Kung Fu Maintenance and a friend show you the first things to check for when you have a garage door that will not close or stay closed.
Maintaining garages if your garages aren’t working properly a lot of times it’s something across these lasers. It really doesn’t take much. Even spider webs with leaves can block it and interfere with the garage closing so that is one of the first things to check. Clear any webs out.
The other way to tell if the garage door sensors aren’t lined up is these lights will be off. Soon as they are lined up the lights will turn back on. See off, than on, off, on.
