I had this refig for 1 yr and 4 months. Last week I discovered the freezer ice colder, and refrig department warm last week. I checked it out, and found the bottom opening on the lower left side the coils were snow freezed up, and no cold air blowing from the left top vents. I checked the damper for operation, and it worked. Matter of fact, no air at all. I unplugged refrig ,and use a hair blow dryer to defrost the lines. After defrosting manually, started the refrig and worked correctly.
Today, Tuesday,Nov.27,2007, the same problem. Refrig warm and no air blowing at all from the top left vent. I click the light button five times to put refrig in defrost mode. I heard the compressor kicked off. Waited an hour, same problem. I pulled the refrig out and checked inside behind refrig. No dust or anything frozen. I looked inside the refrig on lower left side inside vent holes, and coils snonwed as mentioned above.
What could be causing this problem or what is the problem and how to fix?????? By the way, when things didn't work properly, I noticed the h20 dispenser didn't despense any water. I mean no water! I hope this is enough info to help me with my problem. I did the same thing(hair blower trick) like last week, and its working fine again.

That is the model number on refrig

Try turning frig. off for 24 hrs. You may still have ice in ducts you don't know of. As long as freezer coils aren't badly frosted or frozen over. Other wise you may also have a defrost issue.
