11 Reasons Why Your Automatic Garage Door Won't Open (or Shut)
- The photo eye is blocked.
- Its power source is disrupted.
- The torsion springs are broken.
- Remote control malfunction.
- Snapped or loose cables.
- Sensitivity needs adjustment.
- The limit setting is off.
- The door has dislodged from its track.
- Something is blocking the door.
- "Disconnect" has been switched.
- The door is locked.
Garage Door Opener Repair
Read on for information, video tutorials, and troubleshooting tips for these issues. You'll also find tips for opening the door manually while you're trying to figure out how to fix the problem!
1. Your Photo Eye Is Blocked
Most garage doors from the past 15–20 years have a photo eye that detects if a person or object is blocking the door from lowering all the way. The photo eye will be about 4–6 inches off the ground for most doors, with an eye about the size of a pea. It shoots a laser across the length of the garage that, if interrupted, will cut off the signal used to lower and raise the door.
Check to see if the cord attached to the eye is cut or damaged; occasionally, a rainstorm or leak can damage the photo eye.
Dirt and dust can clog the eye and block the laser beam, so a thorough cleaning with tissue can sometimes solve this issue.
2. Your Operator's Power Source Is Disrupted
Sometimes, people unplug their power source and then wonder why their garage door opener fails to work. Sounds ridiculous, I know, but it does happen. Make sure that your garage door opener is plugged into a working outlet. Outlets sometimes go out without warning, so you can check to see if the outlet is working by plugging another working electronic device into it. Also, check your circuit breaker, fuse, or GFCI.
3. Your Garage Door Torsion Springs Are Broken
SNAP . . . bang . . . boom. That is the sound of a garage door torsion spring breaking. It can be a very loud noise that sounds like a firecracker or gunshot. Springs are rated for a certain number of cycles and are the first thing that will break in your garage door assembly.
Broken springs are the #1 source of customer calls for garage door repair companies. If you have a broken spring, you should NEVER try to open the door, as it can be hazardous. This repair should be left to a professional or someone with the right tools and skills.
4. Your Cables Have Snapped or Popped Off
Just like on a bike sprocket, your cables can sometimes become disengaged. Often, when a torsion spring breaks, the garage door cable will snap as a result. Sometimes, the cable will cause damage to a vehicle or wall, and if a person happens to be in the way of the cable, it can cause serious harm. If your cables have snapped, you should call a professional to help you. See the video above.
5. Your Sensitivity Is Out of Adjustment
This can happen to a newly installed garage door or an older one: if the sensitivity is set too low or high, the door will not open. Read the manufacturer's directions to reset the sensitivity. You can adjust the close force and limit switch to the correct levels, and you should be good to go!

6. Your Remote Control Is Malfunctioning
When your garage door doesn't open with the remote, a few things can cause this problem:
- You might be out of range.
- The antenna on the motor could be damaged or blocked from the signal; make sure it is hanging down from the motor.
- If the door opens with the wall switch, a simple battery change in the remote should do the trick.
- If all these fail, try reprogramming the remote.
7. The Limit Setting Needs Adjustment
If the door closes but then immediately pops open again, you'll need to check the limit settings, which help the mechanism determine how far to move the door to close it properly.
If the settings are off, the door will hit the ground before the opener believes it should. It will assume that it has hit an obstacle and will automatically backtrack to avoid damage. Check the owner's manual or the buttons on the motor to adjust the limit settings. It may take some trial and error to get the setting just right.
- Get a ladder and find the limit switch adjustment knob. Some models are labeled "up" and "down." Consult your owner's manual for help.
- If your door isn't closing, adjust it down. If it doesn't go up, adjust it up. A full turn of the screw equals about two inches of door movement on most models.
- It's smart to make minimal adjustments so you don't overdo it and end up slamming the door open or shut. Keep testing it to see if it works.
8. The Door Is off the Track
Of course, if the door is off track, it won't slide properly.
- Make sure the door is rolling smoothly along its metal track.
- Check the track for bends, bumps, gaps, or obstacles.
- Listen to and watch the door's progress: Do you hear any squeaks or areas of friction? Does the door seem to slow down or get stuck along the way? If so, you'll know that section of track is misaligned.
To fix this problem, loosen the screws that hold the track to its frame, gently tap the track back into the proper position, then retighten the screws. A level and a rubber mallet might help.
9. There's an Unseen Obstacle
To prevent injury, garage doors automatically reverse if they come into contact with an obstacle. When the door closes halfway but then reverses for no apparent reason, this may be a sign that something is preventing it from closing, something that you can't see. Check the tracks for stuff like dirt, rocks, bits of trash, or other debris. Give the tracks a wipe-down to dislodge anything that might be getting in the way.
10. "Disconnect" Has Been Switched
Every garage door opener comes with a disconnect switch, cord, or knob that allows you to work the door manually in case of a power outage. Check to make sure that you haven't accidentally disconnected the motor.
11. It's Locked!
This one falls squarely into the category of user error. If the motor is running, but the door doesn't budge, it's time to ask yourself if it might be locked. Check to see if any metal parts have slid down to bar access. If there are, locate the locking knob or handle and use it to disengage the lock.
FAQs About Garage Doors That Won't Open or Shut
Why won't my garage door open all the way?
Sometimes, when it gets stopped halfway shut or open, it might be that the springs are broken (see #3), or the limit setting needs an adjustment (see #7). If all else fails, you might try spraying the track with lubricant.
The garage door motor is running, but the door isn't opening. What's wrong?
Check the photo sensors' alignment (tip #1 above) or the cables to see if they're broken or if the tension is off (#4).
Why isn't my garage door wall switch working?
Check the LED light to see if it's giving you any malfunction information, and check the outlet for power. It could be a problem with wiring or with the logic board. See the video below for more information.
Why won't the garage door close or open with the remote?
Your remote is probably malfunctioning. See tip #6 above for a list of possible issues to troubleshoot.
What if I can't get into my garage?
Maybe the battery died, or a spring broke, but you can't get into the garage to even see what the problem is. If the garage door is the only way in or out, or if you can't find the key to the door, you'll have to either find a way to break in or call a locksmith. As a preventative measure, it's smart to keep a spare key or install an emergency key release that would allow you to release the emergency disconnect to the operator so you can manually raise the door.
How to Open Your Garage Door Manually
- Get a ladder.
- Find the red cord on the mechanism that's hooked to a lever. This is the emergency disconnect, and it should release the door and enable you to move it.
- Yank the cord, then get down off the ladder.
- Lift the door with both hands. If it doesn't move, go back up to pull the red cord again.
- Once you have it open, you'll have to prop it up with something to prevent it from sliding down again.
If you're outside and can't get into a closed garage, you don't have many options. You may have to call a locksmith or find a way to break in. As a preventative measure, it's smart to install an emergency key release that allows you to release the emergency disconnect remotely so you can manually raise the door.

