Greetings and Salutations.. we have encountered a Kitchen Aid refrigerator that continues to freeze the air passages in the separating wall between the freezer and the food section, resulting in lack of cooling in the food section. The problem appears to be caused by condensation though we can not nail down the source. The doors seals are good and the ice flap is sealing correctly. The frost pattern on the evaporator looks perfect. The freezer is performing nicely. We just find solid ice in all of the separating wall air ducts and inner chamber. Any ideas?
