Why Won't My Garage Door Open?
A garage door not opening is usually a broken spring or cable, an opener fault, or a release cord pulled during a blackout and never re-latched. Run the safe checks below, stop if anything looks damaged, and call us. Same-day across Perth, 24/7, no call-out fee.
Quick Answer
If your garage door won't open, the most likely cause is a broken spring or lifting cable: the opener strains or gives up, the door stays down, and by hand it feels far too heavy, often after a loud bang from the garage. After that come an opener fault, where the motor runs but nothing moves; a remote with a flat battery or wiped coding; a manual-release cord pulled during a power cut and never re-engaged; a roller jammed or a track bent; and no power at the socket. Check the power, the wall button, the release cord and the tracks before anything else, and do not lift the door if a spring or cable looks damaged. We fix all six causes across Perth, same day, 24/7, from more than one van carrying springs, cables and opener parts, with no call-out fee.
Common Causes
Broken spring or cable
The heaviest cause and the most common serious one behind a broken garage door. A spring snaps with a bang and the door becomes dead weight the opener cannot shift; a frayed or unwound cable drops one side and jams the door on an angle. Salt air on coastal doors and the original springs on 1990s and 2000s estate doors bring it on sooner. Keep everyone clear of the door and leave the fix to us.
Opener fault: motor runs, door stays put
A stripped drive gear, a worn trolley or a logic board that has tripped lets the motor hum or run while the door never moves. If the wall button gets the same result as the remote, the fault is in the head unit, and the motor-not-responding checks narrow down which part.
Remote or signal problem
A flat battery, standing too far away, or coding lost after a power surge all look like a dead door until you press the wall button and it works. Change the battery first. The full remote-not-working checklist covers range, lock mode and re-coding.
Manual release still engaged
Someone pulls the red cord during a blackout to get the car out, and the trolley never re-latches, so the garage door won't open after pulling the red cord even once the power is back: the motor runs up and down the rail while the door sits still. Our guide to opening a garage door by hand during a power cut shows how the release works and how it re-engages.
Door off its tracks or obstructed
A roller that has jumped the rail, a track bent by a car bumper, or sand, a stone or a broom handle wedged in the guide stops the door before it starts or a few centimetres up. Look, but do not pull. A jammed door is still under spring tension and can shift without warning.
No power to the opener
A tripped RCD, a lead knocked out of the socket by a stored bike, or a dead GPO. If the opener light is off and the wall button does nothing, start at the switchboard.
What You Can Check Safely
Safe to check yourself
- Look up at the opener: is its light on, and is the power lead pushed firmly into the socket? If not, check the RCD and circuit breaker at the switchboard, and try a lamp in the same GPO.
- Press the wall button. If it moves the door and the remote does not, the problem is the remote, not the door or the motor.
- With the door closed, look along both tracks for anything caught in them, a bent section, or a roller sitting outside the rail.
- Check the red manual-release cord. If it hangs lower than usual or the trolley sits away from the carriage on the rail, the release has been pulled and the opener is no longer connected to the door.
- Put a fresh battery in the remote and try again from a few metres away, not from the street.
Do not attempt
- Do not try to lift the door by hand if a spring has a gap in its coils or a cable is slack or frayed. A sectional door is far heavier than it looks, and without its spring nothing holds it up once it starts to drop.
- Do not keep pressing the remote or the wall button while the opener strains, hums or clicks. Every attempt heats the motor and chews further into the drive gear.
- Do not straighten a bent track, hammer a roller back into the rail or pull an object out of a track the door is bearing on. A door under tension moves without warning.
- Do not turn the opener's limit or force settings looking for more power. Raising the force defeats the safety reverse and can drive the door into whatever is jamming it.
When to Call a Technician
Call a technician straight away if any of the following apply:
- A visible gap in the spring above the door, or a cable hanging loose, frayed or wound off its drum.
- The opener hums, clicks or runs its motor while the door stays exactly where it is.
- On manual release the door is very heavy to lift, or it creeps back down when you let go.
- A roller is out of the track, or the track is bent, kinked or pulling away from the wall.
- The door still won't open after the checks above, or it opens one day and not the next.

A door that won't open leaves the car inside and, through the internal door, the house open. We are available 24/7 across Perth, same day, with no call-out fee. More than one van carries springs, cables and opener parts, so most doors are working again in one visit.
Frequently Asked Questions
Work from the cheap and safe end first. Confirm the opener has power, try the wall button as well as the remote, look along both tracks, and check whether the red release cord has been pulled. Those four checks clear up the remotes, blackouts and pulled cords that account for a good share of calls, and none of them puts you near a spring. If the door is still down, or if you can see a gap in a spring, a loose cable or a roller out of its track, stop there. Keep the car and the kids away from the door and ring us. Tell us what you found on the phone and we will usually bring the right part on the first trip.
Usually, yes, if the springs and cables are intact. Pulling the red release cord disconnects the opener so the door can be lifted by hand, and from outside most doors need a key release or the internal door to reach that cord first. If the door feels very heavy or will not stay up on its own, the spring has gone; put it down gently and leave it. The step-by-step method, including what to do with the door once it is up, is in the manual-opening guide linked from the release-cord cause above.
Either the opener is no longer attached to the door, or something inside it has let go. The first is the manual release: the trolley slides along the rail on its own while the door stays put, and re-latching it fixes the fault. The second is wear inside the head unit, most often a stripped plastic drive gear or a worn trolley or chain, which a motor straining against a heavy, spring-broken door tends to finish off. A grinding or freewheeling noise from the motor points to the gear; silence with a light that still works points to the board. Both are repairable in the driveway on most Merlin, B&D, Steel-Line, Jaytech and Superlift units, depending on the model.
It depends on which of the six causes it turns out to be. A pulled release cord or a tripped breaker is a small job; a new spring or cable pair, an opener gear kit or a replacement motor sit above that, and the door's size and type, how easy it is to get at, and whether you need us after hours move the figure as well. The quote is free and there is no call-out fee, so we look, tell you the cause, and give you the price before we touch anything. Everything here falls under our garage door repairs across Perth, same day where the van has the part.
It is when the car is trapped inside and you have to get to work, when the door is stuck part-way and the garage is open to the street, or when a spring or cable has broken and the door could drop. A remote with a flat battery is not. If it is urgent, say so when you ring: we are available 24/7 across Perth, and same-day service with no call-out fee applies at night and on weekends just as it does on a weekday morning.
