Garage Door Closes And Reopens

Garage Door Closes and Reopens

If your garage door closes and then immediately reopens, it can be a frustrating and confusing problem. There are several possible causes for this issue, and the solution will depend on the specific cause. Here are a few of the most common causes and their corresponding solutions:

1. Obstructions in the Door's Path

One of the most common reasons for a garage door to close and reopen is an obstruction in its path. This could be something as simple as a box or toy left on the floor, or it could be something more serious, like a misaligned track or a broken spring. To check for obstructions, carefully inspect the entire path of the door, both inside and outside the garage. Remove any obstacles and make sure the door is able to move freely.

2. Faulty Sensors

Garage doors are equipped with sensors that detect when there is an object in the way of the door. If these sensors are faulty, they may cause the door to close and reopen even when there is no obstruction. To test the sensors, place a small object, such as a piece of cardboard, in the path of the door. The door should stop closing when it reaches the object. If it does not, the sensors may need to be replaced.

3. Misaligned Tracks

The tracks that the garage door rolls on can become misaligned over time, which can cause the door to bind and reopen. To check for misaligned tracks, open the garage door and look for any gaps between the tracks and the rollers. If there are any gaps, the tracks will need to be realigned. This is a job that is best left to a professional.

4. Broken Spring

The springs on a garage door are responsible for lifting and lowering the door. If a spring breaks, the door will not be able to open or close properly. To check for a broken spring, look for any visible damage to the springs. You can also try to open the door manually. If the door is difficult to lift, it is likely that a spring has broken.

5. Faulty Wiring

The electrical wiring that powers the garage door opener can become damaged or faulty over time. This can cause the opener to malfunction, which can lead to the door closing and reopening. To check for faulty wiring, inspect the wires for any damage or fraying. If you find any damage, the wires will need to be repaired or replaced.

6. Incorrect Limit Settings

The limit settings on a garage door opener determine how far the door opens and closes. If the limit settings are incorrect, the door may close too far and hit the ground, or it may not close far enough and leave a gap at the bottom. To check the limit settings, consult the owner's manual for your garage door opener.

7. Power Outages

If there is a power outage, your garage door opener will not be able to function properly. This can cause the door to close and reopen when the power comes back on. To prevent this, you can install a battery backup system for your garage door opener.

Conclusion

If your garage door keeps closing and reopening, there are several possible causes. The best way to determine the cause is to inspect the door and its components carefully. Once you have found the cause, you can take the necessary steps to fix the problem.
