It depends on what kind of unit you have. Some openers have sensors that have one green and one red all the time. Others will have one turn red when they are out of alignment. Aligning them can be a PITA. They are very finicky and sensitive. Most don't have a reset button, but you can do a hard reset by unplugging it for a few minutes. Hope that helps.
