GE side by side Not cooling

I have a GF freeze which is not cooling on top section. I thought its a Evap fan, opened up a panel and found fan is running.
Upon a careful examination, Fan only runs when i unplugged and plugged on for some hours, then it goes off again.

Any suggestion? Do i need to replace the Evap fan or its some other issue.

Respectfully.

changing evap fan fixed my issue.
