The noise of running water in your CIAC Air Conditioner is due to back flow of liquid in the refrigerant circulation. Check the refrigerant circulation and address the back flow issue.
Why CIAC CG21A Air Conditioner unit does not operate?
If your CIAC Air Conditioner doesn't operate, several factors could be the cause. It could be due to a power failure, disconnected power supply, tripped breakers, a damaged fan motor (indoor or outdoor unit), a faulty compressor, faulty protective devices or fuses, loose connections, activation of a protection device, voltage outside the specified range, an active TIMER-ON function, or a damaged electronic control board. Check the power supply, replace any faulty protective devices or fuses, check all connections, and ensure the voltage is within the correct range. If necessary, reset the protection device or replace the electronic control board. If the fan motor or compressor are damaged, consider replacing them.
