The most common cause of a garage door not staying closed is the boundary setting. As mentioned above, the limit switch dictates the garage door when it is fully open or closed. If you set the drop limit too much, the garage door will think it hasn't closed completely when it hits the floor. You press the button to close the garage door; it goes down partially, reverses direction and goes up again.
This is most often the result of a dirty or clogged safety device. At the bottom of the door there is a small infrared sensor. Pass a beam a few centimeters above the ground from one side to the other. If something breaks the beam for a fraction of a second, the door is reversed.
This is to prevent pets, children, or even adults from being crushed by the door. Remove the blockage or clean the eye to fix this problem. The door operator button is similar to a doorbell. It all depends on the configuration, but you probably have a button that activates the door operator.
To fix problems with the garage door opening button, make sure it is clean and free of debris. The button can easily get dirty and stuck in the “pressed” position. This will cause the door to open and close until the button comes off. Clean the button, as well as the case connections, if this is the case.
And again, make sure that the wiring around the opening button is not compromised. If there are empty spots in the wiring insulation, anywhere along the cable path, it could cause a short circuit and cause the door to operate. Place yourself in a place where the shadow blocks sunlight from the lens, and close the door with the remote control to fix this problem. When a garage door descends in order but is then immediately reversed, the problem is usually in the sensor's eyes along the side tracks or in the door wheels that get stuck in its path.
But when the door starts to descend on its own, the problem may be due to the logic board of the opening device or to the circuits inside the motor unit itself. The garage door may always open on its own after closing it if there is a short circuit or a bare area in any of these cables. The slightest detection, such as the accumulation of leaves, snow, or ice around the garage door, can cause the door not to close completely. In garage door operators manufactured after 1993, safety devices are required to open the door during the closing cycle when they detect something blocking it.
In addition to the safety sensor being triggered by dirt, a misaligned sensor is another factor that alters the reverse mechanism of the garage door. If all of the problems listed above are not the reason your garage door opens on its own, you may consider checking your control board and transformer. All that is needed for this to happen is for a bare spot on the cable to rub against the metal guide of the door, or another part where the electrical impulse causes the motor unit to activate.

Not only can it expose you and your property to hazards, but pests and intruders can also freely enter your garage without your knowledge. Once the garage door contacts and wires merge, loosen, or wear out, this can send an incorrect signal to the garage door. The garage door works properly thanks to the small-caliber cables that connect the security sensor to the motor unit and to the door. Its reverse mechanism will start immediately and the door will not close until you clean the dirt.
Once the radio frequency interferes with the frequency of the garage opener, there is likely a problem with the garage door. .
