The electric rolling shutter door is stuck and cannot go up

1. If the electric rolling door cannot be rolled up, it may be because the curtain sheet of the rolling door is stuck in the guide rail. Everyone needs to find the curtain that is stuck on the rolling shutter door and level off the curtain. If the curtain is stuck in the guide rail due to deformation, we can remove the deformed curtain and replace it with a new one. 2. If the electric door curtain cannot be rolled up, it may be believed that there are sundries in the guide rails and it is stuck. We can clean up the sundries in the guide rails.
3. The link belt of the rolling door is broken or the motor fails, etc., which will also cause the curtain of the rolling door to fail to roll up. If it is caused by these reasons, we can ask professional maintenance personnel to repair it.
4. It may also be because the limiter has run too far. For example, when the power is off, we manually open the rolling door, causing the limiter of the rolling door to run too far, and the rolling door can only go down but not up. You can adjust the limiter to the effective limit range.
