Why Your Garage Door Won't Open, and How to Fix It

A garage door that will not open at all is most often a broken spring: when a torsion spring snaps, the door becomes far too heavy for the opener to lift, so the motor hums, strains, or moves the door an inch and gives up. The next most common causes are a power problem such as a tripped breaker, an unplugged opener, or a dead outlet, a remote or keypad that has lost its code or battery, an engaged lock or a pulled manual-release cord, and a door that has jumped its track or seized on a roller. This guide works through every cause in the order a technician checks them, shows you how to tell a spring failure from an electrical one in about a minute, and walks you through opening the door by hand tonight. A broken spring, the most common cause, runs about $250 to $500 to replace, and it is the one repair on this list you should not attempt yourself.

Start here: what is the door actually doing

Before you chase any single fix, watch the door for one cycle and answer two questions, because the answers split the whole problem in half. First, when you press the button, does the opener make any sound at all. Second, does the door move even slightly. A dead, silent opener points to power or the wall circuit. A motor that hums, grinds, or runs while the door sits still or moves an inch points to a mechanical problem, and on a door that will not open that mechanical problem is a broken spring far more often than anything else.

There are only six buckets a door that will not open falls into, in the rough order we see them: a broken spring, a power failure, a remote or keypad fault, an engaged lock or pulled release, an off-track or seized-roller bind, and a failed opener board or motor. The rest of this guide takes them in that order. Do the by-hand test in the next section first, because it tells you in one minute whether you are dealing with a heavy door or an electrical one.

The number-one cause: a broken spring

The springs above or beside your door, not the opener, do almost all the lifting. A torsion spring stores enough energy to counterbalance a door that weighs anywhere from about 130 to 350 pounds, so a half-horsepower or three-quarter-horsepower opener only has to nudge a balanced door. When a spring breaks, that counterbalance disappears, the full weight of the door lands on the opener, and the motor cannot lift it. That is why the most common signature of a no-open door is an opener that hums or strains, moves the door an inch or two, then reverses or stops.

Here is the one-minute test. Pull the red manual-release cord to disconnect the door from the opener, then try to lift the door by hand. A door with a healthy spring lifts with two fingers and stays put halfway. A door with a broken spring feels like dead weight and will not move, or slams back down. Also look at the spring itself: a broken torsion spring shows a two-inch gap in the coil, and a broken extension spring hangs loose along the track. If you see the gap or the door is dead weight, stop. A garage door spring is under extreme tension, and winding or replacing one without the right bars and technique is how people get seriously hurt. This is a repair for a technician, and it usually runs about $250 to $500 for a matched pair installed. We cover it on our spring repair page, and the warning signs in depth in our broken garage door spring symptoms guide.

When the opener is dead and silent

If the opener does nothing at all, no hum, no light, no click, the problem is almost always power rather than the door. Work through the cheap checks first, in this order.

1. Check the plug. Openers get bumped loose, and a storage-shelf project or a cleaning crew often unplugs the ceiling outlet. Confirm the cord is seated in the outlet.
2. Check the breaker. Find the garage circuit in your panel and look for a breaker that has tripped to the middle position. Flip it fully off, then on. A breaker that trips again right away points to a fault in the opener or outlet.
3. Test the outlet. Plug a phone charger or a lamp into the ceiling outlet. If it is dead, the outlet or a GFCI upstream is the problem, not the opener. Many garage outlets run off a GFCI that can be reset with a button on the outlet itself or on another outlet nearby.
4. Look at the wall button. If the opener is powered but the wall button does nothing while remotes still work, the button or its low-voltage wire may have failed. If nothing works from any control, the opener logic board may be dead, which runs about $150 to $350 to replace, or the unit may be at the end of its life.

Power problems are the fixes that cost nothing but a reset, so it is worth ruling them out before you call anyone. If the outlet is live, the breaker holds, and the opener is still silent, move on, because the fault is inside the opener.

When only the remote or keypad will not open it

If the wall button opens the door but the remote or the outside keypad does not, the door and the opener are fine and you have a remote problem. Check these in order.

The battery. A weak remote or keypad battery is the most common cause here, and cold weather makes it worse. Swap in a fresh coin cell or nine-volt and test.

The lock or vacation button. Most wall consoles have a lock button that disables the remotes on purpose. Press and hold it for a few seconds to toggle it off. A blinking light on the wall console often signals this lockout.

The code. A remote can lose its pairing after a power surge or a battery change. Reprogram it with the Learn button on the opener head. Our guide to programming a garage door opener covers every brand, and the full remote checklist lives in our remote not working guide.

Range and interference. If the remote works only up close, a corroded antenna wire on the opener or a nearby LED bulb throwing radio noise can cut the range. Make sure the antenna hangs down freely and try a different bulb.

When the door is locked or the release is pulled

Two simple things stop an opener as completely as any electrical fault, and both get missed. The first is a manual lock: many doors have a slide bolt or an L-handle lock on the inside that throws a bar into the track. If that lock is engaged, the opener strains against a bolted door and cannot move it, and forcing it bends the track or strips the opener gear. Check that no lock bar is thrown into the track on either side before you do anything else.

The second is the manual-release cord. If someone pulled the red cord to work the door by hand during a power outage, the opener trolley is disconnected, so the motor runs and the carriage moves but the door stays put. Re-engage it by pulling the cord back toward the door until the trolley clicks in, or by running the opener until the carriage relatches. If your door came off the opener during a storm outage, this is very often the whole problem.

