I have a Samsung RF266AEPN French door refrigerator. About

This answer was rated:

I have a Samsung RF266AEPN French door refrigerator. About three months ago we noticed that the unit buzzed whenever the doors were closed. We also noticed that the ventilation holes in the back of the refrigerator section were blocked by ice build up and the refrigerator itself was at 45 degrees despite the temperature display saying "34". We unplugged the unit and kept the doors open for several hours or overnight until the ice is melted and then plug it back in -- it seems like we have to do this every 2 weeks or so. What do we need to fix to get it working normally without us having to defrost the whole thing all the time?
Hello my name is XXXXX XXXXX you for choosing our service.

The ice that you are seeing is that like white frost? Do you have water under the drawers also?

Customer: replied 2 years ago.

The ice looks more like clear to milky ice, thought it's a bit difficult to tell because it's covering white Styrofoam. When this first happened, I pulled out the produce drawer on the bottom and there was a significant amount of water but I had chalked that up to my kids not holding their kids up to the water dispenser properly (it's inside), but I just went and looked again and there is water under the bottom drawer but it's more towards the back.

Thank you, XXXXX XXXXX question, have you ever removed the rear wall in the fresh food section?

Customer: replied 2 years ago.

No, I have not.


I understand, I will get that sheet for you and put it in with the answer so you will have it. Give me a few minutes to get that and type.

The first thing you will want to do is remove the rear inside wall in the fresh food section and clear out the ice. There is a file I have uploaded for you just below to show you how to get in there, also scroll down to the last picture. Where that arrow is pointing is a drain. You will need to clear the ice from there as well. That will help some. Below is a link to a part that you will need to replace. Its a sensor, and that will take care of the cooling part as well as the frost/ice.

Below is the sheet to help you get in there. Its not exact but it is very close...


Once you get the ice cleared and the sensor replaced which is attached to the coils behind that panel everything will return to normal again.

If you have questions about my answer please click the "Reply To Link" I will be happy to explain anything that is not clear.

Hi Barry, I took a look at the sheet and I am guessing it cuts off, because the last step is to remove the evaporator and that's it...nothing comes next and it doesn't show the part you described anywhere.


Hi there Nicola.

There are 2 pages, the last picture on the 2nd page is where the drain is. Skip everything else, That sheet is to help you get to the drain you do not need to remove anything but the rear fresh food wall.
