If your vehicles has an air conditioner, then it has too an evaporator temperature sensor (switch). This switch has an important role in making sure the correct temperature is given, and that it doesn’t get too cold and then create frost on your evaporator core. This sensor is located on the evaporator housing or the evaporator itself. Its duty is to keep track of the temperature of the evaporator.
When this becomes faulty and is no longer working, the correct temperature readings wouldn’t be taken. This means that either too little or excess refrigerant can be sent into the evaporator, and give the wrong temperature. It’s a system that keeps the exact right temperature, so the temperature sensor is a very important component.
If there are some challenges about your air conditioner, here are some signs that the temperature sensor has gone bad and is need of replacement:
- When the air conditioning is running you may notice that the air flowing out of the vents is not maintaining a steady temperature. It may switch from being warm, or cold, and is not steady. This is a good sign that the evaporator temperature sensor has become faulty.
- If your air conditioning is on yet the air isn’t flowing through the evaporator, it could be because it has been frosted over. This is yet another indicator that the sensor is in need of replacement.
- Know that the evaporator temperature sensor doesn’t have a regular maintenance routine, so you have to be observant of the failure signs.
If you’re experiencing any of the above mentioned signs and you suspect your evaporator temperature sensor (switch) is in need of replacement please contact your auto technician.
