We have a Kenmore Elite frost-free side by side refrigerator with ice maker. It's 2 years old but for the past 2 year+ we've been having problems with the freezer building up frost around the inside, and then the refrigerator doesn't get cold. I have to unplug everything, take the shelves out of the freezer and then blow-dry it sometimes twice a month, and then the refrigerator gets cold again.
I had Sears while under warranty come in twice they replace something and 3 months later the same thing happened, I had to call an so called expert to change something else first cost me $75.00 and the second time $150.00 and still have the same problems.
The seals around both the freezer and the fridge side are fine, so that can't be what's causing the problem. I've removed any dust buildup both under and on the back of the fridge.
This is the model # 106 567 03 500
Serial # SS 3734874
I read some advise that when you open the door and press on the lite switch the fan is supposed to stop? Or something , nothing happen when I do that.
Thanks
I just wish there was a place where I could take it and just dump it in front of sears' door.

It sounds like the defrost timer switch. I had a side by side that would eat these switches for breakfast. Very common part to keep failing. The next "expert" you have fix your fridge I would suggest that you personally watch what the guy is doing and have him explain what he's doing as he does it. That's what I do and I know they don't like it, but it's my way or the highway when it comes to parting with my money for repairpeople. Have the repairdude use a Kenmore replacement part and not a generic part. And if the same thing happens again with a genuine Kenmore part, I'd call up Sears and complain big time.
