Roller shutter not working? Walk through the most common causes and step-by-step fixes before calling a technician. Covers electric and manual systems.

A roller shutter that stops mid-travel usually comes down to a power fault, an obstruction or a worn component.
Before you call a technician or start pulling panels apart, try these quick checks first. They fix many common faults that stop a roller shutter from closing.
This guide covers both electric and manual shutters. Work through it from top to bottom and you may fix the problem yourself; if not, you will have useful details to give the repairer.
Safety first: If your shutter is jammed in the open position and your home is unsecured, skip ahead to our emergency repair guide or contact Fix My Shutters for same-day service. A stuck-open shutter is a security risk you should address immediately.
Start with the obvious. It sounds basic, but some callouts end with the technician flipping a switch or replacing a battery.
If none of these fix it, the problem may be mechanical or electrical. Keep reading to narrow it down.
Electric roller shutters have several components that can fail, including the motor, capacitor and limit switches. The way your shutter behaves can help narrow down the cause.
Do not open the motor housing or touch fixed wiring. Switch the shutter off before a visual inspection. NSW Fair Trading requires an electrical licence for electrical wiring work, regardless of the job's cost.
| Symptom | Likely Cause | DIY Fix? |
|---|---|---|
| No response at all (remote or wall switch) | Power supply, blown fuse, control fault or failed motor | Check the external power controls. If power is available, call a technician |
| Hums but does not move | Failed capacitor or jammed curtain | No. The fault needs to be confirmed before parts are replaced |
| Moves one direction only | Control fault or limit setting problem | Check the user manual before changing any settings |
| Stops partway and reverses | Obstruction or limit setting problem | Clear visible obstructions, then test once |
| Moves slowly or struggles | Track friction, curtain misalignment or motor wear | Clean the tracks. If it still struggles, stop using it and call a technician |
A failed capacitor can leave the motor humming without enough starting torque to turn the shutter. A jammed curtain can cause a similar symptom, so the fault should be confirmed before any part is replaced.
The capacitor sits inside the motor assembly. Repair cost depends on the shutter, access and the part required, and it is not a safe DIY electrical repair.
If your shutter has a manual override, test it according to the manufacturer's instructions. Our guide to testing your roller shutter's manual override explains what to look for.
If the curtain moves normally with the manual override, the fault is more likely to be in the motor or controls than in the tracks. You may need to reset the roller shutter motor, but use the correct procedure for your model so you do not overwrite its limit settings.
If the wall switch works but a remote, timer or app does not, start with the control rather than the motor. Test one control at a time so you can isolate the fault.
Not every residential shutter has an external sensor. Check the manual for your make and model before trying to realign or re-pair any control.
Manual roller shutters rely on a strap, crank or spring mechanism. A working crank can also help when you need to open a roller shutter without electricity.
For spring issues, see how to adjust spring tension on manual roller shutters. For track problems, how to repair damaged roller shutter tracks covers the checks you can make without forcing the curtain.
A shutter stuck in a half-open position is easier to diagnose when it stops at the same point each time. Inspect both side tracks at that height.
Do not force a jammed shutter. Pulling hard on a stuck curtain can bend slats and strip gears. If gentle pressure does not free it, stop and use our full jammed shutter guide to identify the next safe check.
If your shutter moves but sounds rough, a part may be rubbing or have come loose. Stop if the noise is new or getting worse, as continued operation can damage the curtain or drive parts.
Run the shutter only if it is safe to do so and watch the curtain enter the pelmet. If it pulls to one side or bunches up, stop and arrange an alignment check.
Some faults are safe to troubleshoot yourself. Others need a qualified technician with the right parts and tools.
Call a professional if:
Our article on the risks of DIY roller shutter repairs explains which checks are safe to do yourself and which repairs should be left to a technician. If it involves the motor, spring or fixed wiring, a qualified roller shutter specialist is the safer option.
Opening housings or fitting unapproved parts may also affect the manufacturer's warranty. Check the warranty terms before doing more than cleaning, changing a remote battery or following the user manual.
Regular roller shutter cleaning and maintenance can help you spot built-up debris, worn parts or misalignment before the shutter jams. Use the service intervals and lubricant specified by the manufacturer, as requirements vary by model.
Keep the manual, service invoices and details of any parts fitted. That record makes future fault-finding easier and can help if you need to make a warranty claim.
Check the wall socket, the switchboard for a tripped breaker and the remote battery. If those checks are clear and neither the remote nor wall switch responds, stop there; the motor, controller or fixed wiring needs professional testing.
You can handle basic checks such as changing a remote battery and clearing loose debris from the tracks. Leave the motor housing, capacitor, springs and fixed wiring to a suitably qualified repairer.
Look for debris in the side tracks, a bent slat catching on a guide or a curtain that has moved out of alignment. If it stops at the same point after the tracks are cleaned, do not force it through the jam.
The cost depends on the fault, shutter size, access and parts required. A control or minor track repair is different from a motor replacement, so an inspection is the only reliable way to quote it; our guide to roller shutter repair costs in Australia explains the main price factors.
Yes. Heat can expand metal parts enough to make a tight guide bind, while wind, moisture and airborne grit can increase wear. Cleaning the guides and fixing damaged slats usually matters more than adding extra lubricant.
DIY work can affect a manufacturer's voluntary warranty, depending on its terms. Opening the motor housing, altering wiring or fitting unapproved parts may affect cover, although Australian consumer guarantees apply separately from voluntary warranties.
If you have worked through this guide and your shutter is still stuck, it needs an on-site inspection of the motor, curtain and tracks.
