Air conditioning units have become a vital part of our daily lives, especially during the hot summer months aircon error code. They help to maintain a comfortable temperature inside the home or office and provide relief from the scorching heat. However, like any other mechanical system, air conditioning units can also malfunction and generate error codes. In this article, we will discuss what aircon error codes are, how to identify them, and how to fix them.
What is an aircon error code?
Air conditioning units have a built-in system to detect errors in their functioning. Whenever a problem arises, the system generates an error code, which is displayed on the unit’s digital display or through flashing lights. The error code indicates the type of problem that the system is facing and helps the technician to diagnose and fix it.
Different aircon brands and models have different error codes, and it is essential to refer to the manufacturer’s manual for a detailed list of codes and their meanings. However, some of the most common error codes are:
- E1 – This error code indicates a problem with the temperature sensor. The sensor may be faulty, or it may be disconnected. Check the sensor and its connections, and replace it if necessary.
- E2 – This error code indicates a problem with the indoor unit’s evaporator sensor. The sensor may be faulty or disconnected. Check the sensor and its connections, and replace it if necessary.
- E3 – This error code indicates a problem with the outdoor unit’s condenser sensor. The sensor may be faulty or disconnected. Check the sensor and its connections, and replace it if necessary.
- E4 – This error code indicates a problem with the aircon’s airflow. The system may have a clogged air filter or a faulty fan motor. Clean or replace the air filter and check the fan motor’s condition.
- E5 – This error code indicates a problem with the aircon’s power supply. The voltage may be too low, or there may be an electrical short circuit. Check the power and electrical connections.
- E6 – This error code indicates a problem with the communication between the outdoor and indoor units. There may be a faulty communication cable or a problem with the PCB board. Check the communication cable and replace it if necessary. If the problem occurs, replace the PCB board.
How to fix aircon error codes?
To fix an aircon error code, you need to first identify the error code being displayed by the aircon unit. Different error codes indicate different problems with the unit, and the solution to fix the error will depend on the specific error code.
Once you have identified the error code, you can refer to the user manual or contact the manufacturer’s customer service for guidance on how to fix the error. In some cases, you may need to call a professional technician to diagnose and repair the problem.

- Wait for a few minutes and then plug the unit back in and turn it on.
- Check the unit for any obvious signs of damage, such as a damaged power cord or a clogged air filter.
- If the error code persists, refer to the user manual for guidance on how to troubleshoot the specific error code.
- If you are unable to resolve the problem on your own, contact a professional technician to diagnose and repair the unit.
