  1. It is disturbing to see how many people have this problem. We just recently had to take ours apart and clean the roller-looking things because they were DISGUSTING. When we turned it back on, it’s stuck on C1/54 and won’t come on. I sure wish someone would address this problem because now it’s obvious that we aren’t alone.

  2. Looks like a common problem with Samsung ACs I also have the same issue will try their service department as is still under warranty.
