Why Won't My Garage Door Won’t Close All the Way?

One of the most common issues homeowners face with their garage doors is when they won't close all the way. This problem can be frustrating and inconvenient, leaving your garage exposed to the elements and potential security risks. Plus, most homeowners need to then manually close and manually open the garage door. We know you might not have a ton of experience with this topic, but having a basic understanding of the issue can help you troubleshoot and address the problem effectively. We've outlined some possible reasons why your garage door won't close all the way:

  • Misaligned safety sensors: If the safety sensors located at the bottom of your garage door track don't properly align, the door may not close entirely as a safety precaution.
  • Malfunctioning garage door openers: A faulty or malfunctioning garage door opener can prevent the door from closing all the way. Issues like worn-out gears, motor problems, or faulty wiring can cause the opener to malfunction.
  • Broken or worn-out springs: Garage door tension springs play a crucial role in the garage door opening and closing mechanism. If the springs are broken or worn out, they can affect the balance and movement of the door which leads to incomplete closure.
  • Obstructions in the door's path: Any objects, debris, or obstructions in the garage door's path can trigger the safety mechanism, preventing the door from closing all the way.

As long as you identify the specific reason behind your garage door not closing properly, you can follow the troubleshooting steps mentioned earlier to resolve the issue and ensure the smooth operation of your garage door.

10 Easy Steps to Fix a Garage Door That Refuses to Close

Step 1: Check for Obstructions

One of the first things you should do when your garage door won't close is to check for any obstructions in its path. Objects such as tools, debris, or even small rocks can prevent or block the door from closing correctly.

Carefully inspect the area around the garage door tracks, bottom seal, and floor to ensure there are no items hindering the door's movement. Remove any obstructions that you find and test the door again.

In case there's a damaged or severely worn-out garage door that's causing repeated obstruction issues, it might be time to consider replacing it with a new one. Upgrading to a new garage door can provide improved functionality, enhanced security features, and better insulation to give you peace of mind.

Step 2: Inspect the Safety Sensors

Modern garage doors are equipped with safety sensors near the bottom of the tracks to prevent accidents and ensure safe operation. If these sensors are misaligned, dirty, or obstructed, they can prevent the door from closing.

Start by checking if the sensors are properly aligned and facing each other. Clean the sensors with a soft cloth to remove any dirt or debris that might be blocking the sensor's signal.

If the sensors are damaged or non-functional, consider replacing them with new ones. Installing new safety sensors can help restore your garage door's functionality and give you an extra level of safety.

Step 3: Verify the Remote Control Batteries

When your garage door won't close with the remote control, it could be due to weak or dead batteries. Inspect the remote control and check the battery compartment. If the batteries are low or dead, replace them with new ones.

Ensure that the batteries are properly inserted and have a good connection. After replacing the batteries, try operating the door again using the remote control. If the issue persists, you might need to reprogram the remote control to synchronize it with the garage door opener.

If the garage door opener is outdated or beyond repair, it's an opportunity to invest in a new and more advanced opener system. A new garage door opener can offer improved features, such as smartphone connectivity, photo eye sensors, and enhanced security protocols.

Step 4: Reset the Garage Door Opener

If your garage door opener isn't functioning properly and you see light flashes coming from the sensor, resetting it can often resolve the issue and it can save money on repairs. Start by locating the reset button on the opener unit, which is usually a small, red, or yellow button.

Press and hold the reset button for a few seconds until the lights on the opener blink or the unit makes a beeping sound. This action will reset the opener's settings and clear any temporary glitches. After resetting the opener, test the door to see if it closes properly.

If these troubleshooting tips don't work and your garage door opener continues to malfunction or shows signs of significant wear and tear, you might need to replace it with a new one. Upgrading to a new garage door opener can offer improved performance, quieter operation, and advanced safety features, ensuring your garage door operates smoothly and reliably.

Step 5: Lubricate the Moving Parts

Regular lubrication of the moving parts is essential to ensure the smooth and efficient operation of your garage door. Using a silicone-based lubricant, apply a thin coat to the hinges, rollers, springs, and tracks.

