What are the reasons why the first two fans of Ruifeng didn't turn around?

Relay failure, temperature control switch failure, water temperature failure and other reasons will cause the first two fans of Ruifeng not to turn. Relay: If the water temperature meets the requirements and the automobile radiator fan still can't work, then it is the relay of the fan. If the relay fails, the car radiator fan will not work. Temperature control fault: check the temperature control switch. Sometimes there will be some faults in this place, which will also have a certain impact on the operation of the radiator fan of the car, so you should also pay attention to the inspection. Water temperature is not up to standard: only when the water temperature in the car reaches the required temperature will the fan start to rotate normally. If the temperature is too low, the radiator fan will not rotate. Therefore, when the fan of automobile radiator does not rotate, it is necessary to check whether the water temperature meets the requirements first. Solution: Replace the damaged relay and the damaged temperature control switch to see if the water temperature meets the requirements. If the water temperature doesn't rise all the time, you need to check the car engine.
