We have lived in our 3600RE for three months now with absolutely no problems with the refrigerator, except for a pinhole leak in the icemaker water line, which was outside the slide. I haven't looked, but I believe I read on this forum that there is already a fan back there. We are in central WI and I believe the highest temperature we have reached this summer was 92 deg. so I'm sure this has something to do with it, also.
