7. Regular Maintenance: To prolong the life of your garage door springs and prevent future issues, it is important to maintain them properly. Apply a silicone-based lubricant to the springs periodically to reduce friction and prevent corrosion. Regularly inspect the springs for signs of wear or damage.

Remember, working with garage door springs can be dangerous and should be approached with caution. If you are unsure or uncomfortable with the inspection and replacement process, contact a professional garage door technician who can safely and correctly replace the broken springs.

By examining and replacing broken garage door springs, you can restore the proper balance and functionality of your door, eliminating the issue of unexpected openings and ensuring the safe operation of your garage door system.

Inspect and Repair Garage Door Tracks

If your garage door keeps opening after closing, it’s important to inspect and repair the garage door tracks, as issues with the tracks can interfere with the smooth operation of the door. Damaged or misaligned tracks can prevent the door from closing completely, causing it to reopen unexpectedly.

Follow these steps to inspect and repair the garage door tracks:

1. Visual Inspection: Begin by inspecting the tracks visually. Look for any signs of damage, such as bends, dents, or gaps in the tracks. Check for any loose or missing mounting brackets or hardware.

2. Track Alignment: Observe if the tracks are properly aligned. Use a level to ensure that the tracks are plumb and straight. Misaligned tracks can cause the door rollers to bind or derail, resulting in improper functioning.

3. Clean the Tracks: Clear any dirt, debris, or obstructions from the tracks. Use a damp cloth or a soft brush to remove any buildup. Ensure that the tracks are clean and free from any obstacles that could obstruct the door’s movement.

4. Check Roller Condition: Inspect the rollers that glide along the tracks. Look for signs of wear, damage, or misalignment. If any rollers are worn out or damaged, they may need to be replaced. Lubricate the rollers with a silicone-based lubricant to ensure smooth operation.

5. Verify Vertical Alignment: The tracks should maintain a consistent vertical alignment from top to bottom. Use a level to check if the tracks are vertical and parallel to each other. Adjust the tracks if they are out of alignment.

6. Correct Horizontal Alignment: The horizontal alignment of the tracks is also crucial for proper door operation. Ensure that the tracks are parallel to the garage wall, following the same horizontal plane. Adjust the tracks if needed until they are properly aligned.

7. Repair Bent Tracks: If the tracks are bent or misshapen, attempt to straighten them using a pair of pliers or a track straightening tool. Be gentle, as excessive force may further damage the tracks. Severe or irreparable track damage may require professional assistance or replacement.

8. Tighten Loose Hardware: Check all mounting brackets, bolts, screws, and nuts along the tracks. Tighten any loose hardware as needed to secure the tracks in place.

9. Test the Door Operation: After inspecting and repairing the tracks, test the garage door’s operation. Close and open the door multiple times to ensure it moves smoothly along the tracks without any issues.

If you encounter difficulties or the problem persists despite your efforts, it is recommended to seek professional assistance from a qualified garage door technician. They have the expertise and tools to repair or replace damaged tracks and ensure the proper alignment of your garage door system.

By inspecting and repairing the garage door tracks, you can eliminate any issues that may cause the door to open unexpectedly after closing. Properly aligned tracks are crucial for smooth and reliable door operation, enhancing the overall functionality and safety of your garage door.
