You have probably started to notice your garage door opening on its own, and you are worried that this might be a bigger problem. Not only is the opening of your garage door on its own an annoyance and can make you frustrated with the door, but it is also a security threat that leaves your property vulnerable to intruders and unwanted pets. It can also expose you to fines if you live in a community with homeowner associations that call for garage doors to always remain closed.
Why is the garage door opening on its own? Your garage door is opening on its own because of the beam being cut off due to a misaligned photoelectric reversal system. The broken beam makes the garage door control system believe that there is an obstruction in path of the door, and it opens the door as a precaution.
Garaga, a leading manufacturer of garage doors, explains the misaligned beam as a fault that occurs when the photoelectric reversal system is not aligned properly. The company adds that when this happens, the beam is cut off, causing the door to open itself.
What Are the Main Reasons Why Your Garage Door Is Opening on Its Own?
If your garage door opens on its own, then it is important to address the problem as soon as possible. This is because the opening of your garage door on its own is a security threat and can attract unwanted intruders into your property. It also puts your property at risk of getting robbed, or worse. To address the problem, we first need to know the root cause of the opening of the garage. Below are some of the reasons why your garage is opening on its own.
- Beam Misalignment: One of the main functionalities that allows the opening and closing of the garage is the sensors. There are two types of sensors: the emitters that are responsible for sending signals and the receivers, which are responsible for receiving signals from the emitters and then opening or closing the doors. The two sensors also act as a photoelectric safety system for your garage doors. However, if the two sensors become misaligned, it means the sensor beams are cutoff and there is no way of sending and receiving signals as intended. This can cause your garage doors to open on their own after they are closed. Fortunately, the solution to this problem only requires realignment of the beams and ensures that they are working correctly by confirming that the wall panel has stopped blinking.
- Radio Interference: Garage doors can easily be opened by remote controls that contain radio transmitters. In most cases, these transmitters operate on frequencies between 300 MHz and 390 MHz Unfortunately, there are cases where some of the devices in your house or within the surrounding area of your garage operate at the same frequency as your door opener. The result is that when these devices are turned on, they interfere with your garage door and cause it to open on its own. To solve this problem, you should consider reconfiguring your garage door to open at a different frequency. If the first solution does not work, you should also consider changing the code of your garage door opener.
- Problems with your circuit board: There is also a possibility that the garage circuit board has short circuited. This can be because of getting damaged overtime, causing the garage doors to not function properly. To address this, you need to repair your circuit boards by either calling an electrician or replacing them yourself.
- Bad Weather: One of the most overlooked causes of your garage door opening on its own is severe weather. For instance, heavy rain and thunder can wreak havoc on your garage doors and damage them. This can result in your garage door starting to open on its own.
- Problems with your garage door buttons: Sometimes the problem that is causing your garage door to open on its own is not complex and may be a result of a stuck button. If the button is stacked in the open position, then your garage door will open on its own regardless of how many times you try to close it. Fortunately, this problem is easy to fix and only requires one to.
I scoured the online garage owner forums to find out what others are saying about why their garage doors were opening on their own. This table will help you to check even more reasons for your garage door opening on its own.

How Do You Fix a Garage Door That Is Opening on Its Own
Noticing your garage door opening on its own can be a frustrating experience. Fortunately, there are many solutions available to address the causes of your garage door opening on its own. Some of these solutions are:
- Radio frequencies: One of the major reasons why your garage door is opening on its own is due to radio interference. This can be caused by your garage operating on the same frequency as a local radio station, police radios or your neighbor’s garage is configured as yours, and each time they open their garage, the radio frequency also affects your garage door. Fortunately, this is quite a simple problem to solve. You only need to reconfigure your garage and change the frequency it is operating on.
- Clean out debris from your garage door sensors: Garage doors have sensors that help them detect whether the door is fully closed. However, these sensors can sometimes collect dirt and debris and start to malfunction. When that happens, there is no way of telling whether the door is closing or opening, and in most cases, your garage door will open on its own. The solution to this problem is to ensure that the sensors are clean and that the area around the door is also clean. This is to ensure the sensors are working.
- Problems with your remote opener: Sometimes the problem may be due to your garage door remote opener. Ensure that the opener is operating optimally with good batteries and configured to the right frequency, which matches your garage door. You should also consider cleaning the remote and ensuring that there are no stuck buttons that can send signals to your garage doors to open.
- The open and close limit settings are the ones that tell the door how far to open and close. When configured incorrectly, it can result in your door not shutting properly or failing to reach the floor. This can result in your garage door opening. Therefore, always ensure the settings are correct.
- Repair faulty circuits: Faulty circuits can cause your garage door to remain open or closed.
Why Does My Garage Door Open Itself Only at Night?
Your garage door opens itself only at night because your neighbors’ garage doors may be configured like yours, and when they come at night, their remote opener also opens your garage doors. Radiofrequency interference during the night may also be a problem.
If you start noticing that your garage door is opening itself during the night but not during the night, there is a possibility that the events that trigger the opening are only met during the night. One such possibility is that your neighbor has the same garage door as yours and only comes home at night. Each time the neighbor presses their garage door remote opener, it also opens your garage.
Another reason is that during the night is when people are relaxing and listening to their favorite radio stations. These radio stations may be running on the same frequencies as your garage doors. The result is radio interference that results in your garage door opening by itself at night.
There is also a possibility that your doors will open at night due to increased police activity in your area. Some police scanners and radios may be operating in the same frequency as your garage door, and each time police are over the radio, there is radio frequency interference that is causing your garage door to open by itself at night.
Why Does My Liftmaster Garage Door Opening by Itself
Your LiftMaster garage door is opening by itself because of a short circuit in the system. There is also a high likelihood that the opening is a result of radio interference or a malfunctioning remote opener.
The LiftMaster brand is immensely popular with garage owners. Unfortunately, your LiftMaster garage door can start opening itself. When that starts to happen, you must consider multiple reasons as to why that might be the case. One of these reasons is that there is radio frequency interference that is causing your doors to open. This is caused by your garage opener, garage door, and devices such as police radios and scanners operating at the same frequencies. These frequencies are interpreted by your LiftMaster door as signals to open the doors, causing the door to open.
There is also a possibility that there is a short on your circuit board. This can result in the garage door malfunctioning, and in most cases, the default malfunction is your LiftMaster garage door opening itself. Your garage door remote opener buttons may also be stuck on the open signal. This may cause your door to remain open or to remain open regardless of how many times you try to close it. Bad weather has also been shown to be a major cause of your LiftMaster garage doors opening by themselves. This mostly happens during heavy rains with thunderstorms that affect the electrical circuit and can cause a short circuit causing the door to open by itself. You should also consider whether your LiftMaster garage door signals at the bottom are getting blocked by dirt. This can cause the signals to be misinterpreted, resulting in garage doors opening.
