similarly, Should radiator fan turn on when AC is on?
When the AC compressor is activated, it is actually expected that the radiator fan runs. For instance, the radiator fan is needed when the temperature sensor of the cooling fluid in the lower tank reaches approximately 212F.
on the other hand, Is it cheaper to run the fan on the AC?
Fans are cheaper to run than air conditioners, and can be used in place of air conditioners or along with them to save money. … You can actually raise the thermostat on your air conditioning unit by 4 degrees without lessening the cooling effect if you turn on the ceiling fan.

Once it reaches a 200 plus or minus depending on vehicle the fan will kick on.
Does the radiator fan affect the AC?
The radiator fan pulls air through the condenser, which removes the heat vapor of the refrigerant inside. If the radiator fan fails, it will affect the AC performance.
What tells the cooling fan to come on?
The engine temperature should trigger the fan to turn on. It will also turn the fan off once the engine has cooled to under 200 degrees. You may have heard of a part called the radiator fan switch or temperature fan switch. This is linked to a thermostat and works much like your home’s HVAC system.
Should I leave AC fan on all the time?

Should both fans be on when AC is on?
Both radiator fans should always run when the AC compressor is engaged. To check the temperature at which the fan comes on, turn the A/C off and keep the engine running until it reaches normal operating temperature. Most fans should come on when the coolant reaches about 200 to 230 degrees.
Which mode is best for AC?
AC professionals recommend only using the aircon dry mode for 1-2 hours, at most. While the “Dry Mode” does a good job in lowering air moisture, keep in mind that it shouldn’t be used to completely remove the humidity of the room. It should only be used to maintain humidity at a level that is ideal for human comfort.
Which AC mode is best for saving electricity?
According to the Bureau of Energy Efficiency (BEE), “By increasing your AC temperature by 1 degree, you can save about 6% electricity.” Setting your AC temperature to 24° C can help you save almost 25% on your electricity bill. In this mode, only the fan runs and the compressor is switched off.
What consumes more electricity fan or AC?

Should radiator fan run all time?
An electric fan SHOULD NOT run all the time. … Both radiator fans should always run when the coolant temperature sensor in the bottom tank of the radiator reaches about 212*F. It’s normal for some vehicles to have a fan run for a few minutes after the car is shut off, generally to keep the engine cool.
Is AC fan and radiator fan the same?
On some vehicles, for example, only the condenser fan operates with the air conditioner, while only the radiator fan operates based on engine temperature. On other vehicles, both fans can be activated by either air conditioning or engine temperature.
