Examine the garage door opener button.
Garage door keeps opening and closing randomly.
There may also be loose wire connections inside the button housing itself.
It all depends on the configuration but you likely have a button that activates the door operator.
If that doesn t fix the problem check the wiring between the motor unit and the wall control.
The symptom of this is a garage door that is in constant motion opening fully then immediately descending only to start the same cycle again.
To troubleshoot the garage door opener button make sure it s clean and free of debris.
The button can easily get dirty and stuck in the pushed position.
The door operator button is similar to a door bell.
Erase all codes in your remote and then reprogram it.
Whether you re using the passcode entry the buttons inside the garage or your remote opener the openers and the garage door itself must be on the same frequency.
When your garage door opens or closes when you haven t triggered the remote one possible cause is that a neighbor s remote was programmed at the same time as yours.
