Why Your Garage Door Won't Stay Open

Read what the door is telling you

"Won't stay open" shows up a few different ways, and they all point to the same place:

• You lift the door halfway by hand, let go, and it slides back down instead of holding.
• The door opens fully on the opener, then drifts down an inch or two over the next few minutes.
• Mid-cycle, the opener strains, slows down, or reverses on its own before it reaches the top.
• The moment you pull the emergency release cord to disconnect the opener, the door feels heavy and wants to drop.

All four are the same root cause in the vast majority of calls we get: the torsion spring — or springs — mounted on the header wall above the door has lost enough tension that it can no longer counterbalance the door's weight.

What a torsion spring is actually doing

Opener motors aren't built to lift a garage door's full weight. A standard 8x7 steel door with insulation weighs somewhere around 130-180 lbs, and a 16x7 double runs heavier still. The opener only has to add or subtract a small amount of force on top of what the spring is already doing — the spring, wound tight above the door, does nearly all the lifting. When it's properly tensioned, a door should feel close to weightless in your hands.

Every torsion spring is rated for a fixed number of open-close cycles, typically around 10,000. It doesn't fail all at once as it approaches that number — it loses tension gradually, which is why the "creeping down" symptom usually starts subtle and gets worse over a few weeks, not overnight. GTA winters make it feel worse faster: cold contracts the steel and stiffens the lubricant on an already-weakening spring, so a door that was borderline in November can be noticeably bad by January.

Test it yourself, safely, in under a minute

1. Close the garage door fully.
2. Pull the red emergency release cord to disconnect the door from the opener trolley.
3. Lift the door by hand to roughly waist height and let go.

A properly balanced door stays exactly where you release it, or drifts down no more than an inch or two. A door with a weakened spring will fall — sometimes slowly, sometimes fast enough that you don't want your hand under it. If the door drops hard or fast during this test, stop there: that's a broken or badly worn spring, and it's a two-person or professional job from here, not a DIY spring adjustment. Reconnect the opener trolley before you walk away, and don't leave a heavy door hanging unsupported on a weak spring.

What weakened springs look like day to day

• The opener strains audibly on the way up, or the door reverses partway through the cycle even though nothing is blocking the sensors.
• The door doesn't fully seat at the bottom, or fully clear the header at the top, the way it used to.
• A visible gap in the spring coil — an outright break — usually comes with a loud bang and the door won't move at all afterward, opener or manual.
• Manual lifting feels noticeably heavier than it did a year or two ago, even before the door starts creeping.

Don't just turn up the opener's force setting

The common instinct is to compensate by increasing the opener's force or "down force" setting through the wall control or app. That masks the symptom instead of fixing it, and it costs you more in the long run. A motor working against dead spring weight strains its gears, drive belt or chain, and circuit board, and it can push the opener's auto-reverse safety feature out of proper calibration — which matters if the door ever needs to stop on an obstruction. Replacing a $280 torsion spring is a lot cheaper than replacing an opener that burned out doing a spring's job for months.

The less common second cause: track binding

Not every "won't stay open" call is a spring. If the track is misaligned, a roller is bent, or the track has been knocked slightly out of true, the door can bind at one specific spot and creep past it under its own weight rather than sliding smoothly.

What you notice	Likely cause	Typical repair
Door creeps down evenly, from any height	Torsion spring losing tension	Single spring $280, or both springs $320-$460
Door binds or grinds at one exact spot	Track misalignment or bent roller	Track repair/realignment $180-$350, roller $120-$220
Door has visibly jumped the track	Off-track	Off-track repair $180-$450
Loud bang, then door won't budge at all	Spring fully broken	Spring replacement $280 (single)

The manual release test tells the two apart. A spring problem shows up as even heaviness throughout the whole travel of the door. A track problem shows up as resistance or a catch at one repeatable point, usually where you can also see the track pulling away from the wall bracket or a roller sitting crooked in the channel.

What happens if you keep using it anyway

A door that won't hold position is more than an inconvenience:

• A spring under uneven remaining tension is more likely to snap fully and without warning — a full break is loud and can drop the door suddenly.
• The opener keeps absorbing load it wasn't designed to carry, which shortens the life of a $600-$1,200+ opener over a broken spring you could have replaced for $280.
• A door that won't stay up is a door you end up leaving half-open, which is a real entry-point security risk, not just a nuisance.
• Cables and brackets under uneven load wear faster too, turning a single-part fix into a multi-part repair if it sits long enough.

Royal Garage Doors recommendation

If the manual release test shows the door dropping or drifting, don't keep running it on the opener and don't adjust the force settings to compensate — book a spring inspection. In almost every case this ends up being a single or double torsion spring replacement, and every spring repair we do carries a 3-tier warranty. The service call itself is free with any repair.

Royal Garage Doors has handled this exact call thousands of times across Mississauga, Etobicoke, and the rest of the GTA over 15 years in business, and it's part of why we're sitting at a 5.0 rating from 500+ reviews. See current rates on our pricing page, or book a repair and we'll confirm on-site whether it's the spring, the track, or both before any work starts.

Frequently Asked Questions

Why does my garage door fall when I stop lifting it halfway?

Because the torsion spring above the door has lost enough tension to no longer offset the door's weight. A properly balanced door should stay wherever you release it; if it falls, the spring is worn or broken, not the opener.

Can I fix this by increasing the opener's force setting?

No. Turning up the force compensates for the symptom but strains the motor, gears, and drive belt or chain, and can throw off the opener's auto-reverse safety calibration. It's cheaper and safer to replace the spring, which starts at $280.

How do I know if it's a spring problem or a track problem?

Disconnect the opener with the emergency release cord and lift the door by hand. If it feels heavy and drops evenly at any height, that's a spring. If it binds or grinds at one specific spot, that's usually a track or roller issue.

Is it dangerous to keep using a garage door that won't stay open?

Yes. A spring under uneven tension is more likely to snap suddenly, and a door left half-open because it won't hold position is also a security risk. It's worth having it inspected before it fails completely.

How much does it cost to fix a garage door that won't stay open?

If it's a spring issue, a single torsion spring is $280 plus tax and both springs run $320-$460. If it's a track issue instead, realignment runs $180-$350. The service call is free with any repair.
