My garage door keeps opening on its own. What could be the reason? It wasn't close to a time that I've closed it.
Some one has a CB radio that is set to the frequency of your garage door opener.
Make sure there is nothing close to it the sencer on it mite sence something
something is probably wrong with the sensor I know my cousins garage use to be the same way. but you might want to have it looked at maybe
if you have any cats or pets, they run in front of the sensor causing that or, your sensor could just be messed up, that happened to me, if you get it looked at it might help
