Hello, sorry to hear about your issue. I too, as well as many others have had this too. First, I can tell you Samsung may reach out to you but it’s just a waste of your time unless you have a loss of money. They have told me the knobs were designed to turn easily. I hope you read back from the beginning of this thread. There is an easy fix described many times with some rubber grommets you can get at a Home Depot. I wound up doing this because this Crappy Samsung company is waiting for someone to die I guess and will not address this problem. I know this sounds stupid and I don’t like recommending this because I shouldn’t have to. It does work. When these grommets are put on the knob has to be pushed in with more effort and turned. It’s not easily turned on. I have not had another issue since doing this, except now I hate anything with Samsung’s name on it. These are pretty inexpensive. When I bought mine they were 99 cents apiece. I hope this helps. Good luck, enjoy your house, be safe.
