A roller shutter that won't go up is usually caused by a power fault, motor issue, or blocked tracks.
You press the button or pull the strap and nothing happens. Or it moves a few centimetres and stops. Maybe it makes a humming sound but stays put. If that sounds familiar, you're dealing with one of the most common roller shutter faults in Australian homes.
The good news: most causes of a roller shutter that won't go up are identifiable without pulling anything apart. Some you can fix yourself in minutes. Others need a qualified technician, but at least you'll know what you're dealing with before you make the call.
It sounds obvious, but power problems account for a large share of "broken" roller shutters. Electric shutters draw from a dedicated circuit or a nearby power point, and if that supply is interrupted, the shutter simply won't respond.
Run through these checks before anything else:
Power outages can also reset the shutter's internal limit settings, which is a separate problem covered below. If power is fine and the shutter still won't move, keep reading.
Electric roller shutter motors have a built-in thermal fuse. If the motor gets too hot from repeated use or sustained operation, the fuse trips and shuts it down. This is a safety feature, not a fault. It stops the motor from burning itself out.
You'll notice this most often if you've been opening and closing the shutter multiple times in a short period, or if the shutter was running against resistance (dirty tracks, a warped slat) and the motor had to work harder than normal.
What to do: Stop using the shutter and wait 20 to 30 minutes. The thermal fuse resets on its own once the motor cools. If the shutter works again after waiting, the motor itself is fine. If it keeps tripping regularly, there's an underlying cause putting extra strain on the motor.
Roller shutters run along guide rails on both sides of the window or door opening. If anything gets lodged in those rails, the shutter can jam partway through its travel or refuse to move at all. This is one of the easiest problems to diagnose and often the simplest to fix.
Common things that block the tracks:
Inspect both guide rails from top to bottom. Use a torch if the area is shaded. Remove any visible debris by hand or with a soft brush. For grit and grime, wipe the rails with a damp cloth and then apply a silicone-based lubricant to reduce friction.
Automated roller shutters use limit switches to know where "fully open" and "fully closed" are. These are programmed positions. When the power cuts out unexpectedly, some motors lose those stored positions. The result: the shutter stops responding, or it moves a tiny amount and then halts because it thinks it's already reached its limit.
Resetting limit switches varies by motor brand. Some have a reset button on the motor head itself. Others need reprogramming through a wall switch sequence. Your installation manual will have the specific steps. If you don't have the manual, the Somfy and similar manufacturer websites often have downloadable copies.
Warning: Getting limit switch programming wrong can cause the shutter to slam into the ground or try to roll past the barrel. If you're not confident with the process, call a technician. A botched reset can damage the motor, slats, and guide rails all at once.
Not all roller shutters are electric. Manual shutters use a strap, crank winder, or spring mechanism to operate. When a manual shutter won't go up, the problem is almost always mechanical.
| Symptom | Likely Cause | Can You Fix It? |
|---|---|---|
| Strap pulls freely with no resistance | Broken strap coil or disconnected spring | No. Needs professional repair. |
| Winder handle spins but shutter stays put | Worn gear mechanism inside the winder box | No. The winder unit needs replacing. |
| Shutter lifts slightly then drops back | Weak or broken counterbalance spring | No. Springs are under tension and dangerous. |
| Strap is frayed or snapped | Wear and tear on the webbing | Sometimes. Replacement straps are available at hardware stores. |
| Shutter feels very heavy to lift | Spring tension has weakened over time | No. Spring retensioning requires specialist tools. |
Spring mechanisms deserve extra caution. They're wound under significant tension and can cause serious injury if released incorrectly. The Safe Work Australia guidelines on stored energy hazards apply here. Leave spring work to a qualified repairer.
That depends on where it's stuck and what it's protecting. A shutter jammed shut on a bedroom window is annoying but not an emergency. A shutter stuck open on a ground-floor shopfront or a window facing the street is a security risk.
Here's how to judge the urgency:
If your shutter is stuck in a position that compromises security, don't leave it overnight. Contact Fix My Shutters for a fast-response repair across the Sydney metro area, including Sydney CBD and surrounding suburbs.
When you call a roller shutter technician, here's what to expect. A standard diagnostic visit usually takes 30 to 60 minutes depending on the fault.
Many faults are fixed on the spot in a single visit. Motor replacements and spring retensioning may take longer if parts need to be ordered. Fix My Shutters carries common parts on the van, so most repairs across Sydney are completed the same day. With 15+ years of experience, we've seen every type of shutter fault going.
A roller shutter that won't go up is frustrating, but it's rarely a mystery. Start with the power supply. Check for obstructions. Wait out a thermal trip if the motor ran hot. For anything mechanical or electrical beyond basic checks, a professional repair is the safest path.
Don't force a stuck shutter. Pulling harder on a jammed strap or repeatedly hitting the button on an overheated motor turns a simple fix into an expensive replacement.
Contact Fix My Shutters for a fast, no-obligation assessment. We repair all brands of roller shutters across Sydney and can usually get to you the same day.
