Evaporator Temperature Sensor (Switch) Replacement Service & Cost

What is the Evaporator Temperature Sensor (Switch) all about?

The air conditioning in your car operates by circulating refrigerant to remove heat and moisture from the air entering your passenger compartment and dissipating it into the outside air. The refrigerant that passes through the evaporator inside your car is metered by the expansion valve so the set amount of cooling can occur without the evaporator freezing up. As air passes through the evaporator core, the refrigerant in the evaporator absorbs the heat and carries it out of the car.

The evaporator temperature sensor is mounted on the evaporator or in the evaporator housing to monitor the evaporator temperature. It prevents the air conditioning refrigerant from becoming too cold and having frost form on the evaporator core. If the evaporator sensor fails or starts to read incorrectly, the expansion valve can introduce too much or too little refrigerant into the evaporator. This can cause insufficient cooling due to a lack of refrigerant flow or frost formation on the evaporator.

Keep in mind:

  • Air conditioning systems are filled with refrigerants that require professional recovery and disposal.

How it's done:

  • The evaporator temperature sensor is verified and needs to be replaced
  • The defective evaporator temperature sensor is removed from dash evaporator case
  • The new evaporator temperature sensor is installed and dash reinstalled
  • The a/c is recharged
  • The vehicle is road tested for proper operation and a/c operation checked

Our recommendation:

The evaporator temperature sensor only requires replacement when it fails. But if the evaporator is being replaced it is advisable to change the temperature sensor at the same time. If it is determined that the evaporator temperature switch or sensor is not working as it should, it will need to be replaced by one of our expert mechanics.

What common symptoms indicate you may need to replace the Evaporator Temperature Sensor (Switch)?

  • No flow through the evaporator when the air conditioning is turned on due to frost
  • Temperature of the air that flows through the vents when the A/C is on fluctuates

How important is this service?

Although air conditioning draws moisture out of the air to clear your windows in humid weather, it is more of a convenience feature than a safety feature. Have the air conditioning evaporator temperature switch replaced as it suits you.

Peter
22 years of experience
Before booking any services with your mechanic, I was highly doubting whether to or not. I decided to give it a shot with the inspection. The mechanic that worked with me, Peter, took all doubts away. He arrived even early to the appointment. He was very professional, and extremely helpful. The mechanic went above and beyond expectations. Had very great customer service skills, easy to talk to and explained things thoroughly about problems with the car that needed attention. He allowed me to stress a tad less about my problem, knowing he had it fully under control.

Awesome - first experience with Your Mechanic and first experience with Deuwn, and I wouldn't use anyone else. He had no problem working on my car even when I was away from home (left my car keys with apartment security guard and Deuwn took care of the details). He also had no problem calling a friend (whose phone number I had left for contact) with his after-inspection update when I was in an out-of-reach timezone. Good stuff all around - he realized during the repair that one of the parts didn't actually need repair, so he cut it out of the quote and I saved money. He even told me that I need new tires - which is a service that Your Mechanic doesn't provide.
