Hello. You need a new cabinet thermistor and while you are at it replace the evaporator thermistor. (The evaporator is the cooling coil behind the back wall of your fresh food section) . These sense the temperature in your frig. Both of them are behind the back wall of your fresh food compartment. You will need a wire crimper and a heat gun or lighter to heat shrink the wire connectors that come with the new ones.

You probably have some food on the way. Unload the freezer and see if the door would close better. Looks like you have a warm air leak.
