Customer complained that the refrigerator side is forming ice or not defrosting. If the refrigerator is not defrosting, the defrost heater assembly might be burned out. When it happens, the frost will build up on the coils and eventually no air will be able to travel through the coils to provide cooling. The defrost heater can be checked for continuity. If it doesn't have continuity it should be replaced. A defective control board may cause the same troubles with defrosting. A few times a day the control board is supposed to turn off the cooling system and turn on the defrost heater to melt away any frost that may have accumulated on the freezer evaporator coils. Diagnostic found that was indeed the situation. After replacing the main control board, the issue with cooling was resolved.
