Whether it’s stuck halfway or refuses to budge, a malfunctioning garage door can be more than just an inconvenience—it can pose a security risk to your home. In this article, we’ll cover the most common reasons why your garage door won’t close, how to fix the issues, and when to call a professional for help.
A garage door that won’t close properly might be caused by anything from simple sensor problems to more complex mechanical failures. If you’re experiencing issues with your garage door, this detailed guide will help you understand why it’s happening and what you can do to resolve it. Let’s dive into the reasons your garage door might not be closing and the best solutions to get it back in working order.
Common Reasons Why Your Garage Door Won’t Close
Several issues can cause your garage door won’t close situation. Identifying the root cause is essential to fixing the problem quickly and avoiding further complications. Below are some of the most common reasons your garage door may refuse to close.
1. Misaligned or Blocked Safety Sensors
The safety sensors (photo-eye sensors) located near the bottom of the garage door tracks are one of the most common culprits when the garage door won’t close. These sensors are designed to prevent the door from closing if an object or person is in its path. However, if the sensors become misaligned or dirty, they might mistakenly detect an obstruction when there’s nothing in the way.
How to Fix It:
- Inspect the sensors to make sure they are aligned correctly.
- Clean the lenses of the sensors with a soft cloth to remove any dirt or debris.
- Ensure there’s nothing physically blocking the sensor’s line of sight.
- If the sensor wires appear damaged, you may need to replace them.
2. The Garage Door Opener’s Limits Are Incorrectly Set
Garage door openers have limit settings that tell the door how far it should move to fully close. If these settings are incorrectly programmed, the door might stop short of the ground, thinking it has completed its cycle.
How to Fix It:
- Locate the limit adjustment knobs on your garage door opener.
- Adjust the settings to increase or decrease the downward travel of the garage door.
- Test the door after each adjustment to ensure it closes fully.
3. Obstruction in the Tracks
Even a small obstruction in the garage door tracks can prevent the door from closing. Dirt, debris, or physical damage to the tracks can cause the rollers to get stuck, stopping the door from operating smoothly.
How to Fix It:
- Inspect the tracks for any obstructions or debris.
- Clear away any dirt or objects that may be blocking the path.
- If the tracks are bent, carefully straighten them with a pair of pliers.
4. The Garage Door Remote or Wall Switch Malfunction
If your garage door won’t close when you press the remote or the wall switch, the problem might lie in the control system. The remote battery could be dead, or there could be an issue with the wiring in the wall switch.
How to Fix It:
- Replace the battery in the remote and see if that resolves the issue.
- Check the wall switch wiring to ensure it’s properly connected and not damaged.
- If the remote or switch still doesn’t work, you may need to reprogram the remote or replace it.
5. Broken Garage Door Springs or Cables
Garage door springs and cables are responsible for the smooth lifting and lowering of the door. If a spring or cable is broken, the door might not close properly—or at all. Broken springs are especially dangerous, as they carry a significant amount of tension.
How to Fix It:
- Inspect the garage door springs and cables for any visible damage or breakage.
- If you notice a broken spring or cable, do not attempt to fix it yourself—this is a job for a professional due to the high tension these parts carry.
6. The Door Is Locked
It might sound simple, but sometimes the reason a garage door won’t close is that it’s locked! Many garage doors have a manual lock mechanism that can be engaged accidentally.
How to Fix It:
- Check to see if the manual lock is engaged.
- If it is, unlock the door using the handle or switch located on the inside of the garage.
7. Damaged Garage Door Rollers
Rollers allow the garage door to move smoothly along the tracks. If the rollers are damaged or worn out, they can cause the door to become stuck or fail to close all the way.
How to Fix It:
- Inspect the rollers for signs of wear or damage.
- If the rollers are worn out, they will need to be replaced.
Troubleshooting Your Garage Door: Step-by-Step Solutions
Now that you’re familiar with some of the most common reasons why a garage door won’t close, let’s dive into a step-by-step troubleshooting guide. By following these instructions, you can potentially resolve the issue quickly and prevent it from escalating into a more serious and costly repair.
