I got a fridge from my mother. It is a Jenn air. It is probably 7 years old-relatively new. Anyway, they got a new frige and I got their "old" one. They said that the ice cream has been soft lately and the ice machine doesn't freeze anymore, but aside from that it is in working order. A family member delivers the frige to me and it is in the truck on its side... to get it out, we had to actually turn it up side down for a minute. I let the frige sit, unplugged for 6 hours. I then plugged it in and let it run overnight. I woke this morning to find that warm air was blowing out of both the frige and freezer. I unplugged it again and will try to plug it in again later today.

What could be the issue? How much should I expect to pay for someone to fix?
