What Is the Work of a Control Module in an AC

In a nutshell, the control module is the brain of your air conditioner. The unit has a computer that helps control and regulates climate control operations.

The module controls the expansion valves in your AC to maintain constant heating or cooling of the refrigerant when the compressor is running.

In addition, the control module also opens and closes independent circuits depending on the program you have set on your air conditioning unit.

The Symptoms of a Malfunctioning AC Control Module

Now that you know the function of the aircon control module, let us look at some of the symptoms that might indicate a malfunction with the system.

  • Inconsistent cooling: One symptom of a malfunctioning AC control module is uneven cooling. After setting your climate control setting, like the “Cool Mode,” you might notice that the thermostat does not reach the set temperature.
  • Irregular cycle duration: Your AC can reach the desired temperature but struggle to keep it constant. It leads to the unit overworking, and you have irregular or shorter cycles when cooling the house or office.
  • Unresponsive air conditioner: If the control module malfunctions, the AC unit might also become unresponsive. The system might not be receiving the signals from the thermostat.
  • Uneven air distribution: The airflow distribution can also have a problem if the control module in the aircon fails. You might notice that some areas around the house are warmer than others.

Likewise, it is common for the vents to stop working once in a while if you have a faulty control module.
