Temp too cold in refridgerator

Please help. My refrigerator is freezing everything, even when turned down to the lowest setting.

I’ve seen a couple posts regarding this same problem, but none specific to my model of refrigerator. I’m guessing I might need to replace the thermostat, but I’m obviously not an expert, so I’ll defer to those that are.

Can anyone provide me with more info on:

  1. If it is/isn’t likely to be the thermostat
  2. What the part number might be

Thanks,

Mike

The fridge gets its cold air from the freezer through a vent between the freezer and fridge.The fan in the freezer blows air through it. There is a flap you adjust with the fridge temp. control. Make sure it opens and closes when you adjust the fridge temp. control.

Does the freezer ever stop running when the freezer reaches the selected temp.
