Why Your Garage Door Opens a Little and Then Stops

Your garage door has two jobs: To open and to close. And when it doesn’t do one of the two properly, it can be pretty frustrating, like when your garage door opens a little then stops. And in the worst of cases, it can be the difference between you getting into your home or not. 

Luckily, garage systems are relatively straightforward, so once you start seeing consistent signs that your garage door won’t open, there are quite a few ways you can troubleshoot the garage door opener on your own before calling in a pro. But, many of the parts and pieces of a garage are heavy and technical, so if the issue is beyond a simple reset, relubrication, or realignment, you should be prepared to call in a pro.

1. Something’s Blocking the Sensors

First, let’s make sure there’s nothing blocking the door from doing its job. 

Sensors are some of the simplest yet most important factors that facilitate how a garage door opener works. Your door has two sensors—a transmitter and a receiver—that should be directly facing one another with no obstructions in the way. If the signal between the sensors is disrupted, the garage door can’t do its job.

A runaway toy or loose soccer ball could be the culprit, especially if you’re still dreaming up garage organization ideas but haven’t yet built a system to keep everything in its place. 

But if you don’t see anything in the way, your sensors may just be misaligned. This happens pretty often, especially if you have pets or little ones running around that could accidentally bump a sensor and disrupt the signal.

If you think that’s the cause or notice mismatched lights on your sensors, simply adjust the cameras until they point at one another. 

2. The Springs Are Broken

Springs are the muscles of your door, helping to lift and shut it. That means your garage door won’t open with a broken spring. Scope out the condition of your springs, looking for broken pieces, rust, loss of tension, or other signs of wear and tear that might signal a problem.

If you don’t see anything, but still suspect it’s your springs, conduct this test: Try physically lifting your garage door while it’s opening to see your added support gets the job done. If it opens while you’re lifting it but not on its own, the springs may not be taut enough to support the full weight of your door.

Even if you decide that your springs are the issue, don’t try to fix them on your own. Springs are very heavy and dangerous to mess with alone, so stick with a simple visual observation.

3. There’s an Issue With the Garage Door Track

A rusted, damaged, or frozen roller track could be the culprit if the springs and sensors all look fine. When it’s really cold, the metal on your track can seize up and disrupt its operation. Insulating your garage is a good way to avoid this issue down the road, especially if you live in an area that hits below freezing fairly often.

If the weather isn’t to blame, take a look at your track to see if anything looks out of place or broken. Things to look for include:

• Loose bolts

• Shaking door

• Bent rails

• Uneven tracks

If you notice anything, it’s best to call in a professional garage door installer to help. But if there’s nothing to see, try applying a lubricant like WD-40 to help loosen up any jammed or stuck pieces. Spray it along all the moving parts—including rollers, hinges, locks, and pivot points—to help the rollers run across the tracks.

Some experts recommend doing this every so often as part of your garage door tune-up process to keep things (literally) on track.

4. The Garage Opener’s Force Limit Needs to Be Adjusted

If the physical components of your garage door opener look OK, it may be something in the technical aspects of the machine itself, like the force limit.

The force limit is a setting on your opener that dictates how much power to use when opening and shutting the door. If your garage door won't open all the way, it may not have enough juice to do the job.

To adjust the setting, follow the instructions in your opener manual as each system has a different approach. Make the adjustments in small increments to avoid increasing it too much as this can quickly turn into a safety hazard.

Note: if you have to set the limit higher than the medium setting to get the door to open, there’s probably bigger garage door problems at hand and you should call a pro to do an inspection.

5. There’s a Motor Issue Within the Garage Opener

If you’ve tried everything else, you could have issues within the actual motor of your opener. There may be a fuse that’s down or a dead battery causing the delay in the opening and shutting.

A few warning signs that your motor may be the culprit include:

• Loud noises

• Vibrating opener

• Slow movements

• Blinking lights

• Inconsistent operation

Unfortunately if this is the case, there’s not much you can do on your own to fix it. You can try to reset your garage door opener to see if that corrects any bugs in the system, but it may not help if there’s an actual issue with the motor itself. If the reset doesn’t work, your best bet is to call a tech.

6. Something is Interfering With Your Radio Frequency

Garage door openers typically operate at a frequency of 300 to 390 MHz. Baby monitors, cordless telephones, and even your kid’s remote-controlled toys can operate off this same frequency—which can interfere with your opener’s operation.

You can test if it’s a garage door radio frequency problem by turning off potential sources of interference one by one and testing the opener each time. Your opener may also offer the ability to change frequency settings to avoid interference, or you can try resetting the system manually.

How to Open a Garage Door Manually

If all else fails, you can learn how to open a garage door manually by finding and using the manual release. While this won’t be a forever solution, it will let you get in and out of your garage while you wait for a repair or replacement. 

To open your garage door manually, locate the emergency release cord. This red rope will be hanging down from your garage door motor. Once you pull it, the lock will release on the door so you can lift it up manually. 

Pull the garage door down when you leave and re-engage the opener by pulling the release cord toward the door. This will lock your door so no one else can manually open it.

Fixing a Garage Door Yourself vs. Hiring a Pro

You can open and close your garage door manually for as long as you want if it doesn’t annoy you. But if (or when) you do have to repair your door or buy a new garage door opener, it can be costly. For that reason, you should try every troubleshooting option at your disposal before scheduling an appointment with a pro.

It's worth noting that DIYing garage door repair comes with major risks. Garage doors can weigh as heavy as 400 pounds, making them difficult and dangerous to handle. In addition, repairing them often requires quite a bit of technical experience, including electrical work. Hiring a local garage door repair technician to do the job safely is well worth the cost.

The average garage door repair cost ranges between $80 and $670. If a garage door opens a little and then stops, various parts of the door could need repairs. If the garage doors require replacement, the cost ranges between $250 and $1,000. Fixing the springs could cost between $180 and $350. If the sensor requires repair, the cost can range between $150 and $250.
