JStanley is correct with the information regarding the THERMISTOR.
Many problems appear after the unit has not been used and the fridge has been cleaned.
If the THERMISTOR has been dislodged from its holder, or has been moved, problems may appear.
Yes, it is a good idea to mark the location on the fin where the THERMISTOR is located, so that you have a reference if a problem arises.
In an earlier post it was mentioned that tapping the tubes on the rear will help. I would question that? and one would have to be very careful that damage is not done that most owners can not repair in their own shop.
As outlined in a previous post, if the roof temp. is close or equal to the side vent, then no air will move without a fan
. Fans are inexpensive and an easy backyard project for almost anyone. Internal fans are easy to install, and after they prove themselves, you can upgrade the power source at a later date. (see my post above

Make small adjustments and calibrated positions with a thermometer. It takes time and the outside temperature may influence the degree of cooling. That thermistor is meant to balance the freezer/food compartment temperatures. It’s not magic.
You can read this tip in the service manual, but if you don’t have one maybe you can find a manual on line. That thermistor often times get moved accidently when filling the refrigerator. If this works, I suggest you tape it down so is doesn’t move.
