Thank you charlieg and perryg114 for the links. My fridge seal is so-so and it may have to be changed sometime in the future. When I had an AS motorhome, I was told that to change the seals the doors had to be removed and new seals glued on, etc. etc. From what I see in these links, that may not be so, and the repair will be do-able. Thanks again.
