Why is my Gree GWH12MB-D3DNA3D indoor unit emitting noise?

If you hear noise from the indoor unit of your Gree Air Conditioner, it may be due to the sound of the fan or compressor relay switching on or off. It can also occur when defrosting starts or stops, which is caused by the refrigerant flowing in the reverse direction.
