There is a thin layer of frost on the back wall of the freezer.
ok it sounds like you ahve a defrost problem , we see this allot on these. you probably need a dfrost heater. i'll look that up for you and be right back thanks Bryan
Where do I get the part? And, about how long will this take?
Yes, we put the back panel on. I noticed it has a light layer of frost on it like before, though. We will try to take the panel off today or tomorrow and let you know what the coils look like.
