Broken

When we bought our house, my cousins sister-law gave us a wonderful on top refridgerator, freezer on the bottom model . Yesterday we opened up the fridge and the milk was spoiled, lunch meat ruined, etc. What was funny was that the freezer was working just fine. We have tried a couple of things to get it working again and were down to one more idea. Say a prayer that it works because shelling out 1000 bucks right now is not so hot before christmas :(.
