Which numbers give the coldest setting in the fridge section of the Frigidaire Refrigerator

Higher numbers make for colder temps.

Well, mine is set to 1 and it freeze everything in the fridge! I'm going to try the opposite

If your refrigerator section is not cold enough at the normal setting you may have a problem.
If you can't find enough information at the link below resubmit your question and include the model number. It should be inside the refrigerator section. It's usually on the upper right wall.

six is the coldest setting 1 is the lowest

6 is coldest, start w 4.then raise or lower after 24 hrs

7 is coldest

if your freezer can make ice and the ice is dry, the problem is simply air flow into the refig section. A very common cause for a service call that wasnt needed for reefers is the settings. One setting OFF 1-10 usually, operates the compressor. The remaining setting will say , for colder freezer or similar, It opens a little flapper door between the freezer and the fridge section. If you set that one to max or coldest freezer it will actually starve out the fridge section for air ,and you get a cold freezer and warmer box! It happens everytime someone has the problem , its too warm! they peg both controls to coldest! The compressor will coll the freezer sufficiently even if set to 1 and the fridge should be cool too if the setting isnt pegged to coldest setting thus closing down fridge air and making the freezer colder which isnt ever required!

the higher the number and alphabet the colder it will be

10 is the coldest. Hope this helps you:) I keep mine at 6 and its great.

lower the number, warmer the fridge.
setting 1 - warmest
setting 5 - coldest

this is the same for all fridges
