The abnormal noise of the flying center control may be caused by the following reasons: 1. There is deviation or displacement of the plastic mold, and the vibration causes the sound of mutual friction, squeezing and loosening. Find the location of the noise to confirm the friction point, and put rubber things to block it. It has a good buffer effect. 2. The air outlet of the air conditioner makes abnormal noise. Check whether the air outlet of the air conditioner is loose, or whether it is a perfume bottle added to the air outlet
