to break it. It needs to come off to get the interface off I believe. If I get it off hows does interface come off.Thanks Harold
