An Electric Fan Control Unit also referred to as EFCU or just control unit is unique to each make and model of vehicle. The unit consists of a microprocessor and microcontroller which has been programmed to turn on, speed up, slow down and turn off the fan based on the engine's temperature. The unit helps to keep the engine at a healthy temperature throughout the year which reduces overall wear and tear.
One of the ways you will know that there is a problem with the unit is that your car will overheat. You will also notice that despite the temperature rising beyond the center point, the fan does not turn on. While there could be a myriad of other reasons which include a bad fan, in some cases, it is a failing control unit. Thankfully, replacing the unit is easy in most vehicles but not always cheap. So, always buy a high-quality unit which is specially designed for your vehicle.
