Troubleshooting Guides
Try these basic checks before arranging a service call.
Motorised Roller Shutter
- Check the electrical board to ensure power is still on.
- If the door has two keyswitches, try operating it with the other keyswitch.
- Check whether the emergency mushroom-head button has been pushed in.
- Check whether the declutching cable has been disengaged. When safely accessible, disengaging the motor allows manual operation.
Folding Closure
- Check for dirt in the floor socket and press the cap gently to confirm it moves.
- Lock the floor lock down before engaging the top pin.
- Check that the floor and head-track holes align with the locking pins.
- If fitted, confirm the breakout door is completely closed.