Step 1: Check the Safety Sensors
The safety sensors are one of the most common causes of a garage door that won’t close. These sensors are located near the bottom of the door frame, and they need to be properly aligned to allow the door to close. Here’s how to check and fix them:
- Inspect Alignment: Make sure both sensors face each other directly and are positioned at the same height. Misalignment will cause the door opener to assume something is blocking the door, preventing it from closing.
- Use a Level: To ensure the sensors are perfectly aligned, use a level to check that they are set evenly.
- Clean the Sensors: Dirt, dust, or cobwebs can obstruct the sensors. Gently wipe them clean with a soft cloth to remove any debris that might interfere with their operation.
Step 2: Inspect the Garage Door Tracks
The next step is to inspect the garage door tracks, as obstructions or damage can stop the door from closing smoothly.
- Clear the Tracks: Look along both tracks to ensure there are no obstructions such as dirt, small objects, or debris that could be blocking the door’s movement.
- Check for Bends: Examine the tracks for any bends or warping. A bent track can throw the door off balance, making it difficult or impossible for it to close properly. If you notice any slight bends, carefully use a pair of pliers to straighten them.
Step 3: Test the Garage Door Opener Limits
Your garage door opener has limit settings that control how far the door moves when opening or closing. If these settings are incorrect, the door might not close all the way.
- Locate the Adjustment Screws: The limit settings can be found on the motor housing of the opener. There are usually two screws or knobs—one for the “up” limit and one for the “down” limit.
- Make Small Adjustments: Turn the adjustment screw for the “down” limit in small increments to allow the door to close fully. Test the door after each adjustment to see if it now closes properly.
Step 4: Check the Remote and Wall Switch
If your garage door isn’t responding to the remote or wall switch, the issue might be with the remote control, the switch, or the wiring.
- Replace the Remote Battery: The most common culprit for a non-responsive remote is a dead battery. Replace the battery and try again.
- Inspect the Wall Switch: If the remote works but the wall switch doesn’t, check the wiring connected to the wall switch for any visible damage or loose connections. Tighten the wiring if necessary.
- Reprogram the Remote: If the remote still isn’t working, it might need to be reprogrammed. Follow the instructions in your garage door opener’s manual to reprogram the remote.
Step 5: Look for Broken Springs or Cables
If none of the previous steps resolve the issue, the problem may lie with the springs or cables. These components are essential for the smooth operation of the garage door, and if they’re broken, the door won’t close properly.
- Inspect the Springs and Cables: Look for visible signs of wear, rust, or breakage in the springs or cables. However, do not attempt to repair or replace these yourself. Garage door springs and cables are under high tension, and handling them without proper tools and expertise can be dangerous.
- Call a Professional: If you suspect the problem is with the springs or cables, it’s time to contact a professional garage door repair technician. A trained garage door repair expert will be able to safely repair or replace the springs and cables, restoring your door to full functionality.
Following these troubleshooting steps, you can often identify and fix minor garage door issues before they become major problems. Cleaning sensors, adjusting tracks, and testing the opener’s limits are simple tasks that can save you time and money. However, if you encounter more serious issues, such as broken springs or cables, it’s crucial to leave these complex repairs to professionals. With the help of experts, you can ensure the safe and reliable operation of your garage door.
5 Common FAQs About Garage Door Won’t Close
Here are the five most common questions people ask regarding why their garage door won’t close:
1. Why does my garage door start to close and then reverse?

2. Can I fix a garage door that won’t close on my own?
Yes, in many cases, you can fix a garage door that won’t close on your own. However, issues like broken springs or cables should be handled by a professional due to the danger they pose.
3. How can I tell if my garage door sensors are bad?
If the door won’t close or stops partway down and reverses, the sensors could be faulty. You can also tell if one or both sensors are bad if the LED light on the sensors is blinking or not lit.
4. How much does it cost to repair a garage door that won’t close?
The cost to repair a garage door that won’t close depends on the cause of the problem. Sensor adjustments or track cleaning are inexpensive, but replacing springs or cables can range from $150 to $350 or more.
5. Do I need to replace my garage door opener if it won’t close?
Not necessarily. Most garage door openers last for many years. Before replacing the opener, troubleshoot the sensors, track alignment, and remote batteries. If the problem persists, you might need a new opener.
Conclusion
A malfunctioning new garage door that won’t close can be frustrating, but basic troubleshooting can often resolve the issue.
