▷▷ 2021 ▷ How long does an evaporator temperature sensor (switch) last?

6 julio, 2021

If you have air conditioning in your vehicle, which almost all modern vehicles have, then you have an evaporator temperature sensor (switch). This switch plays an important role in ensuring that the correct temperature is reached and that it does not get too cold and then frost forms on the evaporator core. This sensor can be found on the evaporator housing or on the evaporator itself. Its purpose is to keep track of the evaporator temperature.

Once this part breaks down and stops working, it will not take the correct temperature readings. This means that too little or too much refrigerant can be released into the evaporator and create the wrong temperature. It is a delicate balance to maintain that exact exact temperature, which is why the temperature sensor is quite an important component. Now keep in mind that this is not a job that you will be able to do on your own, because air conditioning systems must be disposed of in a professional manner.

If you are in doubt as to whether the evaporator temperature sensor (switch) has reached the end of its useful life or not, here are some signs that it needs to be replaced:

  • When you have the air conditioner running, you may find that the air flowing through the vents does not maintain a constant temperature. It may be hotter or colder and it just won’t be stable. This is a good indicator that the evaporator temperature sensor has failed.

  • If your air conditioner is on but air is not flowing through the evaporator, it could be because it is icy. This is another good indicator that the sensor needs to be replaced.

  • Note that the evaporator temperature sensor (switch) does not have a regular maintenance schedule, instead you just need to be on the lookout for signs of failure to look for.

The evaporator temperature sensor (switch) is an important component when it comes to your vehicle’s air conditioning system. This part must be in good working order so that it can maintain the proper and constant temperature. If this part stops working, you will find that the air conditioner will not be able to maintain a constant temperature and frost can accumulate on the evaporator. If you experience any of the symptoms listed above and suspect that the evaporator temperature sensor (switch) needs to be replaced, get a diagnosis or book an evaporator temperature sensor (switch) replacement service with a professional mechanic.
