CNWAGNER New Cooling Fan Control Relay Module Ford Mazda 1137328684

Function:

The principle of cooling fan control module mainly involves water temperature sensor, thermal switch, electronic fan and engine computer control.

Water temperature sensor and thermal switch. Cooling fan control modules work by controlling the operation of the fan through signals provided by a temperature switch or a water temperature sensor. The water temperature sensor is usually integrated into the electronic fan to detect the temperature of the coolant. When the water temperature reaches a certain temperature, the sensor sends a signal to the electronic fan control unit, which in turn controls the fan to run at different speeds. For example, thermal switches, which usually have two speeds, are mounted on the water tank to detect the water temperature and send a signal to the electronic fan control unit, which in turn controls the high and low speeds of the fan.
Electronic fan. The electronic fan is controlled by the engine computer, which sends a signal to a relay when the water temperature rises to a certain temperature, and the relay controls the starting and stopping of the fan. The high and low speeds of the electronic fan are usually controlled by a thermal switch, and turning on the air conditioner usually requires the electronic fan and compressor to work at the same time.
Engine Computer Control. The engine computer is the heart of the entire system, and it controls fan operation based on water temperature, vehicle speed, and other factors. For example, when the water temperature exceeds a set temperature, the electronic fan automatically kicks in to lower the water temperature. In some cases, such as when the vehicle is traveling at high speeds, the air pressure difference between the front and rear of the vehicle may be enough to maintain the water temperature within a certain range, at which point the fan may not need to operate.
Overall, a cooling fan control module is a complex system involving a variety of sensors, switches, and electronic control units that work together to maintain normal engine operating temperatures.
