A garage door that won't open all the way usually has one of four problems: a broken torsion spring (the door feels heavy and stops within a few inches), an incorrect open travel limit on the opener, obstruction sensitivity triggering mid-travel, or a power or motor fault. Check the spring first — it's the most common and the only one that makes the door dangerous. Below are the checks in order, plus the safe way to open the door manually.
Free phone diagnosis: call 0434 099 873 and describe what the door is doing — how far it opens, any noises, whether it feels heavy by hand. We can usually identify the fault and quote before we arrive, anywhere on the Gold Coast.
Why Does My Garage Door Only Open a Few Inches?
Symptom: the door rises 5–10 cm and stops, and feels extremely heavy if you try to lift it by hand. Cause:a broken or badly worn torsion spring. The spring — not the opener motor — carries the door's 60–150 kg weight. When it breaks (often with a loud bang), the motor can't dead-lift the door and its overload protection stops it within the first few inches. With the door closed, look at the coiled spring above the opening: a visible gap in the coil confirms the break.
Technician-only. Springs are under extreme tension and injure people every year. Don't touch the spring, cables or winding cones, and don't keep pressing the remote — it strips the motor's drive gear. Spring replacement is fitted as a matched pair, usually same-day — call for a fast quote; we can usually price it over the phone. If you heard the break happen, read our guide: loud bang from the garage door and now it won't open.
Why Does the Door Stop at the Same Height Every Time?
Symptom: the door opens smoothly but always stops short of fully open, at the same point. Cause: the opener's open travel limit is set too low — the motor thinks that point is "fully open". This often appears after a power outage, a new motor installation, or someone bumping the adjustment screws. DIY fix: on most Merlin, B&D, ATA and Steel-Line motors, the travel limits are adjusted with screws on the unit or via a programming sequence in the manual. Make quarter-turn adjustments and test between each. If limits won't hold, the position encoder or logic board may be at fault — that's a motor repair job. If you'd rather we adjust and service it, call for a fast quote — we can usually price it over the phone.
Why Does the Door Stop or Reverse Partway Up?
Symptom: the door stops or reverses at different points, sometimes with shuddering. Cause: the opener's force (obstruction) sensitivity is tripping. That can be a genuinely sticky door — dry rollers, a seized hinge, debris in the tracks — or a force setting that's become too sensitive. DIY fix: watch the door move and look for binding points; clear the tracks and lubricate rollers and hinges with garage door lubricant (not general-purpose grease). If it still trips, leave the force adjustment to a technician — winding force up to mask a mechanical fault removes the safety protection that stops the door crushing an obstruction. A full service covers rollers, tracks, lubrication and force calibration — call for a fast quote; we can usually price it over the phone.
Why Won't the Garage Door Open After a Power Outage?
Symptom: nothing happens from the remote or the wall button, often after a Gold Coast storm. DIY checks, in order: test another appliance on the same garage circuit; check the switchboard for a tripped breaker and reset it fully off-then-on; confirm the motor's power lead is seated and its indicator light is on. Some openers lose their travel limits or remote pairing after an outage and need re-programming per the manual. If power is restored but the motor stays dead or only clicks, the logic board or motor has failed and needs repair or replacement — call for a fast quote; we can usually price it over the phone. Openers with battery backup avoid the stuck-in-the-storm problem entirely; worth considering when replacing an ageing motor.
How to Open a Garage Door Manually — Safely
- 1Door fully closed? Only use the manual release with the door fully down. Released while partially open, an unbalanced door can fall.
- 2Pull the red release cord hanging from the opener's rail straight down. You'll feel the trolley disconnect from the drive chain or belt.
- 3Lift slowly from the bottom. A healthy, balanced door feels light — the springs are doing the work — and stays put wherever you stop.
- If the door feels heavy, stop. A heavy door means the spring is broken — its full weight is in your hands and it can slam down. Lower it gently, step away and call us on 0434 099 873.
- 4Re-engage afterwards: pull the cord toward the motor (or run the opener once, per your manual) so the trolley clicks back onto the drive.

The Cost of Ignoring It
Running a door that won't open fully is the expensive option. Pressing the remote against a broken spring strips the opener's nylon drive gear — turning a straightforward spring job into spring plus motor work costing several times more. Forcing a binding door bends tracks and shears rollers. And a door that finally refuses to open with the car inside becomes an emergency call-out, where after-hours attendance adds a premium. A standard-hours diagnosis is the cheap path.

Call 0434 099 873Frequently Asked Questions
Why does my garage door only open a few inches then stop?
A door that rises a few inches then stops almost always has a broken or badly worn torsion spring. The spring carries the door's weight; without it the opener motor hits its overload limit within the first few centimetres. Check for a visible gap in the coiled spring above the closed door.
Why won't my garage door open after a power outage?
After an outage, first check the motor has power again — look for its indicator light and check the switchboard for a tripped breaker. Some openers also need their travel limits or remote codes re-established after power loss. If power is restored and the motor still won't respond, the logic board may have failed.
How do I open my garage door manually?
With the door fully closed, pull the red manual release cord hanging from the opener rail straight down. The door disconnects from the motor and can be lifted by hand. A healthy door feels light. If it feels very heavy, stop immediately — the spring is broken and the door is unsafe to lift.
Why does my garage door stop at the same point every time?
A door that stops at the exact same height each cycle usually has an incorrect open travel limit or an obstruction at that point — a bent track section, a damaged roller or a seized hinge. Watch the door as it moves: binding or shuddering at the stop point suggests a physical fault rather than settings.
Is it safe to keep using a garage door that only opens partially?
No. If the cause is a failing spring, every cycle strains the opener motor and can strip its drive gear, turning a straightforward spring replacement into a spring-plus-motor job costing several times more. If the cause is a track or roller fault, forcing the door bends the tracks further. Get it diagnosed first.
How much does it cost to fix a garage door that won't open fully on the Gold Coast?
It depends on the cause and your door: a travel limit adjustment costs far less than spring or motor work, and door type, spring size, parts and after-hours timing all affect the price. Call 0434 099 873, describe the symptom, and Fortex Door Services can usually give you a firm, free quote over the phone.
Can I adjust the travel limits on my garage door opener myself?
On many motors, yes — limits are set via adjustment screws or a programming sequence described in the manual for brands like Merlin, B&D and ATA. Make small changes and re-test the safety reverse afterwards. If limits won't hold or the door still stops short, the fault is usually mechanical, not settings.
