Frustrating error on WhirlPool American Fridge/Freezer

We have a WhirlPool American Fridge/Freezer that are causing us serious issues.

It is one of the following models. But number have fallen off:
S20EFII23-A, S22DFSS30-A/G, S20BTSB21-A/G, S20EFII23-A, S22DFSS30-A/G, S20CCBB31-A, S20CCSS31-A/UK, S25CCSS31-A/UK, S20BTSB21-A/G

Issues started a long time ago with short random chattering sounds from front board and light blinking when using Icemaker.

First we replaced all back PCB capacitors
with a repair kit:

Then we replace the front board and introduce a new error. Display “blinks” CF after app. 3 minuts and nothing works:
front board kit

Then we replace the full back board:
back board kit

And still it doesn’t work.

Errors and things that works:
– Ice machine works (But turner arm does not mix the cube so they get stock together. It turns when getting ice).
– Freezer and frigde works. (But fridge periodically gets very cold in the top shelves)
– Constantly shows CF in display whit the new front board, but not chattering noise or blinking light.

Please help my wife is not happy 🙂
