The electric curtain rod keeps ringing after closing.

If there is abnormal noise in the electric curtain track, there may be foreign objects in the track. In this case, the track should be cleaned. In addition, there is something wrong with the track pulley in Haikou.

The normal pulley is spinning. If there is abnormal noise, it is possible that the pulley does not rotate, resulting in abnormal noise. In this case, if there is no foreign body in Ren Huang, you can drop a few drops of oil on the pulley or drop a few drops of oil on the slideway, and basically there will be no abnormal noise.
