Why does my garage door open a few inches then stop?

The usual causes, safety checks, and 2026 repair costs.

If your garage door lifts a few inches and stops, you've almost certainly got a broken or worn torsion spring. The opener can't lift the door's full weight without the springs doing most of the work, so it strains, quits, or reverses. Stop cycling the opener and don't try to force the door up by hand. Spring replacement is a licensed-pro job because those springs store enough energy to break bones.

Stop if you notice this

  • Never try to loosen, adjust, or replace a torsion spring yourself. They hold enough stored energy to break fingers, wrists, or worse.
  • Don't stand or reach under a partially open door that stopped mid-travel. If a cable or spring lets go, it can drop fast.
  • Keep kids and pets out of the garage until the door is fixed or fully lowered and secured.
  • If the door is stuck partway up and you must leave, secure it with vice grips clamped on the track below a roller, then call a pro.
  • Extension spring doors should have safety cables running through them. If yours don't, mention it to the tech.
  • Winding bars, not screwdrivers, are the only correct tool for torsion springs. This alone is why it's a pro job.

  • Why it happens

    The torsion spring above the door does about 90% of the lifting work. When it snaps, the opener tries to lift the full door weight and stalls after a few inches. You'll often hear a loud bang (like a gunshot) hours or days before the door stops working.

    Call a pro when

    Any confirmed spring break. Call a pro. Torsion springs are under extreme tension and can cause serious injury.

First check: This one is not a DIY job, so bring in a licensed pro to handle the repair.

What's actually happening when the door stops short

Your opener is a small motor. On most homes it's rated 1/2 to 3/4 horsepower, and it was never designed to lift the door by itself.

The springs do the heavy lifting. A torsion spring above the door counterbalances almost the entire weight so the opener only has to nudge it along.

When that spring breaks, the balance is gone. The opener strains against 200-plus pounds, moves the door a few inches, hits its safety limit, and stops (or reverses).

That's why the symptom is so consistent. A few inches, a groan, then nothing. It's the single most common garage door failure we see.

If you heard a loud bang from the garage in the last day or two, that was almost certainly your spring letting go. Don't keep pressing the button.

The most likely culprits, in order

Start with the springs because that's where the money is. A broken torsion spring accounts for the vast majority of these calls.

Walk in and look at the shaft mounted above the door opening. A broken torsion spring shows a clean 1 to 2 inch gap where the tight coils separated.

If you have extension springs instead (long springs running along the horizontal tracks), look for one hanging loose or a cable dangling.

A spring doesn't have to snap to cause this. A fatigued spring that's lost tension over years leaves the door heavy and the opener struggling past the first foot.

Less often it's the opener itself, with the up-force set too low or a worn drive gear. And occasionally it's mechanical: a bent track, a roller out of its channel, or ice welding the bottom seal to the slab.

The hand-lift test sorts most of this out in thirty seconds, which is why it's step one of any real diagnosis.

What the pro will do

There is no do-it-yourself path we recommend for this repair. The safe and lasting fix comes from a licensed pro who can diagnose the true cause and complete the work correctly.

Booking a qualified tech protects your safety, your warranty, and your home. Call a licensed professional to handle it end to end.

What this costs to fix in 2026

Professional torsion spring replacement runs $150–$500 in most US markets. The spread depends on door weight, spring size, and whether you replace one or both.

Most of the bill is labor, the service call, and the fact that this work is genuinely dangerous.

Doing both springs at once is the smart money. The second spring usually adds only $40 to $80 because the tech is already there and set up.

High-cycle springs (rated 20,000 or 30,000 cycles) cost a bit more upfront but can outlast standard springs by years. If you use your door as your main entrance, ask about them.

Extension spring replacement tends to land at the lower end, often $120 to $250, since the springs are simpler and less tension is involved.

If the opener also got cooked from running against the dead spring, add $200 to $500 for a new opener. That's the expensive lesson from cycling the button too many times.

Action checklist

Can you wait, or is this urgent?

This one's genuinely high urgency, mostly because waiting tends to make it worse and more expensive.

Every time someone cycles the opener hoping it'll work this time, the motor grinds against a load it can't handle. That's how a spring job turns into a spring-plus-opener job.

A door stuck partway up is also a security and weather problem. It's an open invitation and, in bad weather, a way to flood or freeze the garage.

There's the practical side too. If your car lives in the garage and the door is jammed, you're stuck.

The safe move if you can't get a tech same day: get the door fully down, clamp vice grips on the track just below a roller so it can't be lifted, and leave it alone.

Don't leave a heavy door propped partway open on a broken spring. If whatever's holding it slips, it comes down hard.

Keeping the next spring from surprising you

Springs fail on a cycle count, so the best thing you can do is know roughly how old yours are.

If your springs are past 7 years and you open the door several times a day, start budgeting. They're near the end.

Twice a year, disconnect the opener and hand-lift the door. If it's getting heavier or won't hold at the halfway point, the spring is fading before it snaps.

A light spray of garage door lubricant on the springs (not WD-40, which is a solvent) reduces coil friction and can add life. A quick pass in spring and fall is plenty.

When one spring breaks, replace both and consider high-cycle springs. Paying once beats two service calls six months apart.

Listen for changes. A door that suddenly sounds louder or jerks on the way up is often warning you before the failure.

How we diagnose this in the field

When a tech pulls up to this call, the diagnosis usually takes under five minutes. The symptom is that specific.

First we look at the springs from the doorway. A visible coil gap ends the guessing immediately.

If the springs look intact, we release the opener and hand-lift the door to check balance. A door that won't hold at mid-height tells us the tension is gone even without a clean break.

We check the wire gauge, spring length, and inside diameter to spec the replacement, then confirm the door's weight if anything looks off.

We inspect the cables and drums while we're in there. A broken spring often means the cables took a beating too, and replacing both together is cheaper than a callback.

Last, we wind the new springs to the correct turn count, test the balance by hand, and reconnect the opener. A properly balanced door should float at waist height and move smoothly through its full travel.

Frequently asked questions

Can I still open the garage door if the spring is broken?

You can, but it's risky and hard. A double-car door weighs 200 to 350 pounds with no spring help. Get two people, lift from the bottom evenly, and prop it with sturdy supports. Honestly, it's safer to leave it down and use another exit until a pro comes.

Why did my spring break in cold weather?

Cold makes steel more brittle, and springs usually snap on the first opening of the morning when the metal is coldest and stiffest. The cold didn't cause the failure, it just picked the moment. The spring was already near the end of its cycle life.

How much does it cost to replace a garage door spring in 2026?

Expect $150–$500 for professional torsion spring replacement, depending on spring size, door weight, and whether you do one or both. Replacing both at once (which you should) is usually only $40 to $80 more than one and saves a second service call.

Should I replace one spring or both?

Both, if your door uses two. They wear at the same rate, so if one broke the other is close behind. Paying for a second visit in a few months costs more than doing them together now.

How long do garage door springs last?

Standard springs are rated around 10,000 cycles, which is about 7 to 10 years for a family that opens the door 3 to 5 times a day. High-cycle springs rated for 20,000 or more cost a bit extra but can double that lifespan. Worth it if you use the door heavily.

Is it the opener or the spring?

Quick test: pull the emergency release and lift the door by hand. If it's heavy or won't stay open, it's the spring. If it lifts easily and holds, the opener is the problem.

Can a bad spring damage my opener?

Yes. Running the opener against a broken spring forces the motor to lift the full door weight it was never sized for. Do it enough times and you can strip the drive gear or burn out the motor, turning a $300 spring job into a $600 spring plus opener job.
