My kenmore side by side fridge won't get cold. The freezer has some ice built up on the back wal and keeps things cold as if they were in the fridge side. The fridge side doesn't keep anything cold at all. What could this problem be?

Oh yes! We had this problem. The first time we called a repairman and he was able to fix it. The second time we did it ourselves since my husband watched! IF you can take the front panel off the face of the fridge ( the bottom screen like thing) there is a place that you can turn down the temperature I think to the left, but anyway you turn it until you don't hear it running. YOu can take everything out of the freezer and use a hairdryer on the back of the freezer ( inside where you feel the ice behind it) keep thawing it out until you don't feel anything. Then you can turn up the thermostat again and it should start circulating the air back to the refrigerator side. Ours seems to do it when we have too much in the freezer. Seems that it freezes it up and then the air can't circulate to the other side. Hope this works for you. We have done it many times and it save us $$$$.
