Garage Door Opening by Itself? Here is Why and What You Can Do About It.
Unlikely circumstances are often inevitable.
Any unusual remarks visible in the garage door might need assistance from skilled garage door specialists.
So, if the garage door opener is opening by itself, there is something wrong with it.
Some parts might be damaged or triggered by a specific factor.
An electric garage door is a complex device.
Its parts are intertwined with each other.
Whenever a part malfunctions, others will be affected, obstructing the operation of the entire door.
Here are the reasons why and what homeowners can do to solve this dilemma.
Contact for immediate assistance if the causes cannot be identified.
Check the safety sensors.
Electric garage doors have sensors that can detect anything struck underneath the door.
Homeowners will be notified if there are any obstructions because there is a blinking light on the opener or at the operator button.
There are sensors in the motor and on each side of the opening, located near the floor and mounted on the tracks.
It can detect even the tiniest obstruction such as snow, leaves, ice, and dirt.
Whenever the door goes up immediately on its own upon closing, there might be something that hinders it.
It will not function if something is blocking the path.
Clear out debris or any fragments that affect its operation.
After clearing out, scan the safety sensors once more.
Another reason might be the misalignment of these sensors.
When it is not functioning correctly, it affects the door as well.
Check these wires’ condition and the connections.
Moreover, if the light is not blinking, the sensors are probably damaged and might need fixing.
Check the garage door opener button.
The garage door has an operator button like a front door has a doorbell.
This button activates the door’s operation.
To check it, ensure it is clean without any debris because dirt gets stuck in it easily upon pushing it.
There is a tendency that it will get stuck which would lead to the door opening and closing simultaneously until it gets unstuck.
So, make sure to clean the button as well as the wires and the connection in the housing.
The cables are also sensitive components that could short circuit the door.
Verify the garage door opener remote.
Aside from the garage door opener, another way to open the garage door is through its remote.
If it malfunctions, the operation of the door will be affected apparently.
Check the remote’s functionality.
Make sure it is clean.
Also, verify the batteries.
The reason might be the loose insertion of batteries, or it is not inserted correctly according to the right position.
Change the batteries if it is concluded to be the reason.
Radio interference is observed.
Garage door depends on radio frequency to operate.
It can be done whether through the passcode entry, the buttons, or the remote opener.
All these openers and the garage door should be on a similar frequency.
Lots of devices use the same frequencies.
If two garage doors are programmed to the same channel, it might confuse the garage door.
The connectivity is interrupted due to similar frequencies that are also used by neighbors or other users.
Worry not, this problem is not difficult to solve.
Issues regarding frequency just need reprogramming the garage door’s openers.
Consider the control board and transformer.
Lastly, if there are no issues seen in the reasons mentioned above, it might concern the control board in the garage door opener.
The board might be damaged due to a power surge caused by electrical problems or a lightning strike.
The transformer will also be affected if these problems arise.
To solve this issue, homeowners can check the voltage of the circuit board and the transformer.
This solution is recommended to those who are knowledgeable and handy with a multimeter.
Furthermore, it is suggested to consider installing a surge protector.
It puts the operator plugs into the receptacle, providing safety for the long run.
They also provide components if there are any necessary replacements.
