Common Reasons Why A Garage Door Won’t Close

Garage doors not closing can be caused by various factors, such as sensor misalignment/blockage, malfunctioning openers or remote controls, broken springs or cables, obstructions blocking the door, and misaligned tracks. To ensure easy access and maintenance in such situations, consider installing a BA-DW-5040 Flush with Drywall Bead Flange Access panel near your garage door mechanism. This access panel provides a convenient and concealed way to access the inner workings of your garage door for troubleshooting and repairs, ensuring a smooth and functional garage door operation.

Sensor Blockage Or Misalignment

One of the most common reasons why a garage door won’t close is due to sensor blockage or misalignment. Garage doors are equipped with safety sensors, also known as photo eye sensors, that detect obstructions in the path of the door and prevent it from closing on objects or people.

A blocked photo eye sensor can be caused by dirt, debris, or even spiderwebs covering one or both of the lenses. Misaligned sensors occur when one or both units have been inadvertently knocked out of position, interrupting their line-of-sight connection.

In either case, this will cause the garage door opener to assume that there is an obstruction in its path and prevent it from closing. To resolve this issue, carefully inspect each sensor for any signs of blockage and clean them if necessary.

Furthermore, ensure that they are properly aligned by checking if their LED lights are solidly lit; flashing lights indicate misalignment which requires adjusting until they regain a steady glow.

Malfunctioning Opener Or Remote Control

Another common reason why a garage door won’t close is due to a malfunctioning opener or remote control. If the opener or remote fails to send the signal to close the door, it could be due to dead batteries in either device or an issue with the transmitter itself.

Alternatively, there may be electrical issues preventing communication between devices. In some cases, simply resetting or reprogramming the remote and/or opener can solve this problem.

However, if these solutions fail, replacement of either device may be required.

Broken Springs Or Cables

If your garage door won’t close, you might have broken springs or cables. These are important components that help balance the weight of the door as it opens and closes.

One sign of a broken spring is if your garage door appears heavy to lift manually. You may also hear a loud noise when attempting to open the door using your remote control or wall switch.

A snapped cable can cause similar issues and could even result in further damage to other parts of the system if not addressed promptly by a professional technician.

Remember to schedule regular maintenance checks for your garage door system since worn-out springs or cables can lead to bigger problems like malfunctioning safety features or even total failure of the entire mechanism over time.

Obstruction Blocking The Door

One of the most common reasons why a garage door won’t close is due to an obstruction blocking the door’s path. This can be anything from a piece of debris on the tracks to something as simple as a child’s bike left in front of the door.

When an obstruction is present, it prevents the safety sensors from sending signals to each other to let them know that it’s safe for the garage door to close.

To solve this problem, inspect your garage area for any obstructions in the way of your garage door. Make sure that there are no items or debris on your tracks or near your safety sensors, which could be causing interference with their signals.

Misaligned Tracks

Misaligned tracks are another common reason why a garage door won’t close. The metal tracks that guide the garage door can get bent or knocked out of alignment over time, preventing smooth movement and causing the door to get stuck.

To troubleshoot this issue, it’s important to visually inspect the tracks for any signs of misalignment or damage. If there are gaps between the rollers and rails or if they appear twisted, it’s likely that you have a track alignment issue.

Regular maintenance checks conducted by an experienced technician can catch misaligned tracks before they become major problems.

Troubleshooting Tips To Fix A Garage Door That Won’t Close

To fix a garage door that won’t close, homeowners can try checking the sensor alignment and cleanliness, resetting the opener or remote control, inspecting and replacing broken springs or cables, removing obstructions, and adjusting the tracks.

Check Sensor Alignment And Cleanliness

One of the most common reasons a garage door won’t close is due to blockage or misalignment of the photo-eye sensors. These sensors are responsible for detecting any obstacles in the path of the garage door and preventing it from closing if anything is detected.

To fix this issue, first, ensure that nothing is blocking the sensors’ line of sight and clean them if they’re dirty.

Regular maintenance checks can prevent future issues with your garage door. Inspect your garage door on a monthly basis for proper functioning, cleanliness, obstructions, and signs indicating that repair may be necessary (like fraying cables, worn pulleys).

Reset The Opener Or Remote Control

If your garage door won’t close and you suspect that the cause is a malfunctioning opener or remote control, try resetting it first. Check if the batteries in your remote are dead or low, which can prevent it from sending a signal to the opener.

To reset the opener, locate its power source and unplug it for at least 30 seconds before plugging it back in. This resets its programming and may help resolve any issues causing the door not to close properly.

Try operating your garage door again using both the remote control and wall-mounted buttons to see if this has fixed the problem.

Regular maintenance of your garage door system can prevent malfunctioning openers or remotes from occurring regularly so ensure that all parts are well-maintained on time.

Inspect And Replace Broken Springs Or Cables

Broken springs or cables are another possible culprit if your garage door won’t close. These components play a crucial role in lifting and lowering the door, so any damage can result in malfunctioning operation.

To fix this issue, you’ll need to inspect the springs and cables for damage and replace them if necessary. It’s important to note that attempting to fix these components on your own can be dangerous due to the high tension involved.

We recommend calling a professional garage door technician who has specialized tools and experience with these types of repairs.

Remove Obstructions

Removing obstructions is an essential step in troubleshooting a garage door that won’t close. Small items such as toys, boxes, or trash cans can easily block the path of the garage door and prevent it from closing properly.

Ensure there are no large objects (such as furniture) blocking the sensors at either side of the door frame. Remember also to check above and below ground level for any other types of obstruction that might be interfering with your garage door’s closure mechanism.

Adjust The Tracks

Misaligned tracks can also cause your garage door to not close properly. If you notice that the door is crooked or rubbing against the tracks, it’s time for an adjustment.

To do so, use a level tool to ensure that both tracks are parallel and at the same height. Then, loosen the screws holding the track in place and adjust it accordingly before tightening them back up.

Ignoring this problem can lead to more damage down the line and even put safety at risk since an unbalanced door can suddenly come off its track while opening or closing.

When To Call A Professional For Help

If you encounter complex repairs, safety concerns, or unsuccessful DIY repairs, it’s crucial to call a professional for help with your garage door issues.
