A:Answer Wheels are used for moving the fridge. They can be positioned so they don't move. BUT, a full fridge is so heavy, you will not have this problem!! I would not worry about it.
What should you worry about? Well, my condenser is full of ice. When I search this problem on the internet, I have learned that the fridge cannot be easily repaired and a fix would be at least $600. This is COMMON problem. It is a product defect. I do not recommend Samsung refrigerators regardless of the reviews.
ONE YEAR WARRANTY from Samsung says it all. This product will break.
