If you’ve ever come home to find your garage door wide open despite having it closed earlier, you know the frustration of a garage door that won’t stay closed. Not only is it an inconvenience, but it can also be a security risk if your garage contains valuable items or if it connects to the interior of your home.

In this article, we will explore the potential causes of a garage door that won’t stay closed and offer some solutions on how to rectify the issue.

Why Won’t The Garage Door Stay Closed?

If your garage door won’t stay closed, it’s likely due to an issue with the spring tension or misaligned. However, there are other reasons why your garage door won’t stay closed such as a broken sensor or a blocked photo-eye. 

Here are possible ways why your garage door won’t stay closed;

1. Sensors Misaligned

Misaligned sensors could be the reason why your garage door won’t stay closed. Sensors are usually located near the bottom of the door on both sides. When working properly, the sensors should be aligned with each other and pointing directly at each other. 

If the sensors are not properly aligned, the door may not be able to detect if there is something in the way, which could cause the door to not stay closed. 

To check if the sensors are properly aligned, simply check to make sure that they are pointing directly at each other. If they are not, realign them and see if that fixes the issue. If the problem persists, you may need to contact a professional garage door technician to inspect.

2. Faulty Garage Door Opener 

A faulty garage door is a common cause of why your garage door won’t stay closed. The problem could be the opener or its remote control, the chain or belt drive, or the limit switch settings.

In order to diagnose the issue, it’s important to check all of the parts and components. If any of them are damaged or worn, it could be preventing the door from closing properly.

3. Damaged Garage Door Spring

A damaged garage door spring can make it difficult to properly close or open a garage door. It is important to check the tension on the springs as they are typically the cause of a garage door not staying closed.

The springs are responsible for controlling the weight of the door, and if they are not tensioned, the door will not close properly. Additionally, a broken spring can cause the door to completely close, but then suddenly open again.

4. Damaged Garage Door Rollers

Damaged garage door rollers can also be the cause of a garage door not staying closed. Garage door rollers can be worn out from long-term use or become damaged from unexpected events, such as an object running into the door.

Signs of damaged rollers include difficulty closing or opening the door, a door that struggles to stay closed, or a door that is noisy when opening or closing. 

When you notice any of these symptoms, then it’s time to replace the garage door rollers.

5. Damaged Garage Door Sensors 

Damaged garage door sensors can also cause a garage door not to stay closed. The sensors are designed to detect an obstruction in the path of the garage door and stop to prevent damage or injury to whatever’s on the garage door’s path.

The sensors may be damaged in a variety of ways such as being bumped, blocked by debris, or even facing direct sunlight for extended periods of time. Additionally, the area surrounding the sensors should be regularly inspected to ensure that there is nothing blocking the sensors.

What Can I Do To Fix A Garage Door That Won’t Close?

There are a few things you can do to fix your garage door that won’t close. First, inspect the door and its tracks to ensure that nothing is blocking it or preventing its normal operation. If an obstruction is present, clear it away and then try to close the door again. If the door still won’t close, check to ensure that the opener is working properly. 

Also, make sure that the power source is active and that the remote is working correctly. If necessary, test the opener’s safety sensors and make sure that the door is properly balanced. 

Here are other methods you can use to fix your garage door that won’t close

  • Check the batteries in the garage door opener. If the batteries are dead, the opener may not be able to send the correct signals to the garage door to make it stay closed.
  • Check the garage door tracks for any obstructions or debris. If there is anything blocking the tracks, remove it and see if this fixes the problem.
  • Check the garage door springs for any signs of damage or wear. If the springs are damaged, they may need to be replaced.
  • Check the garage rollers for signs of wear or damage. If the rollers are worn out, they may need to be replaced.
  • Check the garage door sensors to make sure they are aligned correctly and functioning properly. If the sensors are not working correctly, they may need to be adjusted or replaced. 

However, if any of these fixes are unable to rectify the problem, it’s a good idea to have a professional garage door technician diagnose the problem and recommend the appropriate repair or replacement.
