My refrigerator is 4.5 years old, a side by side. The freezer is fine but I find this morning that the refrigerator side is not very cool. It was in the setting in the middle of the range and I have to be careful usually that my eggs don't freeze. The light is on.

Any tricks for diagnosing this? Turn it off and on again? Unplug? I've tried adjusting the temperature cooler and will wait a while to try it, but I have a sneaking suspicion that won't do the trick.

This is a Kenmore Coldspot. Don't see a model number beyond that.

(I've given this a general title since other appliances on the fritz might appreciate being mentioned here also. And now I'm going to get my camping cooler and buy some bags of ice.).