Lubrication helps reduce friction and wear, preventing components from seizing or sticking. It's important to avoid using WD-40 or oil-based lubricants as they can attract dirt and debris, causing more harm than good.

If the moving parts are rusted, damaged, or worn out beyond repair, you might need to replace them. Investing in new high-quality hinges, rollers, springs, and tracks can significantly improve the performance and longevity of your garage door, providing a smoother and quieter operation.

Step 6: Adjust the Limit Switches

The limit switches on your garage door opener control the door's travel distance and ensure it stops in the correct position. If your garage door won't close all the way, the limit switches may need adjustment. Find the limit switch adjustment screws on the opener unit.

Turn these screws incrementally to modify the open and close limits of the garage door. Carefully adjust the switches until the door closes completely and stays closed without reversing or leaving a gap.

If the limit switches are malfunctioning or cannot be adjusted properly, consider replacing the opener or consult a garage door repair professional for further assistance. A new garage door opener with advanced limit switch technology and limit settings gives you precise control over the door's movement and ensures accurate closing.

Step 7: Tighten Loose Hardware

Over time, the constant movement of your garage door can cause the hardware to become loose. Loose bolts, nuts, screws, and brackets can affect the alignment and smooth operation of the door. Be sure to inspect all the hardware components, including hinges, brackets, and tracks.

Using a wrench or screwdriver, tighten any loose hardware that you find. Be cautious not to overtighten, as it can strain the components.

If you notice that the hardware is severely damaged or stripped, you might need to replace specific parts. Upgrading to new, sturdy hardware ensures a secure and properly aligned garage door, preventing future issues.

Step 8: Replace Worn-Out Rollers

The rollers on your garage door facilitate smooth movement along the tracks. Over time, these rollers can wear out, become misaligned, or develop flat spots, causing the door to operate unevenly or make excessive noise.

Inspect the rollers carefully, looking for signs of wear or damage. If you notice cracks, chips, or significant wear, you'll want to replace the worn-out rollers.

Upgrading to high-quality nylon or steel rollers can greatly improve the performance and lifespan of your garage door. These rollers provide smoother and quieter operation while reducing the strain on other components. Consider replacing the rollers with new ones to ensure optimal functionality and minimize future repairs.

Step 9: Examine the Door Tracks

The tracks guide the movement of your garage door and play a crucial role in its smooth operation. Inspect the tracks for any signs of damage, such as bends, dents, or misalignment. Damaged tracks can hinder the door's movement and prevent it from closing correctly.

If you notice minor bends or misalignment, you can attempt to gently straighten the tracks using a rubber mallet or a piece of wood. However, if the tracks are severely damaged or misaligned beyond repair, it's advisable to replace them.

Installing new tracks can restore the right alignment and improve the operation of your garage door. Upgrading to high-quality tracks can provide enhanced durability and reduce the risk of future track-related issues.

Step 10: Seek Professional Help If Necessary

How frequently should I replace the rollers on my garage door?

The frequency of replacing rollers on a garage door depends on their condition and usage. On average, it's recommended to replace them every 5 to 7 years or if you notice signs of wear, such as cracks, flat spots, or excessive noise during operation. We recommend regular inspection and maintenance to help identify when the rollers must be replaced.

What type of lubricant should I use to lubricate the moving parts of my garage door?

For lubricating the moving parts of your garage door, we recommend using a silicone-based lubricant. Silicone lubricants are effective in reducing friction and preventing rust on metal components. Avoid using oil-based lubricants, which can attract dust and debris, leading to potential issues.

What should I do if my garage door starts closing but then reverses?

If your garage door starts closing but then reverses, you can try adjusting the sensitivity of the safety feature on the garage door opener. Look for adjustment screws or knobs on the opener unit and make minor adjustments until the door closes without reversing. You may also need to inspect the safety sensors and ensure they're aligned and free from obstructions so they work properly.