Any thoughts anyone?
Essie on April 20, 2020:
Hi I have a Genie Garage door opener 1/2 HP,MODEL H6000-07/M
Recently this door opener started acting funny. I don't have any problem for closing the door from inside using key pad or remote from outside. when I want to open from inside of garage using the key pad,if I push the button and release it the door goes up only a few inches and stops, but if I continue holding the button until it is up about half way it continues going up without holding the button. When I use the remote from outside, the door goes up only a few inches and stops, it does not go up even if I continue pushing remote button. By the way this problem started after a week of cold weather and rain.
Mike on March 20, 2020:

Garage Door opened, no problem, when we went to close it, it would not close, from either, car remote, outside remote, or inside box. The motor light does not flicker as if something is blocking it, everything appears normal. Light turns on at box as if it's opening.

Randy on November 17, 2019:
Our opener won't work when the temperature of the garage is below 35 degrees. It'll just go up 10 inches or so and then stop. If I hold the remote in my hand AND continuously push up on the wood garage door then it'll keep humming/work until it's all the way up. When remote is pushed again to close -- it'll close easily/normally.

Rick on February 22, 2018:
We arrived at a rental property and tried to open garage door to get our vehicle in so we could unload luggage, etc. Could not open from outside. Went into house and, from inside garage, tried automatic opener but this did not work. So in trying to open the door manually, I reached up and pulled on the red cord attached to a lever. What I could not see, and was not expecting, is that the rope was frayed through almost completely. The rope broke when I applied some weight to it, sending me backwards onto the floor of the garage.
My question is, was there another way I could have opened the garage door manually, thereby avoiding what happened?
John on February 16, 2018:

That is the only way in, so I can't go in the garage from inside the house. I can't pull the cord to release the belt drive. How do I open it now? I never did run wires to the manual button into the house. I have to use the opener. Only have one I can find now. It is not working. I need in there now.

jim on September 04, 2017:
The garage door will freeze in various positions. The opener just quits. Neither the remote nor the wall switch will work.
The only way to unfreeze it is to disconnect, then reconnect the power. But it happens again, and again. Is there a circuit board or part that is homeowner friendly to replace?

Our garage door won't open, three red lights are lit
Ed on September 01, 2016:
Check the release. There is a cord that you pull that disengages the door from the opener. When it is pulled the trolley that rides along the bar will move back and forth but the door doesn't move. All you need to do is push the release lever back up.
Victor on August 27, 2016:
I have the exact same issue. Only difference is that my opener is screw driven and not chain. I would love a response to this problem. Thank you.
Tony on August 27, 2016:
HI, my garage door does not open. The motor runs and the shaft turns, but seems it is not engaging the chain. It does close when opened manually.
Please advise on what the problem may be.
