The evaporator temperature sensor is an element of the vehicle's electrical air conditioning system. The sensor is installed on the air conditioner, determines the air temperature behind the evaporator and serves to prevent freezing of the evaporator during long-term operation of the air conditioner. The signal from this sensor turns the air conditioning compressor on or off when necessary.
Signs of a faulty evaporator sensor.
- Freezing of hoses.
- Spontaneous switching off and switching on of the compressor.
- The air conditioner does not work, there is no cold air.
- Air conditioning adjustment does not work.
In this case, contact a car service to diagnose the problem. If it turns out that your temperature sensor on the air conditioner evaporator is not working, you just need to replace it. It is better to replace the sensor in a specialized car service, since when performing work on replacing the sensor, certain knowledge, skills and abilities are required, and a special tool is also required.
The main stages of work on replacing the evaporator sensor
- Diagnostics of the electrical system of the car.
- Installation of the sensor on a car may vary slightly depending on the model, but as a rule it is located in the area of the stove behind the instrument panel. It may be necessary to remove the protective parts of the instrument panel to gain access to the sensor.
- Work must be performed with the battery disconnected.
- Dismantling the sensor, having first disconnected the sensor power connector.
