Common Air-conditioner Error Codes

The error codes provided here are based on the best of my knowledge and the same set of error codes may be different depending on the model of the AC.

Disclaimer: I am not liable for any mistakes in these malfunction codes.

When the “timer” LED light blinks, it doesn’t mean that the timer is faulty. In most cases, the manufacturer uses these blinking LED lights to tell you that there is a fault within your air conditioning system.
