Why this happens

When a shutter won't go up, it's usually one of three things: no power or signal reaching the motor, a mechanical jam or locked part, or (on manual shutters) a spring that's lost tension so the shutter is too heavy to lift.

Likely causeTell-tale signs
Power off, tripped breaker or isolator offNothing happens at all
Lock seized or not fully releasedShutter won't lift at all from the bottom
Motor failed or overheatedHumming, clicking or silence when pressed
Snapped or weak spring (manual)Shutter suddenly far heavier than usual
Slat or bottom bar jammed in the guideShutter lifts slightly then stops

Safe checks you can do first

  1. Make sure all locks and padlocks are fully released, including side and bottom locks.
  2. Check the breaker and isolator switch; reset a tripped breaker once only.
  3. Try both the wall switch and remote.
  4. On motorised shutters, find the manual override (chain or crank) and try it gently.

What not to do

  • Don't use tools to lever the shutter up.
  • Don't let several people try to force a heavy manual shutter, as a broken spring can make it drop suddenly.
  • Don't keep resetting a breaker that trips again. That's an electrical fault.
💡 Fastest way to a fix: WhatsApp us a short video of the shutter (from a safe distance), a photo of the motor or lock area if visible, and your location. We'll usually be able to tell you the likely cause and a price range straight away.

How we fix it

We find whether the fault is power, controls, motor, lock or spring, then repair it. Often we get you open on the first visit, by replacing the lock, freeing the jam, re-tensioning springs or repairing the control box. If a motor must be ordered, we can usually open the shutter manually in the meantime.

How much will it cost?

Jam and lock repairs start from $150–$180. Spring work starts from $250, and motor replacement from $600. Urgent after-hours attendance starts from $250.

Note on pricing: these are starting prices. The final cost depends on the complexity of the fault, shutter size and type, parts needed and site access. A site visit is needed for an accurate quote, and the site visit is free. See the full price list.

Frequently asked questions

How do I open a motorised shutter with no power?

Most have a manual override, usually a chain hoist or crank handle near the motor. Use it gently. If it's very stiff, stop and contact us.
