How do I know if my evaporator is bad?

Signs of Damaged Evaporator Coil Components

  1. Air coming from the vents is warm.
  2. Air conditioner starts and stops frequently but doesn’t properly cool your home.
  3. Air conditioner does not turn on.
  4. Refrigerant leak near the indoor cooling system components.
  5. Unusual noises from the cooling system, such as banging or hissing.

Where is the AC sensor located?

The thermostat sensor is located near the evaporator coils. These coils are inside your air conditioner unit. As the air is sucked through the return vents, the air passes by the sensor and the coils. As the air passes the sensor, it reads the temperature and compares that reading to the setting on your thermostat.

What does humidity sensor do?

The humidity sensor is a device that senses, measures, and reports the relative humidity (RH) of air or determines the amount of water vapor present in gas mixture (air) or pure gas. Humidity sensing is related to a water adsorption and desorption process [82].

What causes car AC evaporator to go bad?

WHAT CAUSES EVAPORATOR LEAKS? While most leaks are caused by damaged outer seams on the evaporator core, others are a result of corrosion inside the unit. This usually happens when leaves or other debris make their way in through the air intake and decompose.
