A garage door that will not open usually comes down to one of eight causes, and the right first move depends on what you hear when you press the button. If nothing happens at all, check power to the opener and make sure the manual lock is not engaged. If the motor runs but the door does not move, the trolley is disengaged or the opener gear is stripped. If the door feels extremely heavy or you heard a loud bang, a spring has broken, and that calls for professional broken garage door spring repair, not a DIY attempt. Do not keep forcing a stuck door, and never try to fix springs, cables, or an off-track door yourself. Those are the repairs that cause serious injuries. Start with the safe checks below, and call a technician for anything under tension. (If the door is beyond saving, that is a conversation about replacement or custom garage doors, but only after the immediate problem is diagnosed.)
Key Takeaways
- What you hear tells you where to look: silence points to power or a lock, a running motor points to the trolley or gear, a loud bang points to a broken spring.
- The most common safe fixes are restoring power, disengaging a manual lock, and re-engaging the trolley after the emergency release was pulled.
- A door that feels very heavy or dropped fast almost always has a broken spring. Do not try to lift or repair it.
- Broken springs, snapped cables, and off-track doors are the three most dangerous stuck-door causes. All three are pro-only.
- In cold weather, the door can freeze to the concrete. Thaw it gently rather than forcing the opener.
- If your car is trapped inside and you cannot safely free the door, that is when it is worth calling for same-day service rather than forcing it.
1. The Opener Has No Power
If you press the button and absolutely nothing happens (no motor, no lights), the opener is not getting power. This is the simplest cause and worth ruling out before anything else.
Why Your Garage Door Opener Has No Power
- Confirm the opener is plugged in. Plugs vibrate loose more often than people expect.
- Test the outlet with a phone charger or lamp to see if it is live.
- Reset the GFCI outlet and check the breaker panel for a tripped breaker.
- If a storm just passed, unplug the opener for 30 seconds and plug it back in to reset it.
Call a pro if: the outlet is dead and resetting the breaker does not restore it, which is an electrical problem.
2. The Manual Lock Is Engaged
Many doors have a manual lock (a handle or a sliding bar that shoots a bolt into the track), and if it is engaged, the door physically cannot open, even though the opener strains. This catches people who rarely use the lock or just moved in.
How to Tell If Your Garage Door Is Manually Locked
- Look at the center or sides of the door for a turning handle or a horizontal lock bar.
- Check whether a bolt is extended into the track on one or both sides.
- Disengage the lock (turn the handle, slide the bar back) so the bolts retract.
- Try the door again.
Call a pro if: the lock is jammed or corroded and will not release.
3. The Trolley Is Disengaged (Emergency Release Was Pulled)
If the motor runs but the door does not move, the trolley has come disconnected from the opener carriage. Usually someone pulled the red emergency-release cord to open the door by hand and it was not re-engaged.
How to Re-Engage a Garage Door After the Emergency Release
- With the door fully closed, pull the red release cord toward the door to reset the lever.
- Run the opener once. The trolley should click back onto the carriage automatically.
- If it does not, move the door by hand until the trolley snaps back into the carriage.
Call a pro if: the trolley will not re-engage or the carriage is cracked or worn.
4. The Door Is Frozen to the Ground
In cold weather, the bottom weather seal can freeze to the concrete, and the opener reads the resistance as an obstruction and gives up. The door will not budge.
How to Free a Garage Door Frozen to the Floor
- Stop pressing the button. Repeated straining can strip the opener gear.
- Break the ice seal with a hair dryer or by carefully chipping the ice at the base.
- Once free, dry the seal and floor and apply a silicone-based lubricant to prevent it freezing again.
Call a pro if: the weather seal is torn or the opener stripped its gear from the strain.
5. A Torsion or Extension Spring Is Broken
If the door feels extremely heavy, will not lift, or the opener strains and stops a few inches up, a spring has broken. Springs counterbalance the full weight of the door, so when one snaps the opener cannot lift it. This is a common cause and a dangerous one to touch.
Signs of a Broken Garage Door Spring
- A loud bang from the garage, sometimes mistaken for a gunshot, when the spring snaps.
- A visible gap in the tightly-wound spring above the door.
- The opener hums or lifts the door a couple of inches then stops.
- The door is impossible to lift by hand, or crooked when you try.
Call a pro. Always. Do not attempt to unwind, adjust, or replace a spring. This repair has caused serious injuries and deaths. A technician has the tools and training to do it safely.
6. A Lift Cable Has Snapped or Frayed
The steel cables work with the springs to raise the door. If one snaps, the door can jam, hang crooked, or refuse to open. Like springs, cables are under high tension.
Signs of a Broken Garage Door Cable
- The door is crooked, with one side higher than the other.
- A cable is hanging loose, frayed, or wrapped incorrectly on the drum.
- The door binds or catches on one side as it moves.
Call a pro. Do not operate a door with a broken cable and do not try to replace it yourself. The tension can cause serious injury, and a crooked door can fall or jam worse.
7. The Door Has Come Off Track
A door that jumped its track will jam and stop, and it is unsafe to operate because it can fall. This often follows a car bump, a snapped cable, or badly worn rollers.
Why Your Garage Door Is Off Track and Stuck
- A roller has popped out of the track, so the door binds.
