Fridge was warm and freezer still frozen - same story as everyone else!

I had called a repairman and was told that the part alone would cost me $300 and, when he had finished diagnosing everything, he told me to buy a new refrigerator based on needing a "computer". I paid him his charge to come out and even considered buying a new fridge, but we couldn't find one that would fit the narrow space we have the way this model does. (We also have a funky seal that we will maybe replace sometime and I have since purchased the actuator pad.) I read all the posts before I decided we could do it. It was easy with all the instructions people included. I did have a bit of difficulty fitting the new plastic covered module into the space the old one was in, but with it tipped at an angle I was able to screw everything back in place. My only problem now is that the refrigerator is very cold (30-32) even with the temperature control near the bottom setting - but nothing in the fridge is frozen. My husband and I are not real handy and we always fuss at each other when we do this type of thing together, but we did okay because anytime we had a question I would pop back to the computer and read what others said about performing the repair. I would not have even attempted this without all the helpful repair stories. This is a great help - and I almost spent $1,200 on a cheap new fridge. Even though I paid the guy $75 and purchased this part with next day shipping, I figure I saved $1,000! It has been four years since I had this same part replaced under a maintenance contract and I was completely ignorant to how much they would have charged me at the time. If I get another four years out of this unit I will be happy. I also might just keep fixing it with the help of PartSelect! Thanks everyone for your help.
