water dispener not working
 

The water would come up 3/4 of the way inside the door, it seems to be stopped up at the dispener spout itself. I disconneted the water line between the water pump and dispenser and water runs fine up to the door. with the line off I used my air compressor blow air through the water line up through the door with door closed and dispenser activated and it seems to blocked Ice maker works fine. Iam thinking maybe there is a valve in the door not opening Could it be the pc board in the door
