GE side by side evaporator fan stop running

The evaporator fan stop running so the top of freezer and fresh food side are not cold. I replaced both the mother board and the evaporator fun motor but still the same. Anyone? Many thanks.

If you replaced both items at the same time, you may have wired up the new fan motor wrong.

I replaced the motor first. Since it was not helping then i decide to try the mother board. My ice maker has quit working for a while . The ice would melt then frozen, on and on. … i suspect the evaporator fan has not been working properly for a long time until recently it completely stopped running. What else could trigger this? Many Thanks.
