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.
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.
Erase all codes in your remote and then reprogram it.
There may also be loose wire connections inside the button housing itself.
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.

Clean the button as well as the connections in the housing if this is the case.
As these wires short against the housing the electrical impulse causes the door opener to activate.
When the garage door reaches the open or closed limit it stops.
Garage doors can open and close on their own.
Garage doors use radio frequencies to open and close.
To troubleshoot the garage door opener button make sure it s clean and free of debris.
