The hotel air conditioning controller sounded.

There is something wrong with the remote control signal receiver.

There is dripping sound when the air conditioner is automatically turned on and off, which may be due to problems with the air conditioner remote controller, remote control signal receiver or air conditioner main control board. The automatic on-off of the air conditioner is caused by the frequent reception of abnormal signals by the air conditioner. If you want to find out what the problem is, you can replace the air conditioner remote control, or take out the battery of the air conditioner remote control first to see if it will return to normal.

If all the above methods don't work, you can see if the circuit board of the remote control signal receiver of the indoor unit of the air conditioner is abnormal, such as black or there is a lot of dust on it, and you can clean it to see if it will return to normal.
