Per the suggestion to the question Samsung RF266 refrigerator not cooling - Fan making noise I completely defrosted the refrigerator. The issue went away for a few days, but re-surfaced again. So I decided to disassemble to refrigerator understand the root cause of the problem. Yes there is Ice build up. Here are some images.

As you see in the image below. There is a good amount of ice buildup.

What are any suggestion to try fixing the issue? How can one test to verify if the fan is still working.

  • Can you operate the fridge with the covers off after the ice melts? It should be apparent if the fan is working or slipping on the shaft.

  • @JPhi1618, what I observed is when the door is open the fan stops. I know this because when the ice was present the fan noise is present (doors closed) and when the door is opened the fan stops. Do you know how I can force the fan to operate when the door is open?

  • If there is not a lever on the door that pushes a physical switch, there is a magnetic reed switch in the door frame somewhere. A magnet in the right location would make it think the door was closed (you might have to flip the magnet - north/south could make a difference).
