Technician (Austin) lowered the sensors to fix the problem of the door not stopping when you try to stop it at about a foot from the ground. We asked previous technician (Cody) to lower the sensors but he said he could not do it because he could not attach the bracket to the concrete. However, Austin was able to attach it to the guide rail itself at a lower elevation. We could have avoided another service fee charge of $129.00 if Cody knew how to do it, when he replaced the torsion springs the first time we called for service from Aaron Overhead Doors.
