So my freezer seems to be working pretty good, but the fridge (on bottom) isn't cold, I opened the bottom panel on the back and the fan wasn't spinning. I pushed it with my finger and it started and the fridge cooled off good, then it eventually stopped and the temp went up. I pushed it again with my finger and it started spinning.

Would replacing this fan fix the problem? Could it be something more major?

Thanks

Replace the motor. About a $40 fix
