What can cause random openings with garage doors?

Answer 1

If the door is completely closed, but suddenly opens for an unknown reason, it is most likely due to an outside frequency interference. This means that your opener's receiver detects an outside signal and mistakenly recognizes it as its own. This is rather rare but it happens. You can reprogram the opener and the remote pretty easily using the user manual, good luck!
