Just replaced rusted solenoid. After drying area completely, and using the ice / water dispenser, I noticed more water [heavy moisture] collecting around the door and solenoid. The door appears tight around the edges. I know that without daily drying of this area,my solenoid will rust out again. How do I find out where this collection of water is coming from and stop it from collecting on this area? Also, is this normal? Thank you for your input
