Garage Door Almost Closes Then Goes Back Up

If your garage door almost closes then goes back up, there are a few potential causes. One possibility is that the safety sensors are misaligned. These sensors are located on either side of the door and they emit a beam of light. If the beam is broken, the door will automatically reverse to prevent it from closing on someone or something. To fix this, simply realign the sensors so that the beam of light is not broken.

Another possibility is that the door is unbalanced. This can happen if the springs that help to lift the door are not properly adjusted. When the door is unbalanced, it can put extra strain on the motor, causing it to overheat and shut off. To fix this, you will need to adjust the springs so that the door is balanced. You can do this by following the instructions in your garage door owner's manual.

If you have checked the safety sensors and the door is still not closing properly, the problem may be with the motor. The motor is responsible for lifting and lowering the door, and if it is not working properly, the door will not be able to close all the way. To fix this, you will need to replace the motor. You can do this yourself if you are handy, or you can hire a professional to do it for you.

Finally, if you have checked all of the above and the door is still not closing properly, the problem may be with the door itself. The door may be warped or damaged, and this can prevent it from closing properly. To fix this, you will need to replace the door. You can do this yourself if you are handy, or you can hire a professional to do it for you.

Here are some additional tips that may help you troubleshoot your garage door problem:

Check the power to the garage door opener. Make sure that the power is turned on and that the outlet is working properly.

Lubricate the moving parts of the garage door. This will help to reduce friction and make the door easier to open and close.

Inspect the weatherstripping around the garage door. Make sure that the weatherstripping is in good condition and that it is not preventing the door from closing properly.

If you have tried all of the above and the door is still not closing properly, you may need to call a professional for help.
