Leaf sign is a healthy air conditioning mode. This sign is on the remote control. If you press this sign on the remote control, it will disappear. Of course, you said that the internal unit does not turn, which is not normal, because there will be no sign flashing when the internal unit does not turn. This flicker should be caused by fan failure in the internal unit, which may be caused by loose fan connection, abnormal fan capacitance and motherboard failure. Is it a capacitor fault? You can use a wooden stick to help the fan rotate at the moment when it is turned on, and move it away quickly, otherwise it will damage the fan. If possible, the internal capacitor is faulty, or the motor connection or motherboard is faulty. In this case, it is recommended that you directly call the official customer service for maintenance. I wish you a happy life.
