Hi I'm John I will help you with the fridge problem.
Is the freezer cold enough to have hard ice cream ?
At the top left in the fridge is a damper door it could be frosted up.Remove the cover and see if that damper is open or closed.
This is the damper control ,Frost build up is usually the problem.
Check that and let me know if thats the problem please.
Remove cover inside frig at rear wall top with screw driver. Remove Phillips screws holding unit in place. Unclip connectors ,and replace in reverse order.
The part is where the cold air enters the fridge from the freezer.
