What Is an Evaporator Fan Motor and How Does It Operate?

The evaporator fan motor is a component of the overall refrigeration system that draws air through the evaporator coils to remove heat from the circulating air. Depending on the type, the evaporator fan motor is also responsible for spreading cooled air throughout the freezer and refrigerator compartments.

This airflow cycle is essential for the refrigerator to function properly. If the evaporator fan motor fails for whatever reason, the temperature inside the refrigerator will rise.

Evaporator Fan Motors for Refrigerators

If your refrigerator is continually running or failing to keep its temperature, the evaporator fan motor may malfunction. To cool the fridge, an evaporator fan motor, also known as a refrigerator fan motor, works in tandem with the compressor. The fan pushes air across the cooling coils and circulates it throughout the refrigerator as it turns.

The temperature in both the fridge and freezer compartments will rise if the evaporator fan or motor fails. To compensate, the refrigerator may run continuously, consuming significantly more electricity than usual, and it may still be unable to maintain the proper temperature.

Replacing a single component of your refrigerator is often less expensive than purchasing an altogether new appliance. We have replacement parts for a variety of refrigerators and other appliances.

What happens if the evaporator fan stops working?

Your freezer will begin to defrost if the evaporator fan motor fails. With your hand, open the freezer door and feel for chilled air. You should be able to tell right away if the freezer isn’t working. If the freezer is chilly, the evaporator fan motor is most likely working correctly.

5 Indicators of a Failing AC Fan Motor

• Even if the air conditioner is turned on, the fan will not turn on.
• Even when the air conditioner is turned off, the fan operates.
• The fan is turned on; however, it rotates slowly.
• The fan turns on and off.
• When the fan is turned on, the condenser unit makes a rattling or buzzing noise.

What are your options for the evaporator motor?

SPMs

According to HVAC experts, shaded-pole motors are utilized in around 65 percent of evaporator fan applications, and they dominate the market due to their simple manufacture and inexpensive initial cost (ORNL). SPMs, on the other hand, have an average operational efficiency of only 20%.

PSCMs

Permanent split capacitor motors (PSCMs) are more efficient than SPMs, averaging 40 to 50% efficiency while relatively inexpensive.

ECMs

While more expensive than SPMs and PSCMs, electronically commutated motors are gaining favor due to their operational efficiency of 50% to 60%. These motors are also more cost-effective than SPMs since they run cooler and have a longer operating life.
