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.
See also: Chigo Air Conditioner Service Manuals
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:

My Chigo a/c is on F5 and F7 errors, do I need to replace the electronic circuit to fix it, can you help me to locate a vendor

Chico air conditioner 7.5kW.
FF fault.
Refrigerant is fine-not short, no blockage.
4wayvalve is fine
Pcb is fine.
WHAT OTHER ISSUES CAN FF FAULT REFER TO.
100 chigos purchased and about half have ff fault come up

My Chigo mini split keeps frosting over. I have had a HVAC person come by and check for Freon leaks and recharge the unit. It currently was working fine but is now frosted over again. I have noticed the heat indicator light keeps blinking where the fan turns off and on blowing warm air. I assume this is from it being frosted over. Any ideas on why this is happening. It goes into defrost mode but seems not to work

I would like to know what does it mean when a cassette type r22 aircon flashes defrost continuesly model CCA-24H

I have a split unit. The indoor unit blinks once every 1-2 seconds. I have no error code on my remote. What could the problem be

My power indicator light on the internal unit flashes, what does this mean?

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?
