To close my garage door you have to hold down the button in the garage? You know how to fix it?

Answer 1

Most likely the safety sensors for the opener have gotten knocked out of alignment.  When this happens you can hold down the wall button as a sort of manual override.  If you cannot get the sensors to work after aligning them, one could have a short in it or could have gone bad.  Hope this helps!
