Why does my Refrigerator fan run only with the condenser on?
When the evaporator fan runs only with the condenser, you save up a lot of power. When the fan runs without any break, it causes air to circulate properly. This will produce an even temperature throughout the refrigerator.
Should the evaporator fan run all the time in a refrigerator?
If you understood the refrigerator cycle earlier, you would know that a faulty evaporator fan will prevent cool air from circulating. The evaporator fan is not supposed to run all the time but until the refrigerator reaches a set temperature. However, it runs in combination with the condenser and compressor fan. This is one school of thought.
What is the function of the fan on a refrigerator?
The evaporator fan takes the air from the refrigerator. It blows the air into the evaporator coils. The refrigerant, present in the evaporator coils, in turn, gives off cold air to cool the items inside. The compressor converts the liquid refrigerant into gas and pumps it into the condenser coils.
What is a refrigerator condenser?
The condenser in a refrigerator is a motor, and like the one in your car it needs constant airflow to remain cool enough for the working parts to remain in working condition.
Does fridge fan go on and off?
The fan in your refrigerator's freezer compartment is located near the evaporator coil where it can draw air across the coil and force cold air throughout your appliance for cooling. This fan comes on during the cooling cycle and shuts off during non-cooling periods.
Does a fridge compressor run all the time?
For refrigerators and freezers to maintain the proper temperature, the compressor will run much of the time. Refrigerators and freezers have compressors that are designed to run 80% to 90% of the time.
Should the condenser fan run when the compressor is running?
Yes they should be on at the same time. There's controls that can be added so the compressor runs and the fan cycles on and off in cool weather but when it's hot they both run at the same time. Compressor shutting down with the fan on means the compressor is overheating.
When should the condenser fan come on?
The condenser fan (if it has a dedicated fan) or the radiator fan most always comes in (with AC on) when the compressor discharge pressure (or, alternatively, the liquid line one; look for where a sensor or a switch is located on the high pressure line) rises over an operative threshold.
Should refrigerator evaporator fan run constantly?
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 fridge motor run all the time?
No, a refrigerator definitely should not be running at 100% capacity for an extended period of time. Although you may notice your fridge running non-stop during normal daytime hours, anything over a 24 hour period where your compressor doesn't get a break is something that should be inspected.
Why does my condenser fan stop running?
Lack of maintenance: This is probably the most common reason that causes condenser fan motors to overheat and shut off. Proper and regular lubrication of the fan motor is necessary for the motor to run smoothly. Periodically making sure that there's no debris or dust in or around the fan motor is also a good idea.
What happens if condenser fan doesn't work?
If the condenser fan is running you will see the fan blade spinning at speed (typically at 1725 rpm) and you will feel air blowing out of the unit. at BURNED-OUT COMPRESSOR, if the condensing unit fan is not working the compressor itself may shut down or even be ruined by overpressure or over temperature.
Should condenser fan run when heat is on?
The fan on your unit should spin when you want air in your house and shouldn't spin when the temperature of your house matches the thermostat setting. Heat pumps take in hot air from the outside and cool it before blowing it into your home.
What controls the condenser cooling fan?
The condenser fan relay is the electronic relay that controls the power to the AC condenser cooling fan. When the relay is activated the AC condenser fan is switched on so that it can keep the AC condenser cool.

What does the condenser fan do in a refrigerator?
The condenser fan cools the compressor and condenser coils as they work. The fan should run when the compressor is running. If the condenser fan does not function properly, the refrigerator's temperature can rise and the compressor can overheat.
Significant Changes in Temperature Matter
The fan doesn’t need to be constantly running as long as there are no significant changes in temperature within the unit itself. If there is an increase in heat or humidity, it will turn on automatically without any input from us humans!
Bonus: Tips on Keeping It Running Smoothly
Make sure there is enough space inside the compartment so that hot air has some room to escape instead of staying trapped with all those cold items;
Conclusion
The answer to this question is not always as simple as it may seem. Many factors can determine whether or not a refrigerator’s fan will be running, but the most common reason a fridge runs its cooling fan without stopping is because of heat from food being stored in the freezer.
Why does my refrigerator fan run with no break?
When the evaporator fan runs only with the condenser, you save up a lot of power. When the fan runs without any break, it causes air to circulate properly. This will produce an even temperature throughout the refrigerator. This is what some experts believe.
Why shouldn't an evaporator fan run all the time?
Most people believe that the evaporator fan runs all the time. However, others think it shouldn’t because it will use a lot of power. A faulty evaporator fan does not cool the food and defrosts the one in the freezer. The inside is warmer than it should be.
How does a compressor work?
The compressor converts the liquid refrigerant into gas and pumps it into the condenser coils. Here, the fan cools the gaseous refrigerant, and the heat is pumped out of the refrigerator.
What is inside a refrigerator?
Inside the refrigerator are the evaporator coils. The evaporator fan takes the air from the refrigerator. It blows the air into the evaporator coils. The refrigerant, present in the evaporator coils, in turn, gives off cold air to cool the items inside. The compressor converts the liquid refrigerant into gas and pumps it into the condenser coils.
What happens if the evaporator fan fails?
When the evaporator fan fails, the stuff in your freezer will defrost. Open the freezer and check if you can feel cold air. If yes, then the problem may not be the evaporator fan.
Why is the evaporator fan important?
