Fridge has not been getting very cold on the door section to the point we moved the milk to the inside of the fridge because it was spoiling within 4 days.
I went ahead and opened the back up and the coils were pretty dirty, got them all clean and put a thermometer on it to keep track, I turned the extra freeze feature or whatever it's called which is set at 33° and the lowest it has reached is 47°, the lower fan seems to be turning on.
I read on another thread that it has a second fan inside. I also read someone had and issue with the upper sensor was giving wrong results due to ice build up.

Is this where I need to start to try and fix it?

Looks like temps dropped a bit more overnight but still far from the preset temp

Yes, if you don't hear the upper fan running, then that's the problem.

FIXED - RF323TEDBSR/AA Samsung refrigerator not getting cold

I have a sumsung RF323TEDBSR/AA and the refrigerator side is not getting cold, the freezer works great. I pulled the shelf’s out and the back off and the coil isn’t freezing up. My next step was going to be to check the damper, where is it located?

The upper fan motor comes with the evaporator cover and new sensor as well:

Hi Jake. Appreciate your response.
So it slowly creeping down to what it should be, maybe it was just the dirty coils.
Is it common to take so long to reach the set temp?
I started to monitor Temps at 1pm yesterday before cleaning the coils and the temp was 57.4, now at 11am it's at 36.7.
What do you think?

It should take about 4 hours with the doors closed to get to the right temp. but if you have a lot of traffic with door openings it will take longer.
