Why Does My Radiator Fan Keep Coming On. When the gauge or sensor is bad, the hitch. In order to keep the engine cool, the radiator fan comes on when it becomes too hot. There are several reasons why a car fan may keep turning on and off. The most common reason for a radiator fan to turn on and off constantly is a problem with the coolant sensor. Well, it could be a result of a problem with your temperature gauge or sensor. Since the relay operates as a switch for the fan’s power, a defective cooling fan relay won’t energize the circuit. The coolant temperature sensor is a thermistor and its resistance changes when the coolant temperature changes. Your car radiator fan still running when the car is off is likely due to a broken or faulty fan relay. A signal from the coolant temperature sensor is what triggers the ecu to turn on the radiator fan, and if it’s faulty, it can prevent the fan from working at all. The cause of the radiator fan running continuously may come from the temperature sensor, which is the part that determines when the radiator fan must operate. Occasionally, the fan turns on and off when it should be the other way around. One common cause is a faulty thermostat. The radiator fan turns on when the engine becomes too cold. So, why does the radiator fan turn on when the car starts? However, this operational mode can become erratic.
