LG fridge not cooling

LG fridge not cooling I purchased this fridge through Amazon in December of 2014. After 3 months the evaporator coil in the fridge froze up and the unit would no longer cool due to obstructed airflow. A service tech came out to thaw and chip out the ice in the coils a few times under warranty. Eventually they replaced the motherboard due to a known issue with the defrost cycle timing. This appeared to solve the coil freezing issue.
