5 Reasons Why Garage Doors Open or Close Automatically

Garage doors are essential to our homes, providing security and protection to our vehicles and other valuable belongings. Though they are designed to operate manually or with the help of a remote, sometimes they may open or close automatically without any human intervention. It can be a frustrating and concerning issue for homeowners. But what are the reasons why garage doors open and close on their own?

1. Broken Transmitter or Remote

A broken transmitter or remote is one of the most common reasons garage doors open or close automatically. The transmitter or remote sends signals to the garage door opener to operate the door. If the transmitter or remote is damaged, it can send alerts randomly, causing the door to open or close automatically. Homeowners can replace the transmitter or remote or reprogram the opener to recognize a new signal.

2. Unadjusted Opener Limit 

The opener limit is an essential component of the garage door system that controls the opening and closing of the door. If the opener limit is not adjusted correctly, it can cause the door to open or close automatically. The opener limit determines how far the door should move before it stops.

If the limit is set too high, the door may open or close too far, causing it to hit the ground and reverse direction. If the limit is too low, the door may not close all the way, leaving a gap between the door and the ground. Adjust the opener limit or contact a professional technician to do it.

3. Damaged Electrical Circuits 

Garage doors are powered by electrical circuits that connect the opener to the motor and other components of the system. If these circuits are damaged or short-circuited, they can cause the door to open or close automatically. The issue can be dangerous as it can cause the door to close unexpectedly, posing a safety hazard to anyone in its path. Inspect the electrical circuits for any damage or contact a professional technician to do it for you.

4. Obstructed Sensors 

Garage doors are equipped with safety sensors that detect obstacles in the door’s path. If the sensors are obstructed or dirty, they can cause the door to open or close automatically. The sensors send signals to the opener to stop the door from moving if they detect an obstacle.

If the sensors are dirty or obstructed, they may not detect the obstacle, causing the door to open or close automatically. As a result, even if there is nothing in the driveway, the doors will open and close. Clean the sensors or remove any obstructions from their path to fix this issue.

5. Unsuspecting Neighbor 

One of the least common reasons why garage doors open or close automatically is due to an unsuspecting neighbour. If your neighbour has a remote that operates on the same frequency as yours, it can cause your door to open or close automatically when they use their remote. This issue can be resolved by changing the frequency of your remote or contacting a professional technician to do it for you.

When Do Garage Doors Need Maintenance and Repair Jobs?

Garage doors are mechanical systems requiring regular maintenance and repair jobs to ensure proper functioning. Ideally, a professional technician should inspect and maintain garage doors annually. However, if you notice any irregularities in the operation of your garage door, it is essential to address them immediately to prevent any further damage or safety hazards.


Garage doors are an important part of our homes, and it is essential to address any issues with their operation immediately. Automatic garage door opening or closing can be caused by various factors, including a broken transmitter or remote, unadjusted opener limit, damaged electrical circuits, obstructed sensors, and even the unsuspecting neighbour. Regular maintenance and repair jobs can prevent such issues and ensure the proper functioning of your garage door system. If you are experiencing any problems with your garage door, contact a professional technician for an inspection and repair.
