My Frigidare Upright Freezer not freezing

My upright frigidare, model # FFU20FC4AW2 has stopped freezing. It is blowing warm air, lights are on, motor running but no cold air. I am not sure where to start in fixing this problem. Please help.

Thanks,

Adam

Hi, did you get your freezer working? I have a whirlpool upright freezer that is doing the same thing. No one has replied. So just checking you can email me back at talktomeh@yahoo.com THANK YOU FOR YOUR HELP
