What are the symptoms of a faulty car evaporator sensor?
1 Answers
When the evaporator temperature sensor is damaged or fails, it prevents the refrigeration system from maintaining proper temperature control. More information about the evaporator temperature sensor is as follows: 1. Introduction: The evaporator temperature sensor serves to protect the air conditioning system by preventing frost formation on the evaporator surface, which would reduce heat exchange efficiency. Typically, when the evaporator surface temperature reaches around 2-4°C, it is considered the frost formation temperature, and this feedback is sent to the AC switch to control its on/off operation. 2. Principle: The working principle of the evaporator temperature sensor is that after the air conditioning is turned on, the evaporator continuously cools. When the temperature reaches the set value, a signal is sent to stop the compressor. If the signal is continuously sent to the compressor, it will keep working. The compressor circuit is disconnected when the temperature meets the set requirements, stopping the compressor, and the circuit is reconnected when the temperature rises above a certain value.
