First let s see if the evaporator fan runs in the diagnostic test mode.
Kenmore elite refrigerator evaporator fan not working.
If this occurs the freezer may still get cold while the refrigerator will not get cold.
That is the most common thing on this unit.
If the unit and fan is iced over this means that either the defrost heater is not working the defrost timer is not working the control board is faulty etc.
If the evaporator fan is not working it will not circulate the cold air to the refrigerator compartment.
You re now in the test mode.
Etermine if the evaporator fan motor is defective try turning the fan blade by hand.
If the evap fan is not working the freezer will be cold near the evap unit but not elsewhere in the freezer.
If the fan blade does not turn freely replace the fan motor.
Appliance medic on this model the defrost thermostat can cause the fan not to come on as well.