- A hard impact knocked a panel or the track out of alignment.
- Worn or seized rollers dragged the door out of position.
Call a pro. Do not force an off-track door open or closed. The panels are heavy and unstable, and forcing it can drop the door or bend it beyond repair.
8. The Opener Gear Is Stripped or the Logic Board Has Failed
If the opener hums or runs with the trolley engaged but the door does not move, the internal drive gear is likely stripped. If the opener is completely dead after you have confirmed power, the logic board may have failed. Both are common on older openers.
Signs Your Garage Door Opener Has Failed
- A grinding or whirring motor with no door movement points to a stripped nylon gear.
- No response at all despite confirmed power points to a failed logic board.
- An opener more than 15 years old that fails repeatedly is usually near end of life.
Call a pro if: you suspect a stripped gear or a failed board. If your car is trapped inside and you cannot free the door, this is when same-day emergency garage door repair is worth the call. And if a frayed or snapped lift cable is part of the problem, add garage door cable repair to the job, since a technician can tell you whether a gear-kit repair is worth it or whether a new opener is the smarter spend.

Bottom Line: Listen First, Then Choose Your Fix
The fastest way to figure out why your garage door is stuck is to listen when you press the button. Silence means power or a lock. A running motor means the trolley or the opener gear. A loud bang and a very heavy door mean a broken spring. The first four causes on this list are safe to check yourself in a few minutes. The last four (spring, cable, off-track, opener gear) are under tension or need diagnosis, and forcing them can turn a repair into an injury. When in doubt, stop and call a technician.

Frequently Asked Questions
My garage door is completely stuck and my car is trapped inside. What do I do right now?
First, do not keep hitting the button, because forcing a stuck door can make the damage worse. Look for the red emergency-release cord hanging from the opener rail and pull it to disconnect the door from the motor, then try to lift the door by hand. If it lifts, you can get your car out. If it will not budge or feels extremely heavy, a spring is likely broken, and that is the point to call for same-day service rather than force it.
Why won't my garage door open even though the opener is running?
This is one of our most common calls, and it almost always means the trolley is disconnected from the opener. Usually someone pulled the emergency-release cord and it was never re-engaged. Close the door, pull the cord toward the door to reset the lever, and run the opener once to reconnect. If the motor runs and grinds with no movement even after that, the drive gear is likely stripped.
My door won't open and it feels really heavy when I try to lift it. Is that a broken spring?
In our experience, yes, that is the classic sign. The springs carry the weight of the door, so when one breaks the door suddenly feels like dead weight, often 100 pounds or more. Please do not keep trying to force it up, and do not try to replace the spring yourself. It is under enormous tension and is one of the repairs that most often injures homeowners. This one needs a technician.
I heard a loud bang from the garage and now the door won't open. What happened?
That bang is a sound we know well: it is almost always a torsion spring snapping. The release of tension makes a sharp crack that people often mistake for something falling or even a gunshot. After it breaks, the door will not open normally because nothing is counterbalancing its weight. Leave it closed and call a pro to replace the spring safely.
Can I open my garage door manually if it's stuck?
Sometimes, and only if the cause is safe. If the opener lost power or the trolley is disengaged, pulling the emergency release and lifting by hand is fine. But if a spring or cable is broken, do not try to lift it manually. Without the spring, the door is extremely heavy and can slam down. Our rule of thumb: if it does not lift easily and smoothly, stop and call us. For manufacturer guidance on the emergency release, see Genie.
My garage door is stuck about halfway. Why?
A door that jams halfway usually has one of three causes: something binding in the track (a bent section, debris, or a seized roller), a cable that has slipped or snapped on one side, or the door starting to come off track. Because a partly off-track door can fall, we recommend not forcing it up or down. Have it looked at so a small track fix does not turn into a bent door. For door and track maintenance guidance, see Clopay.
It's freezing out and my door won't open. Is it broken?
Probably not broken, just frozen. The bottom weather seal commonly freezes to the concrete overnight, and the opener reads that as an obstruction and stops. Do not keep pressing the button, which can strip the opener gear. Thaw the seal gently with a hair dryer or carefully break the ice at the base, then dry it and add a silicone lubricant so it does not refreeze.
How much does it cost to fix a garage door that won't open?
It depends entirely on the cause, so we will not quote blind. As a general guide, a power reset or lock release is a minor call, a broken spring or cable is a mid-range repair, and an off-track door or opener replacement sits at the higher end. We always give a firm price before starting any work, so there are no surprises after the fact.
Should I repair the door or replace it if it keeps getting stuck?
Our field rule of thumb: if the door is under 15 years old and the failure is a single part (a spring, a roller, a cable), repair is almost always the better value. If it is older, jamming repeatedly, or the panels are damaged, replacement often costs less over time. Age and how often it is failing are the two biggest factors, and we will give you an honest read before you spend money on an old door.
Is it safe to keep using my garage door after I get it unstuck?
That depends on what caused it. If it was power, a lock, or a frozen seal, then yes, once resolved it is fine. But if a spring, cable, or track was involved, the door should be inspected before regular use, because a partial failure often precedes a full one. In our experience, the doors that strand a car inside usually gave a warning sign first, so it is worth addressing rather than ignoring.
