1. Solution to partial dropping of water temperature sensor wiring: first observe whether the water temperature sensor wiring is falling off. If it is, check the wiring and weld it. It is better to ask professional personnel.
2. Solution to water temperature sensor failure: When the water temperature sensor is broken, the sensor can not correctly convey the water temperature. Just replace the water temperature sensor.
3. Solution to circuit board fault: The circuit board fault causes the water temperature sensor to have no power source, and many other problems may also occur. Generally speaking, the above two faults have not been solved, that is, the circuit board is faulty. Replace the circuit board.
