Depending on car type and brand as well as its equipment there are various fan types managed properly by a fan controller. The best known and commonly used car fans are, of course, those of the cooling and air-conditioning systems. The purpose of the controller is to supervise fan operation and to signal any damages and defects, thus its reduced performance. The reduced fan performance entails deterioration of driving comfort and endangers the work of vehicle engine. An example is the fan working in the cooling system. This fan is responsible for keeping appropriate temperature of all cooling system components. The fan should not allow the cooling system components to become overheated. These components cannot be also too cold and therefore the proper control of fan operation is of such importance. In the case of fan control malfunctions, the consequences may be disastrous, including car engine overheating and immobilizing. In one word, the engine may be even damaged.
Similarly, but maybe less dramatic is situation in the car air-conditioning and ventilation system. Faulty or malfunctioning fan in this system may be also quite troublesome, particularly in hot summers. Efficiently working controller is responsible also for proper operation of this fan. It is also responsible for the work of the entire system.
Only proven and original fan controller will be able to ensure proper operation of this component in your car. It should be also repaired and replaced in authorized service stations or approved garages.
