Hi Russell, We have exactly the same problem with our 3 year old Samsung side by side fridge freezer. We contacted Samsung who told us to turn it off for 24 hours with the doors open. This we did, but it worked OK for about 3 weeks, then same problem. Samsung didn't want to know as it was over 2 yrs old. We still have the problem. I'm trying to sort it out today. If I have any luck, I'll let you know.
