U Rail Curtain Troubleshooting

This guide listed some normal troubles while using the U rail curtain.

• My Curtain could not work smoothly. 

Curtain's motor is running but doesn't move. 

Curtain's power is weak or running slowly. 

Curtain gets stuck while running. 

Please kindly take a video of the Curtain issue and send feedback via the SwitchBot app so that we could solve it for you as soon as possible.

Caution：

We need to check the motor of the Curtain to identify the issue. Please take the Curtain off from the rail and use the app to control the Curtain so that we could see the Curtain wheel clearly. 

If the Curtain's power is weak, please use your finger to stop the wheel while it is running and take the video of it so that we could identify the issue. 

• One of my Curtain could not run as fast as the others do.
• One of the Curtains in the same Curtain group is slower than another one.

Please kindly take a video of the Curtain issue and send feedback via the SwitchBot app so that we could solve it for you as soon as possible.

If this issue happens in a Curtain group, please switch the two Curtains and see if this was caused by the motor issue.
