The freezer is frozen, ice getting frozen and the fan keep running. If I turn the thermostat down still the fan keep running.
You will want to check to make sure that the unit is not frosting up causing the unit to continuously operate. If it is then you will need to check the defrost heater and thermostat for continuity. If there is not continuity then replace the part. If they both have continuity then replace the timer. If the coils are clear then replace the thermostat.
