Most air conditioner models Chigo equipped with the option of self-diagnosis of malfunctions. When a malfunction is detected, the air conditioner stops and the Chigo air conditioner error code is displayed immediately, which can be easily found in the instructions.
For error reporting, air conditioners use blinking diodes located on the front of the indoor unit. When a breakdown of the air conditioner is detected, the bulbs begin to blink or glow continuously, which is also reflected in the instructions.