When the door is off track or a roller has seized

A door that binds, catches, or opens crooked and then jams is a track or roller problem. A roller can rust and seize so it drags instead of rolling, a lift cable can slip off its drum and let one side hang low, or the track can bend where a car or a ladder clipped it. Any of these can wedge the door tight enough that the opener cannot lift it. Look for a door that sits at an angle, a cable hanging loose, a visible bend in the track, or a roller that has jumped out of the channel. Do not run the opener against a jammed door, because you will bend more track and can pull the opener off its mounts. Track and roller repairs run about $125 to $300, and we cover them on our track and roller repair page. If a cable has come off, our cable repair page covers that.

Why it will not open in cold weather

In freezing weather a door can refuse to open because the rubber bottom seal has frozen to the slab, or because thickened grease in the rollers and hinges adds enough drag that the opener reads it as an obstruction and stops. Free the seal from the ice, scrape the strip of slab under the door clear, and apply a lithium-based garage door lubricant to the rollers, hinges, and springs. Avoid using the opener to break a frozen seal loose, which can tear the seal or strip the opener gear. Cold also drains remote and keypad batteries fast, so if the wall button opens the door but the remote will not on a cold morning, start with a fresh battery.

How to open a garage door manually

When you need the door open now, whether the power is out or the opener has failed, you can disconnect it and lift it by hand. Do this carefully, because a door with a broken spring can drop hard once it is released.

1. Get the door fully closed first if you can. Releasing the trolley with the door partway up is dangerous, because if a spring is broken the door can slam to the floor. If the door is already open and you suspect a broken spring, leave it and call a technician.
2. Pull the red emergency-release cord straight down. The cord hangs from the opener rail and disconnects the door from the carriage.
3. Lift the door by hand. With a healthy spring the door rises smoothly. If it feels like dead weight, stop, because the spring is broken and lifting a full-weight door by hand risks injury.
4. Re-engage the opener when power returns. Pull the cord toward the door, or press the opener button, until the trolley clicks back onto the carriage.

Pulling the release is a temporary measure, not a repair. If you pulled it because the opener would not lift the door, the underlying cause, usually a broken spring, still needs fixing.

A quick symptom-to-cause table

What I see in Hampton Roads

On the coast the no-open call has a seasonal pattern the checklist above does not capture. In the summer heat, torsion springs that were already fatigued by salt-air corrosion snap when the metal expands, so July and August bring a run of dead-weight doors, and the spring is almost always the answer. After a named storm it flips: the July 4th storm surge this year sent us a wave of no-open calls that traced not to springs but to surge-damaged opener boards and to manual-release cords that homeowners pulled during the outage and never re-engaged. The salt air is the quiet thread through all of it, rusting spring coils and roller bearings faster here than inland. None of that changes the order you check things in, it just means Hampton Roads homeowners should suspect the spring first in a heat wave and the opener board or a disengaged trolley first after a storm. You can read the local versions in our Hampton Roads broken-spring guide and our emergency decision guide.

When to call a professional

Call a technician when the door is dead weight by hand or you see a gap in the spring coil, which means a broken spring, when the door hangs crooked or a cable is loose, which means a track or cable failure, or when the opener stays silent after you have confirmed power. As a rough national guide, a broken torsion spring runs about $250 to $500 replaced as a matched pair, an opener logic board runs about $150 to $350, a new opener installed runs about $400 to $700, and a track or roller repair runs about $125 to $300. We cover the mechanical side on our spring repair and track and roller repair pages, the electronics on our opener repair page, and the towns we serve on our Virginia Beach service area page. The mirror problem, a door that will not go down, is covered in our garage door won't close guide.

Frequently asked questions

Why won't my garage door open but the motor runs?

A motor that hums or runs while the door barely moves almost always means a broken torsion spring, because the opener is trying to lift a door that is now far too heavy for it. Pull the manual release and try to lift the door by hand: if it will not budge or feels like dead weight, the spring is broken and the fix is a professional repair, not more button pressing.

Can a garage door be too heavy to open because of a broken spring?

Yes. The springs, not the opener, do almost all the lifting, so when a spring breaks the full weight of the door, often 130 to 350 pounds, lands on the opener or on you. A half-horsepower opener cannot lift that, so it strains, hums, or moves the door an inch and stops. Do not try to force it up by hand.

How do I open my garage door manually when the power is out?

Pull the red emergency-release cord that hangs from the opener rail straight down to disconnect the door from the opener, then lift the door by hand. Only do this with the door fully closed, because if a spring is broken the door can slam down once it is released. When power returns, pull the cord toward the door and run the opener to re-engage the trolley.

Why won't my garage door open in cold weather?

In freezing weather the rubber bottom seal can freeze to the slab and stiffened grease in the rollers adds drag, so the opener reads the extra resistance as an obstruction and stops. Free the seal from the ice, clear the strip of slab under the door, and lubricate the rollers, hinges, and springs with a lithium-based garage door lubricant. Cold also weakens remote and keypad batteries, so swap those if the wall button works but the remote does not.

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

A broken torsion spring, the most common cause, runs about $250 to $500 replaced as a matched pair. An opener logic board runs about $150 to $350, a new opener installed runs about $400 to $700, and a track or roller repair runs about $125 to $300. Power and remote fixes are often free or the cost of a battery, so get a written quote before any parts work.
