I will be happy to help you out. There is a design flaw on your machine. I worked with these tbx boxes for years.
I will walk you through step by step on how to "adjust" the air flow to the fridge from the freezer.
Let me know when you have a phillips head screw driver and a flat head.

After looking at the manual for your machine, we need to check what compressor you have first. If your compressor on the machine looks like a giant "D" battery, I would look to replace the fridge. If you have a converted fridge, from R12 to R134, then we need to check for a freon issue or a possible defrost issue.
The machine should have a blue sticker on the back that says R134.
If this is the case then there is not air adjustment on this machine. There are two style of this tbx18 machine. One has a completely flat rear freezer wall. This has not air adjustment. The other has an air divider that sticks out from the rear freezer wall. This type has a "special" adjustment you can make to fix the air flow issue.
Give the machine a look when you get a chance and let me know what you find.
We can go from there. Thanks Again for using JustAnswer.com!
