During the operation of the self-test mode, the orange and green LEDs blink at the same time. To read the code, you need to count the number of blinks of the indicators. Thus, the orange indicator indicates the number of tens, and the green indicator indicates the number of units. First, orange blinks, after which there is a break for two seconds and green blinks. After that, another break for four seconds. Thus, the error indications of Karier air conditioners are repeated until the problem is corrected.
Example, if according to the instructions the error code of the air conditioner Carier 24:
- First, the orange indicator blinks 2 times;
- After that, the blinking stops for 2 seconds;
- Green indicator blinks 4 times;
- Break for four seconds.

As a rule, with slight mistakes, cassette air conditioners Carrier can cope on their own.
But if this does not happen, you should not try to open the device without the presence of a specialist who can accurately localize the error codes of Carrier air conditioners.
