Mount E Blade Serial What's Wrong With My Bottom Mount Freezer - Freezer Works, Fridge Not Cooling?

What's wrong with my bottom mount freezer - freezer works, fridge not cooling? - mount e blade serial

I have a Kenmore model # 795.65209402 freezer below. The freezer freezes, but can not be cool in the fridge. There was no air in the freezer to the refrigerator. The fan does not work there. I think the engineers concluded that there is no power to the fan (the one with the information) came from. Well, I waited back at us and said he did not know whether it is a part of the update. Well, I did some research on and found a few parts. I think the problem is a sensor (Part # 6615JB2005C to a part of Sears) list. It costs $ 12.99, but not within 60 miles from where I live. I thought to get the fan, fan motor and the sensor (about $ 50.00 total online) by Sears and the replacement of shit by myself. Who knows if anyone can fix this problem (this is a DIY project is this?)?
