Chigo Air Conditioners Error Codes

Modern CHIGO air conditioners have a developed self-diagnosis system, according to the results of which the control system, upon detection of a malfunction, blocks the operation of the entire device and at the same time reports the cause of the malfunction.

 

The CHIGO air conditioning control system reports any malfunctions by flashing the LED on the panel of the indoor unit. If one or another malfunction of the air conditioner is detected, the LEDs light or flash in a certain sequence, which corresponds to the detected error. If the control system of the air conditioner has detected more than one error, then the fault with the highest priority is displayed first, and then all the others.

 

 

The codes of malfunctions (errors) of CHIGO air conditioners are given in the table:

    Indoor working perfect later display reads F1
    compressor not running not even harming
    What is the solution

    Light is blinking 4 times on indoor split unit. Its 90 ° outside with high humidity. Do I need freon recharge?
