Introduction
The garage door is one of the most commonly used moving components in your home. So, when it suddenly stops closing mid-way, it can be frustrating and even pose a security risk. A garage door that stops before closing completely usually signals an issue with the sensors, tracks, or opener settings.
Understanding why this happens and how to fix it can save you time, money, and the hassle of dealing with an inoperable door. In this guide, we’ll walk you through the common reasons why your garage door might be stopping mid-close and provide step-by-step troubleshooting solutions.
1. Understanding How a Garage Door Works
Before jumping into fixes, it helps to understand the key components that make your garage door function properly:
- Garage Door Opener – The motorized unit that controls the opening and closing mechanism.
- Safety Sensors – Infrared sensors at the bottom of the door detect obstructions and prevent accidents.
- Torsion or Extension Springs – Provide the tension needed to lift and lower the door smoothly.
- Cables and Pulleys – Work with the springs to balance the door.
Any malfunction in these parts can cause the door to stop midway during operation.
2. Common Reasons Why Your Garage Door Stops Closing
2.1. Blocked or Misaligned Safety Sensors
Most modern garage doors have infrared safety sensors near the bottom of the door frame. These sensors prevent the door from closing if an object is detected in its path.
Signs of sensor issues:
- The garage door stops and reverses immediately.
- The sensor lights are blinking or off.
- Dirt or debris is covering the sensor lenses.
Fix:
- Wipe the sensors clean with a soft cloth.
- Check if they are misaligned and adjust them until the LED lights are solid.
2.2. Obstructions in the Door’s Path
Even small objects, such as leaves, tools, or toys, can trigger the safety mechanism and stop the door from closing.
Fix:
- Inspect the area along the tracks and floor.
- Check if dirt or debris has accumulated in the tracks.
2.3. Broken or Worn-Out Springs
Garage doors rely on tension springs to open and close smoothly. If a spring breaks, the door may struggle to close properly.
Signs of broken springs:
- The door closes partway and then stops.
- A loud bang was heard before the issue started.
Fix:
- Visually inspect the springs for gaps or breaks.
- Avoid DIY repairs, as broken springs can be dangerous.
- Contact a professional if a spring is damaged.
2.4. Damaged or Warped Tracks
Bent or misaligned tracks can prevent smooth movement, causing the door to get stuck.
Fix:
- Look for visible bends or warps in the tracks.
- Use a rubber mallet to gently straighten minor bends.
2.5. Garage Door Opener Issues
Sometimes, the issue isn’t mechanical but rather a problem with the opener’s settings.
Fix:
- Adjust the close-limit switch if the door is stopping too soon.
- Reset the garage door opener by unplugging it for a few minutes.
- Replace the batteries in your remote control.
2.6. Remote Control or Wall Switch Malfunctions
If the door is unresponsive to commands, the issue might be with the remote or wall switch.
Fix:
- Replace the remote’s batteries.
- Ensure the opener’s antenna is intact and not obstructed.
- Test the wall switch to determine if the problem is with the remote.
3. Step-by-Step Troubleshooting Guide
3.1. Checking the Sensors
- Wipe down the lenses.
- Adjust their alignment.
- Ensure they are securely connected to the power source.
3.2. Inspecting the Tracks and Rollers
- Look for bends or gaps in the tracks.
- Lubricate the rollers to reduce friction.
3.3. Testing the Garage Door Opener
- Adjust the force settings on the opener.
- Reset the unit if necessary.
3.4. Examining Springs and Cables
- Look for visible signs of wear.
- Avoid DIY repairs on springs – call a professional if needed.
4. When to Call a Professional
If you notice broken springs, damaged cables, or persistent issues despite troubleshooting, it’s best to call a professional technician. Repairs involving high-tension springs can be dangerous and require specialized tools.
5. Preventative Maintenance Tips
- Clean sensors and tracks regularly.
- Lubricate moving parts every few months.
- Perform a monthly safety test.
- Schedule professional maintenance annually.
