I have a Kenmore SidexSide Cold Spot Refrig/Freezer. I can hear the fan running but both the freezer and refrigerator sides lost cold air. (I'be been cooking all day!). Anyone have suggestions? It's only four years old but the warranty is out. Thank you.

Could be a lot of things. Which fans do you hear running? They have evaporator fans inside and some have condenser fans usually at the bottom of the refrigerator. Do you hear the compressor trying to run? Does it come and hum for a couple of seconds and then shut off? You could have a bad thermostat, defrost time, could have leaked out the refrigerant or even the compressor could be bad. Usually Sears has a 5 year warranty on compressors. Sorry I can't be more help.
