I have a similar Samsung (with a Kenmore name tag on it) we bought several years ago from the local Sears scratch and dent store. We thought it was a good buy and it has been a good fridge. We bought an extended warranty. The fan started making a noise when it was 12 to 14 months old. Technician came out, removed the shelves and guts so he could take the back panel off to get to the ice on the coils (see pic below). I think this may be the same thing you are experiencing on your RV fridge. I am not advocating fixing it yourself as described above - but I watched the guy do it and took pics so I could do it if it happens again. I thought the pic would be helpful to this thread.
