No able to get information on your refrigerator since you're in Canada. 

On a situation like that, I would suspect the control board is the problem since it supplies power to the fan motor.  I suggest pulling the fan motor connection out and test the voltage coming out of the connector when the door is closed.  If you get power and then drops off after one minute, you have a control board issue.  If you continue to have power, then you have a fan motor issue.

Sorry I couldn't be of more help for you.

I would replace them both, LG has done some control board upgrades because of fan issues.
