Please help fix my fridge before a house full of guests get here!

The refrigerated side of our refrigerator is too cold. We have it turned down to "1" and things will freeze if they are in the back of the fridge, in the crisper drawers, and on the shelf above the meet drawer. Vegetables are especially prone to freezing - lettuce, carrots, cucumbers, etc. I can not keep vegetables in the fridge without them getting ruined in a day or two. We took the panel off and cleaned all of the coils and under the refrigerator and it did not help. The freezer is set on 3. I have 10 people coming here for the holidays and a fridge that can’t hold food - please help!!
Thank you.
