manual roller shutter not going down

Your manual roller shutter refusing to go down is the home’s way of saying “try again, mate.” Start by checking the obvious: is the bottom bar catching on anything, and are the side tracks free of pebbles or bent sections?

• Locks or straps engaged/tangled — release or untwist before winding.
• Obstruction in the guides — vacuum the tracks and use a light silicone spray (not grease).
• Slats misaligned or dented — lift slightly, reseat the curtain, replace damaged laths if needed.
• Winder/strap drum jammed — inspect the tape, spring drum and pulley for frays or knots.
• Overwound spring tension — back it off carefully; if unsure, call a technician.

If it still won’t budge, disconnect the winder and test the curtain by hand with a helper; if that moves freely, the mechanism’s your culprit. Safety note: springs bite — leave axle/torsion adjustments to a pro (ServiceCentral can help). Fix the cause and your shutter will go down faster than your patience did.
