Fault
Possible cause / solution
... the roller shutters stop during downward travel?
a) The roller shutters may have hit an obstacle.
Move the roller shutters back up and remove the obstacle.
b) Slats have shifted out of alignment.
If possible, move the roller shutters back up and realign the slats.
c) The roller shutters scrape against the window frame inside the
roller shutter box due to the lack of a pinch roller or insulation
material may have come free and is jamming the roller shutters.
Open the roller shutter box and rectify the fault.
Lubricate any stiff areas with gliding wax if necessary.
d) The roller shutters are too light.
Increase the weight of the roller shutters by, for example, adding
a piece of flat steel to the bottom slat.
