Is condenser fan necessary?
Therefore, the condenser and fan are critical components when it comes to removing heat from the AC system. When the condenser fan cannot do its job, the pressure isn’t removed and the gas continues on through the system when it should be liquefied.
Does cooling fan affect AC?
Does Cooling Fan Affect Ac? A faulty radiator cooling fan can lead to an issue with the car’s air conditioning (AC) due to the huge quantities of air created by the cooling fan compared to the condenser. This fan pushes heat out of the condenser, making it easier to remove it with ice cubes.
Can I drive my car if the fan is not working?
Yes, you can drive your car without a radiator fan, but you never should. Your vehicle’s cooling system is crucial to its performance, and every time your engine overheats, you cause damage.
