Door Glass Seal

Hello Matt, thank you for your question. Im not sure what kind of material this is, but the seal part number W11126230 is the Door Glass Seal for the door on your model number Med7100dw1 . It seals around the opening to the inside of the window. I hope this helps!

Hello Paul, thank you for your question. The door seal would be the first part we would recommend changing to fix this issue. I hope this helps!
