After talking with Ms. Janice B. she explained to me, after I told her my problem that the door would not close properly, what to do. She asked does it seal when closed. I said yes. She explained that it was not the seal but the worn cam risers (hinges) that should be replaced. I made the purchase, watched the short video, and was able to install them in a very short time. Thank you, Ms.Janice.
