Hi,Welcome to Just Answer, My name is XXXXX XXXXX forward to helping you today.
Good morning, the problem is the solenoid in the dispenser itself, this is electronic and it is what opens the flap, these in most cases get rusted the corroded to the point where they do not allow the flap to shut tightly thus causing your Frost problem, this is a pretty simple repair, I am including a link below to the solenoid which also includes a video on how to replace it, this will take care of your issue. Thanks, Bryan
