Frigidaire side by side fridge freezing

Fridge side has been freezing food and water lines to water filter.
I read a few replies from Gene on another post Stating to adjust freezer to 4 and fridge to 1. This did help but what is the problem and how can I fix it? I did hear the door closing and confirmed with my hand that it stopped blowing air in the fridge from the small vent from within the fridge side. Any help would be Appreciated.

You out there Gene?

Hi,

I have seen a few bad damper controls on these models, 241600902

Are there any specific tests I can do before I buy the part?

If the temperature control adjustment helped to eliminate the problem then there is nothing wrong with the refrigerator.

Gene.

So leaving the settings at 4 freezer and 1 fridge is the solution?

I will say yes as long as it works fine.
