I have a kitchenaid side by side refrigerator that is approximately 7 years old. It has always ran perfectly. We noticed the ice was kind of melty this morning and sure enough things are defrosting. I emptied the freezer and took off the large metal panel that covers the fan. The fan is running fine and there is no ice anywhere. I also took the cover off the back, there isn't a significant amount of dust cause I clean it pretty often. The fan in the back is also working fine. I unplugged then plugged it back in and I thought I heard a click come from that large black tank (compressor?) but when I repeated the unplugging process I didn't hear anything. I am in the process of getting divorced so I am basically on my own with this. I can't really afford a service guy although it seems that is what I may have to do. This sucks, good thing its so cold outside! Any suggestions would be greatly appreciated. Thanks. :(

Sound like the compressor is not running ,remove black cover near the compressor you will find a start relay and overload.a relay is a device that start up the compressor.You can check this by prying it out. Shaking it to see if is broken inside (it will rattle)if it bad. Unplug the fridge first.
