Thanks to this forum I thought I was able to solve the problem of the wall between the fridge and freeze being too hot. I cleaned the coils and noticed the condensor fan was not running so I replaced it. However, the new fan is not running either. I have been using a small fan to cool the back of the fridge and it is helping the freezer to stay at 0 degrees. Is the next step to replace the control board? If so, which control board - AP3773712?

Thank you.
