@jcboy,
I had all of the problems you have had with your Samsung, but I had a GE. That 2 year old monster broke down often and the techs were puzzled. I wrote to GE and complained but they ignored me...........for a while. Remarkably, GE called me later and offered several options, the last one was they would buy my refrigerator and I could call it a day. I took them up on that and they paid me what I originally paid for that monster........I was shocked, I actually bought another GE, practically the same thing French doors, slide in freezer...and it's been great for the last 7 or 8 years. I thought I would never buy another GE fridge, but I did.
You should write to Samsung, and tell them your problem. If loads of people are complaining online, they will need to do something to fix the problem. I'm sure they are aware of GE's fridge problems, maybe they will buy yours?
