The ice buildup is normal, especially if you are in an area of high humidity. These are not frost free as all home refrigerators are now. We are full time and when in the Rio Grande Valley in the winter we need to defrost about once a month or so. We are now in WY and because it is quite dry we have not defrosted all summer. There two switches at the top of the refrigerator door one of which is for humid areas. Check your manual for which switch and how to set it. As to the freezer compartment when slide is in; can the door be just a little open? If so put something inside that is long enough that the door won't quite close. That would allow some air circulation.
