Possible sounds.

Water that flows, caused by the refrigerant in the air conditioner. That is the sound made by the water in the air conditioner, heard when the water is pumped out from the air conditioner during cooling and drying operations. When the refrigerant flows into the air conditioner even when the air conditioner is not working and all the other rooms in the house are operating.

Blowing, a sound that occurs when the flow of the refrigerant in the air conditioner is switched over.

Pinging occurs when the size of the air conditioner increases or shrinks due to temperature changes.

The air conditioner does not work.

Check that:

Is it possible that the breaker is off or that the fuse was blown?

Is it possible that there is a power failure?

Are there batteries that are included in the remote controller?

Is the timer set already correct?

An abnormal functioning during an operation.

It is possible that the air conditioner will malfunction because of lightning or radio waves. Turn the breaker off again. Then try running the air conditioner with the remote controller.
