If the barrier is moving very slowly, not lifting at all, or getting jammed frequently, the motor tube may be the source of the problem. Slow movement usually indicates that the motor tube is wearing out, while a barrier that does not lift at all may point to complete motor tube failure. Frequent jamming can suggest debris or physical damage inside the tube.
The LED behavior can also help identify the issue. If the LED blinks twice in sequence, this usually means that the accelerometer cable inside the tube has become disconnected. If the LED remains constantly green, this indicates a hardware issue, which could be related either to the motor tube itself or to the cover.
To inspect the motor tube, first disassemble it by following the provided disassembly video. Once the tube is open, check whether the white connector inside has become disconnected. If so, reconnect it carefully, using tweezers or a similar tool if necessary. You should also inspect the inside of the tube for any visible physical damage or debris that could be blocking normal operation.
If the motor tube is damaged beyond repair, it will need to be replaced. In that case, follow the provided installation video on the link below:
