The evaporator fan motor is responsible for circulating cold air from the freezer to the fresh food side of the refrigerator. All the cooling necessary to cool your food is supplied by the freezer evaporator. The freezing air is blown upwards, in French-door or bottom-mount refrigerators. The airflow is constant in most cases.
The cold air is regulated to keep a steady temperature by the use of a damper and damper motor. The damper is opened and closed based on the refrigerator temperature - as detected by a thermistor or thermostat.
When these fans go bad the fresh food will warm but the food in the freezer will stay frozen. You may also hear strange noise, rumbling, coming from the bad fan bearing.
When this happens, call a professional who has the necessary experience to complete your repair quickly and professionally.
