Cafe fridge defrost issues
Freezer keeps frosting up.
I have a cwe19sp4nnw2 CAFE counter depth french door fridge over freezer w/o exterior water or ice maker. I can't find any service manual or mini manual for this fridge maybe because it is counterdepth? I also can't figure out if there is a diagnostic mode or how to access it. Most GE fridges use the external ice maker controls to enter diagnostic mode but I do not have that on mine.
The fridge started making a lot of noise and it turned out that the evaporator fan was rubbing on some ice that was built up on the condenser. I defrosted it but a few weeks later the same thing happened again. I again defrosted it and tested the defrost heater, and it looks good (non open, I forget the exact resistance but it was less than 100ohms I believe).
A couple weeks later I noticed some stuff on the top shelf of the fridge was frozen, then a week after that the fridge was room temperature but the freezer was still cold. I opened it up again expecting the damper to be the issue but the damper was open, no air was coming out of the vent from the freezer. So I again open up the freezer back panel to find that the evaporator is frozen solid. I defrosted it again to buy me some time to figure out what the real problem is. I know there is a defrost thermostat and maybe a defrost switch or timer but I am unsure where all of these components are and how to test these to know if they are bad.
If anyone has a manual with wiring diagrams and diagnostic mode info I would really appreciate it. Or if anyone has any pointers as to next steps, I could use all the help I can get!

The defrost thermostat WR50X10069 would need to be tested for continuity and is located at the top of the evaporator coil near the lines that go into the liner. If it does not have continuity when the evaporator is frozen up, the defrost thermostat would need to be replaced.

Thank you, I will check this. I heard that the thermostat might only be for runaway conditions on this model and I should check the temperature sensor. I will check both next time I open it up.
