Frost Free Refrigerator all of a sudden is building frost in the freezer. Appliance is only 2 years old. Items in freezer are defrosting, but everything is still cold. What could be the problem?
If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.
check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.
