Freezer is working but having frost, Fridge is not cooling enough.
My Samsung French door RF220NTASR is not cooling enough. Freezer is set to medium and is quite cold, I do not know what temperature it is at but things are staying frozen. I am noticing a bit of frost and ice at the bottom and on containers. Fridge compartment is not cooling enough. Things are cold but not as cold and is causing food to go bad, my milk was all curdled in 4 days. Usually it used to last for 7-8 days without issue.
The fridge is also making a noise, a part of it I think is coming from behind and is a loud noise of something spinning, the noise can be heard in the next room when quiet.
Not sure if the cooling is related to the noise the fridge is making but think they are connected. Please help to isolate the problem so that I can replace the part which is broken.
