The massage chair freezes when turned on. There are limiters on the upper and lower ends of the back massage guide rail of the massage chair. This is to ensure the massage range of the massage wheel. Some massage chairs are limiters of the pressure switch room. After long-term operation, the quality of massage is not very good. The chair switch reed will be deformed, so that the signal cannot be transmitted in time, causing the massage wheel to hit the top and cause the crash, and even the motor will burn out. This can be done by rotating the lowering screw forcefully, moving the massager to the middle position, and then correcting the reed. You can also contact the manufacturer to provide a new control switch. If it is a light-sensing switch, you can wipe the dust clean.
