Why Does Your Garage Door Close and Open Again?

A garage door is a convenient way to enter and exit your home, but it can be frustrating when it doesn’t work properly. One common problem is that the door will close and then reopen immediately. This can be caused by a number of factors, including:

Garage Door Close And Open Again
  • Safety sensors: Garage doors have safety sensors that are designed to prevent the door from closing on something or someone. If the sensors are misaligned, dirty, or damaged, the door may reopen to avoid a collision.
  • Limit switches: Limit switches tell the garage door opener how far to open and close the door. If the limit switches are not set properly, the door may not close all the way or it may reopen after it closes.
  • Springs: The springs help to open and close the garage door. If the springs are broken or weak, the door may not have enough power to close all the way.
  • Opener motor: The opener motor is responsible for lifting and lowering the garage door. If the motor is damaged or not working properly, the door may not close all the way.

How to Fix a Garage Door That Closes and Then Reopens

If your garage door is closing and then reopening, there are a few things you can do to try to fix the problem:

  1. Check the safety sensors. Make sure that the sensors are aligned properly and that they are not blocked by anything. If the sensors are dirty, you can clean them with a soft cloth.
  2. Check the limit switches. Make sure that the limit switches are set properly. You can usually find instructions on how to adjust the limit switches in the garage door opener’s manual.
  3. Check the springs. If the springs are broken or weak, you will need to replace them. This is a job that is best left to a professional.
  4. Check the opener motor. If the opener motor is damaged or not working properly, you will need to replace it. This is a job that is best left to a professional.

Garage Door Close And Open Again

If your garage door is closing and then reopening, it can be a frustrating inconvenience. There are a number of reasons why this might happen, but the good news is that it’s usually a relatively easy fix.

In this article, we’ll take a look at some of the most common causes of a garage door that closes and then reopens, and we’ll show you how to fix the problem.

Safety Sensors

One of the most common reasons for a garage door to close and then reopen is a problem with the safety sensors. These sensors are located near the bottom of the door, and they’re designed to prevent the door from closing on something or someone.

If the safety sensors are misaligned, dirty, or damaged, the door may reopen to avoid a collision. To check the safety sensors, first make sure that they’re aligned properly. You can usually do this by looking at the sensors and making sure that the beams of light are aligned.

If the sensors are aligned properly, but the door is still reopening, try cleaning the sensors. You can do this with a soft cloth and some mild soap. If the sensors are still dirty, you may need to replace them.

Limit Switches

Another common cause of a garage door that closes and then reopens is a problem with the limit switches. These switches tell the garage door opener how far to open and close the door.

If the limit switches are not set properly, the door may not close all the way or it may reopen after it closes. To check the limit switches, first consult your garage door opener’s manual. The manual will usually have instructions on how to adjust the limit switches.

Once you’ve found the instructions, follow them to adjust the limit switches. Be careful not to over-adjust the limit switches, as this can damage the garage door opener.

Springs

The springs help to open and close the garage door. If the springs are broken or weak, the door may not have enough power to close all the way.

To check the springs, first look at them to see if they are broken. You can also try lifting the door manually. If the door is difficult to lift, the springs are likely weak and need to be replaced. Replacing garage door springs is a dangerous job and should only be done by a professional.

Opener Motor

The opener motor is responsible for lifting and lowering the garage door. If the motor is damaged or not working properly, the door may not close all the way.

To check the opener motor, first listen to it when you try to close the door. If the motor sounds like it’s struggling, it may be damaged. You can also try disconnecting the power to the opener and then manually opening and closing the door. If the door is easy to open and close manually, but difficult to open and close with the opener, the motor is likely the problem. Replacing the garage door opener motor is also a job that should only be done by a professional.

Additional Tips:

  • Consult your garage door opener’s manual: Your manual will have troubleshooting tips specific to your model of opener.
  • Be careful when troubleshooting: Don’t attempt to fix any electrical components of the garage door opener yourself. If you’re not comfortable troubleshooting the problem, call a professional.
  • Preventative maintenance: Regularly lubricating the garage door opener and tracks can help to prevent problems from occurring in the first place.

Conclusion

A garage door that closes and then reopens can be a nuisance, but it’s usually a relatively easy fix. By following the troubleshooting tips in this article, you should be able to identify the cause of the problem and get your garage door working properly again. If you’re not comfortable troubleshooting the problem yourself, or if the problem is beyond your expertise, always call a professional garage door repair technician.
