How many times have you returned home to find your garage door opened, although you’re definite to shut it before you have left?
Or, maybe while sitting in your living room, you’ve just noticed that it randomly opens.
If you have experienced this multiple times, perhaps issues are lingering in its system.
This issue can be an alarming security risk to get everything in your garage open for everyone to see, capable of causing you some anxious feelings.
It’s most likely the problem causing is your garage door opener’s remote, frequency processing, electrical systems, limitation settings, or detectors.
Although some of these issues are more serious than others, a garage door mechanic can assist you in resolving these all.
Limitation Settings Issues
The majority of garage doors use what is known as the open and closed limitation setting.
Such configurations inform your garage door how much further up the track it should travel when wide open and just how far down it will travel when fully closed.
Whenever your garage door continues to unlock after shutting it, you will need to change your closed limitation settings.
When these limitations are set so high, the door will touch the ground before the limit of closing.
When this happens, even if the door reaches the ground, it doesn’t indicate that it’s sealed because it hasn’t crossed the restriction mark, making the door unsteady and moving.
Thus, your garage door would appear to shut but will reverse course, keeping you with a propped open garage door.
A similar issue will happen with the opening limit.
When the limit is set so high, the door may not notice and appears to be moving until it opens slightly.
You can configure the settings using the instructional manual, call professional help, or watch the video on how to adjust garage door limit settings.
Safety Sensors Synchronization Issues
After you clean all dirt and accumulation from the sensors near the ground of the garage door track, however, the action of your garage door is partly shutting, flipping, and rising again.
You might have a mismatched sensor.
The activation of the garage door’s reversal function is through these two sensors.
Such two sensors, sometimes known as safety eyes, are positioned on either side of a garage door opening and, in some situations, emit a beam through the door.
For a garage door to operate normally, such sensors must be installed and coordinated.
If the emitted light is blocked, the reverse function prompts, which indicates that something is on track.
It is likely, though, that these two sensors will be misaligned.
If they’re not pointed straight at each other, there seems to be no single steady point of light.
Despite synchronization or obstruction, the LED on the sending sensor would light up.
Unless the led indicator on the receiving sensor is off or blinking, and the light beam direction is clear, your sensors need realignment.
Problems with the safety sensor circuitry are typically caused by a poor connection, improperly installed wires, or a short in the wire caused by a staple.
If this happens, you can configure this yourself, ask for a technician, or watch the video of how to align garage door safety eyes.
Garage Spring Issues
A tension spring is an essential component of garage door service, and once when it fails, everything comes to a halt.
Springs come in sizes, and they’re the solid performer of your garage door’s operation.
Faulty issues with this part could be the answer to, “why would my garage door randomly open?”
It is usual to see the springs snapped, but do not attempt to check by touching it.
If you suspect this is the cause of your garage door not working, contact a garage door specialist to inspect it.
Garage doors are high, and replacing a faulty spring through your own can be risky.
Electrical Circuits and Wiring Issues
Weather conditions may also harm your garage door in some other way.
Power cuts and electrical surges are sometimes happening due to severe storms, lightning storms, and other weather factors.
Once you’ve recently had a power outage or surge, it could have harmed the electrical circuits that control the opening and closure of your garage door.
This form of disruption can cause the garage door to open all by itself.
Also, some wires could be affected, one that connects between the pulse generator and one of the sensors on either side of the garage door tracks, low to the ground.
If either of these small-gauge wires has a weak spot or fault conditions, it may be the one causing the garage door to move on its own.
There are still a lot of issues that raise the question, “why would my garage door randomly open?”
However, the mentioned problems above can be the most prevalent ones and may be the answer to your question.
If you encounter these problems, you can always seek out professional expertise to aid your garage upkeep.
But if you want to do this on your own, remember to be safe.
