What should I do if Curtain 4 makes abnormal noise or gets stuck during operation?

1. Please check whether the device can be pulled smoothly by hand. If there is obvious resistance, please try to replace the wheel set with a more suitable one.

①If your curtain track is a telescopic track or a spliced ​​track, please try to use a conical wheel set. Please make sure there are no excessive gaps in the splicing track.

②As shown in the picture, if your track has obvious inward bulges, please use a conical wheel set.

1. If there is still obvious abnormal noise after replacing the suitable wheel set, please remove the Curtain 4 main unit and let the device run idling to see if there is any abnormal noise. If you have questions, please contact us via SwitchBot App > Profile > Help & Feedback > Feedback.
