LG LFX31945ST (5), when ice is dispensed and stopped, the water dispenser automatically starts dispensing water. Opening door, stops the water from dispensing. Lock switch activation also stops water from dispensing. Ice maker works fine. Checked water dispenser switch, reads 25ohm activated, and open circuit when not activated. Unplugged refrigerator for 30 seconds and issue stopped. Is this indicative of a control board issue? If so any recommendations on how to find which one is the issue?
