Kenmore Refrigerator: not cooling properly

If your refrigerator or freezer suddenly stops cooling and the freezer does not freeze, we have several solutions for you. If you hear a clicking sound coming from the back of the fridge / freezer, the problem is most likely with a compressor; it is overheating or is not getting the proper power and will not start. A compressor is a component of a refrigerator that allows it to cool. If this component does not work properly, your refrigerator will stop cooling. In most cases, the compressor is not a faulty component. Your airflow fan for the fridge might be out. Open ONE of the refrigerator doors and then push the button at the top of the door to make the light go off. Put your hand in front of one of the holes in the back of the middle of the fridge and see if there is air flow. You might have to pull everything out of the fridge, remove the shelves, unscrew and remove the back panel of the fridge and then push the button in to see if the fan is turning. While the panel is off, you will also see the evaporator (cooling) coil and fins. They should be at least half 'frosted'. You can shut the fridge doors for a few minutes and see if they're frosted. If they're frosted, and the fan isn't turning, that's your problem. Those coils could also be iced over to prevent air flow. That would be an issue as well. No frosting or cooling of the fins at all means you may have a stuck refrigerant diversion valve (which switches refrigerant flow between freezer and fridge). If everything is working correctly, you should feel the cool air coming in. If so, the issue is resolved. Remember to clean the refrigerator coils every 6 months to avoid this problem in the future. It is always a good idea to arrange a professional visit and check the functioning of the refrigerator to prevent future problems.
