How often does the evaporator fan run?
The evaporator coils are usually located behind the freezer compartment, and the evaporator fan should be right in front of them, although it may be offset to one side or the other. The fan should come on whenever the compressor cycles on. If it doesn’t, the refrigerator won’t get cool enough to preserve your food.
Should freezer fan always be running?
The evaporator fan motor draws air over the evaporator coils and circulates it throughout the freezer. … To compensate for the decrease in cooling capacity, the freezer will run continuously in an attempt to keep the freezer cold.
Should fridge fan always be running?
The evaporator fan is responsible for circulating the cold air from your coils and into the refrigerator section. Without it working, the cool air will not be efficiently blown onto your fresh food. However, your refrigerator will still try to maintain that temperature by instead just running all the time.
What happens when refrigerator evaporator fan fails?
If the evaporator fan motor stops working, your freezer will begin to defrost. … Most freezers don’t run the evaporator fan motor when the door is open, so if the fan does work, it will turn off when you open the door. Check the temperature setting on the freezer to be sure it’s on cold.

The door or gasket creates an air-tight seal and if it’s damaged in some way it will leak air and the freezer’s compressor will then run continuously to compensate.
What does the evaporator fan motor do in a refrigerator?
As part of the refrigeration system, the evaporator fan motor draws air through the evaporator coils to remove the heat from the air. Depending on the model, the fan motor may also be responsible for circulating the cooled air through the freezer, and refrigerator compartments.
Why is my evaporator fan not working?
If the fan is not running, unplug the refrigerator and remove the evaporator fan cover. In many cases the problem is do to the fact that the evaporator fan cannot operate freely due to an ice buildup on the fan blades. … If the problem is bent fan blades, replace the fan blade.

Why won't my freezer shut off?
If your freezer won’t stop running and the temperature is not being maintained correctly, it could be due to a fault door or lid gasket. … A gasket with cracks or leaks will lead to frost buildup on the evaporator, which causes the compressor to run continually. Check the gasket for any signs of damage.
Does a freezer compressor run all the time?

Why is my refrigerator running but not cooling?
The most common reason why a refrigerator is not cooling is a problem with the evaporator coils. Over time, evaporator coils can become covered with ice, which prevents the coils from working properly. If the coils are covered in ice, the ice will need to be defrosted to fix the problem.
What happens when refrigerator condenser fan fails?
If your condenser fan stops, the temperature of the refrigerant will rise and the compressor may overheat. Eventually, the food may spoil. … The circulating air helps cool the compressor and the refrigerant in the condenser coils. The air also helps evaporate the water in the drain pan.
How long does it take a fridge to get cold?
While the exact times vary, refrigerators are generally able to get cold enough to store food in about two hours, and full cooling takes about eight hours. The best possible reason for the refrigerator not getting cold can be a lack of electricity.
Do all fridges have an evaporator fan?
Many older refrigerators and most small refrigerators (like small bar and dorm refrigerators) do not have fans, but most modern frost-free refrigerators have two. One is under the refrigerator to cool the compressor and force air through the exterior coils.
