Between settings 1-9 what number should my refrigerator be set at?
You should set it somewhere in the middle, so if it is labeled 1 to 6 then set it at 3. The best way is by sticking a thermometer in the refrigerator and it should be below 40F.

Get a refrigerator thermometer, about $3 - 4.00! You want the temp to be below 40 degrees! The thermometer actually let's you know if you need to turn it up or down!
Go with the first two answers, they are right on .
