Our Samsung fridge is not cooling properly. Ice can be seen behind plastic panel at back of fridge. I'd like advice on what might be cause of problem, and how to approach diagnosing and fixing it. I am thinking it may be problem with airflow, or proper drainage during defrost cycle, or defrost element itself not functioning.
Also, freezer compartment seems to build up a lot of frost... is this related to fridge not cooling?
I'd like to find a pdf of the service manual if anyone has it.
Thanks so much!
