GE DFE28JMKGES - turbo cool will not work. French door fridge

[EverythingBreaks]

hello,

I have a GE DFE28JMKGES fridge that turbo cool will not work. Originally,The cold food section was not cooling, coils were frosted and fan wasn't running. I replaced the fan myself with an OEM part. The new fan seems to run occasionally, but doesn't seem to want to cool the fridge to set temp. and turbo cool function does not work. Coils are not frosted, compressor seems to be running with no issues. Freezer is working with no issues. Not sure which way to go next, control board or thermistors? Thank you in advance for any help or suggestions

Going to one of these tomorrow. Customer complaint is fresh food section not cooling. Did you solve your issue on this? If so what was your solution?
