I also am having cooling issues with my Dometic RM3862. Is it typical for these to operate better on AC than on LP? Like a previous poster, the freezer seems to be cold enough, but the refrigerator ...
I've never really noticed a difference between either heat source.
Now if freezer section is Cold (0-10*F) and food section is NOT getting cold enough (below 42*F) then you very well may have a plugged/blocked cooling unit. Only cure for that is replace cooling unit or new fridge.
