A garage door that won’t close all the way can be more than a minor inconvenience; it compromises your home’s security and poses safety risks. Many homeowners have encountered the frustrating problem of their garage door beginning to close but then immediately reversing direction. This post will explain the common causes of this issue, how you can troubleshoot it, and when you may need professional help. If you’re in Calgary, Okotoks, or Airdrie, Garage Door Repairman is here to assist with any garage door repairs and maintenance needs.
Understanding the Basics: How Your Garage Door Works
Garage doors are complex systems that rely on a balance of mechanical and electronic parts working together. A typical garage door operates with a motorized opener connected to a system of springs, cables, tracks, and sensors. When everything is working correctly, the door smoothly moves up and down. However, if there’s an issue with even one of these components, the door might start to close but then reverse itself.
Most garage doors come with built-in safety mechanisms, including sensors that detect obstructions and prevent the door from closing on people or objects. While these features are essential for safety, they can also be a source of trouble if they become misaligned or dirty. Let’s dive deeper into common reasons why your garage door might start closing only to reopen after a short distance.
Common Reasons Why Garage Doors Reverse After Starting to Close
Several factors can cause your garage door to begin closing, then reverse and open again. Here are some of the most common culprits:
1. Obstruction in the Door’s Path
Garage doors come equipped with sensors, usually near the floor, that detect if something is in the way. If these sensors sense an obstruction, the door will automatically reverse to prevent potential injury or damage.
- Troubleshooting Tip: Look for any items or debris that might be blocking the sensors, such as toys, tools, or dirt. Remove anything in the way, and see if the door functions correctly.
2. Dirty or Misaligned Safety Sensors
Over time, garage door sensors can become dirty or misaligned, causing them to send false signals that an obstruction is present. This will cause the door to reverse prematurely, as the system thinks something is blocking the path.
- Troubleshooting Tip: Clean the sensor lenses with a soft cloth to remove any dirt or dust. Also, ensure the sensors are aligned properly—most systems have indicator lights on the sensors. If the lights are not steady, adjust the sensors until they are aligned.
3. Issues with the Limit Settings
The garage door opener has limit settings that control how far the door travels when opening and closing. If these settings are incorrect, the door might think it has hit an obstacle and reverse direction.
- Troubleshooting Tip: Check your garage door opener’s manual to locate the limit adjustment knobs, often labeled as “up” and “down.” Adjust these settings gradually and test the door after each adjustment to ensure the door closes fully.
4. Broken or Damaged Springs
Springs play a crucial role in your garage door’s operation, providing the necessary counterbalance for smooth movement. If a spring breaks or is worn out, the door may not move as it should, potentially causing it to reverse direction during closing.
- Troubleshooting Tip: Check for signs of wear or damage on the springs. Replacing springs can be dangerous, so it’s best to call a professional if you suspect an issue. Garage Door Repairman serves Calgary, Okotoks, and Airdrie with safe, expert spring repairs.
5. Damaged or Dirty Tracks
The tracks that guide your garage door can accumulate dirt or suffer from physical damage. When debris builds up or the track becomes misaligned, the door might encounter resistance, which triggers it to reverse.
- Troubleshooting Tip: Inspect the tracks for any visible debris, dents, or bends. Use a damp cloth to wipe away dirt and check for any parts that might require straightening. If the track is heavily damaged, contact Garage Door Repairman for expert repair service.
When to Call a Professional
While minor issues like cleaning sensors or realigning tracks can often be handled by homeowners, certain repairs are best left to professionals. If you’ve tried troubleshooting but your garage door still won’t close, it may be time to reach out to a garage door specialist.
Situations Requiring Professional Help:
- Broken or Worn-Out Springs: Handling springs can be dangerous due to the high tension they hold.
- Persistent Sensor Issues: If sensors are repeatedly malfunctioning, there may be an electrical issue.
- Faulty Opener: An aging or malfunctioning opener may need to be repaired or replaced.

Tips for Maintaining a Healthy Garage Door System
To avoid common garage door problems, a little preventative maintenance goes a long way. Here are some helpful tips to keep your garage door functioning at its best:
1. Regularly Inspect and Clean Sensors
Since sensors are often the root cause of many garage door issues, regularly inspect and clean them. Make this part of your monthly routine to ensure they remain free of dust and debris.
2. Lubricate Moving Parts
Lubricate the tracks, rollers, springs, and hinges with a silicone-based lubricant. This helps reduce friction and ensures smoother operation.
3. Test the Reversal Mechanism
Regularly test the reversal mechanism by placing an object, like a small block of wood, in the door’s path. The door should reverse as soon as it contacts the object. This safety feature ensures the door won’t close on people, pets, or belongings.
4. Inspect Springs and Cables
Check for wear on the springs and cables, but avoid handling them yourself due to the tension involved. Call Garage Door Repairman for any necessary repairs to these components.
5. Check the Door Balance
A well-balanced door is easier on the opener and ensures smooth operation. Disconnect the opener and manually lift the door halfway; if it stays in place, the balance is good. If not, consult a professional for help with rebalancing.
