As you can see from the model and age of the fridge, it is pretty old, it think. Well it stopped cooling and freezing, my icecream is melting and that is making me sad 
, How do I go about seeing what is wrong with it? I believe you can all help me and it would be greatly appreciated
Remove back freezer panel and check frost pattern, if only partially frosted, you have a refrigeration system problem for a pro. to fix. If no frost, check your compressor. If not running and all fans running, you may just have a bad start relay.
I would check your three compressor pins for ohms. If ok, just replace the start relay. Click on your model # to get it.
