Hi , Our freezer has ice on wall little cold, ice maker not working and ref is no cold. Thanks
If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure defrost heater, defrost thermostat. http://www.acmehowto.com/howto/appliance/refrigerator/refrigerator.php
If they are ok it’s the defrost control. Part 13 on diagram 2.
